Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	BASIS OF PRESENTATION The Condensed Consolidated Financial Statements include the accounts of LCI Industries and its wholly-owned subsidiaries ("LCII" and collectively with its subsidiaries, the "Company," "we," "us," or "our"). LCII has no unconsolidated subsidiaries. LCII, through its wholly-owned subsidiary, Lippert Components, Inc. and its subsidiaries (collectively, "Lippert Components," "LCI," or "Lippert"), supplies, domestically and internationally, a broad array of engineered components for the leading original equipment manufacturers ("OEMs") in the recreation and transportation product markets, consisting primarily of recreational vehicles ("RVs") and adjacent industries including buses; trailers used to haul boats, livestock, equipment, and other cargo; trucks; boats; trains; manufactured homes; and modular housing. The Company also supplies engineered components to the related aftermarkets of these industries, primarily by selling to retail dealers, wholesale distributors, and service centers. At September 30, 2021, the Company operated over 100 manufacturing and distribution facilities located throughout North America, Europe, and Asia. Most industries where the Company sells products or where its products are used historically have been seasonal and are generally at the highest levels when the weather is moderate. Accordingly, the Company’s sales and profits have generally been the highest in the second quarter and lowest in the fourth quarter. However, because of fluctuations in dealer inventories, the impact of international, national, and regional economic conditions, consumer confidence on retail sales of RVs, and other products for which the Company sells its components, the timing of dealer orders, and the impact of severe weather conditions on the timing of industry-wide shipments from time to time, current and future seasonal industry trends may be different than in prior years, particularly as a result of the coronavirus ("COVID-19") pandemic and related impacts. Additionally, sales of certain engineered components to the aftermarket channels of these industries tend to be counter-seasonal, but may be different in the remainder of 2021 and future years as a result of the COVID-19 pandemic and related impacts. The Company is not aware of any significant events, except as disclosed in the Notes to Condensed Consolidated Financial Statements, which occurred subsequent to the balance sheet date but prior to the filing of this report that would have a material impact on the Condensed Consolidated Financial Statements. In the opinion of management, the information furnished in this Form 10-Q reflects all adjustments necessary for a fair statement of the financial position and results of operations for the interim periods presented. The Condensed Consolidated Financial Statements have been prepared in accordance with the instructions to Form 10-Q, and therefore do not include some information necessary to conform to annual reporting requirements. Results for interim periods should not be considered indicative of results for the full year. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, net sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to product returns, sales and purchase rebates, accounts receivable, inventories, goodwill and other intangible assets, net assets of acquired businesses, income taxes, warranty and product recall obligations, self-insurance obligations, operating lease right-of-use assets and obligations, asset retirement obligations, long-lived assets, pension and post-retirement benefits, stock-based compensation, segment allocations, contingent consideration, environmental liabilities, contingencies, and litigation. The Company bases its estimates on historical experience, other available information, and various other assumptions believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other resources. Actual results and events could differ significantly from management estimates. COVID-19 Update The COVID-19 pandemic has caused significant uncertainty and disruption in the global economy and financial markets. The COVID-19 pandemic had an adverse effect on the Company's financial results during the first half of 2020 due to

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Condensed Consolidated Financial Statements presented herein have been prepared by the Company in accordance with the accounting policies described in its December 31, 2020 Annual Report on Form 10-K and should be read in conjunction with the Notes to Consolidated Financial Statements which appear in that report. All significant intercompany balances and transactions have been eliminated. The Company's accounting policies related to the convertible note hedge and warrant transactions, including the related earnings per share considerations, are disclosed in Note 3 and Note 12 of the Notes to Condensed Consolidated Financial Statements. Recently adopted accounting pronouncement In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity ("ASU 2020-06"). This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. ASU 2020-06 also amends the diluted earnings per share calculation for convertible instruments by requiring the use of the if-converted method. The Company has chosen to early adopt ASU 2020-06 in 2021. This ASU had no retrospective changes but impacted how the convertible debt the Company issued in May 2021 was both recognized and disclosed.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE The following reconciliation details the denominator used in the computation of basic and diluted earnings per share for the periods indicated: Three Months Ended Nine Months Ended (In thousands) 2021 2020 2021 2020 Weighted average shares outstanding for basic earnings per share 25,286 25,162 25,247 25,125 Common stock equivalents pertaining to stock-based awards 131 151 124 95 Weighted average shares outstanding for diluted earnings per share 25,417 25,313 25,371 25,220 Equity instruments excluded from diluted net earnings per share calculation as the effect would have been antidilutive 140 119 142 113 For the Company's 1.125 percent convertible senior notes due 2026 (the "Convertible Notes") issued in May 2021, the dilutive effect is calculated using the if-converted method in accordance with ASU 2020-06. The Company is required, pursuant to the indenture governing the Convertible Notes, dated May 13, 2021, by and between the Company and U.S. Bank National Association, as trustee (the "Indenture"), to settle the principal amount of the Convertible Notes in cash and may elect to settle the remaining conversion obligation (i.e., the stock price in excess of the conversion price) in cash, shares of the Company's common stock, or a combination thereof. Under the if-converted method, we include the number of shares required to satisfy the conversion obligation, assuming all the Convertible Notes are converted. The average closing price of the Company's common stock for the three and nine months ended September 30, 2021 is used as the basis for determining the dilutive effect on earnings per share. The average price of the Company's common stock for each of the three and nine months ended September 30, 2021 was less than the conversion price of $165.65, and, therefore, all associated shares were antidilutive. In conjunction with the issuance of the Convertible Notes, the Company, in privately negotiated transactions with certain commercial banks ("the Counterparties") sold warrants to purchase 2.8 million shares of the Company's common stock (the "Warrants"). The Warrants have a strike price of $259.84 per share, subject to customary anti-dilution adjustments. For calculating the dilutive effect of the Warrants, the Company uses the treasury stock method. With this method, the Company assumes exercise of the Warrants at the beginning of the period, or at time of issuance if later, and issuance of common shares upon exercise. Proceeds from the exercise of the Warrants are assumed to be used to repurchase shares of the Company's common stock at the average market price during the period. The incremental shares, representing the number of shares assumed to be received upon the exercise of the Warrants less the number of shares repurchased, are included in diluted shares. For periods where the Warrants' strike price of $259.84 per share is greater than the average share price of the Company's common stock for the period, the Warrants would be antidilutive. For each of the three and nine months ended September 30, 2021, the average share price was below the Warrant strike price, and therefore 2.8 million shares were considered antidilutive. In connection with the issuance of the Convertible Notes, the Company entered into privately negotiated call option contracts on the Company's common stock (the "Convertible Note Hedge Transactions") with the Counterparties. The Company paid an aggregate amount of $100.1 million to the Counterparties pursuant to the Convertible Note Hedge Transactions. The Convertible Note Hedge Transactions cover, subject to anti-dilution adjustments substantially similar to those in the Convertible Notes, approximately 2.8 million shares of the Company's common stock, the same number of shares initially underlying the Convertible Notes, at a strike price of approximately $165.65, subject to customary anti-dilution adjustments. The Convertible Note Hedge Transactions will expire upon the maturity of the Convertible Notes, subject to earlier exercise or termination. Exercise of the Convertible Note Hedge Transactions would reduce the number of shares of the Company's common stock outstanding, and therefore would be antidilutive.

Acquisitions, Goodwill And Other Intangible Assets [Abstract]
Acquisitions, Goodwill And Other Intangible Assets	ACQUISITIONS, GOODWILL AND OTHER INTANGIBLE ASSETS Subsequent Event Exertis In October 2021, the Company acquired certain business assets of Stampede Presentation Products, Inc. d/b/a Exertis (“Exertis”), a global distribution company, in exchange for $39.7 million, subject to customary adjustments related to working capital. The acquisition qualifies as a business combination for accounting purposes and will support the recent acquisition of Furrion Holdings Limited ("Furrion") by allowing the Company to provide logistics and warehousing to serve Furrion's North American customer base. Acquisitions Completed During the Nine Months Ended September 30, 2021 Furrion In September 2021, the Company acquired 100 percent of the share capital of Furrion, a leading distributor of a large range of appliances and other products to OEMs and aftermarket customers in the RV, specialty vehicle, utility trailer, horse trailer, marine, transit bus, and school bus industries. The total fair value of consideration, net of cash acquired, was approximately $146.7 million. The Company paid $50.5 million in cash consideration at closing, net of cash acquired, with $31.3 million due on each of the first and second anniversaries of the acquisition in September 2022 and September 2023. The deferred acquisition fixed payments are recorded at their respective discounted present values in the Condensed Consolidated Balance Sheet in accrued expenses and other current liabilities and other long-term liabilities at September 30, 2021. In 2019, the Company and Furrion agreed to terminate an exclusive distribution and supply agreement, and transition all sale and distribution of Furrion products then handled by the Company to Furrion. Effective January 1, 2020, Furrion took responsibility for distributing its products directly to the customer and assumed all responsibilities previously carried out by the Company relating to Furrion products. Upon termination of the agreement, Furrion purchased from the Company all non-obsolete stock and certain obsolete and slow-moving stock of Furrion products at the cost paid by the Company. At the date of the Furrion acquisition in September 2021, the Company had a receivable balance of $35.0 million and Furrion had a corresponding payable balance. In direct connection with the acquisition negotiations, the receivable and payable were effectively settled in the acquisition and the receivable balance is included within the approximate $146.7 million of consideration transferred. No gain or loss was recognized in the effective settlement of the receivable. The purchase price is subject to customary adjustments for cash, working capital, and indebtedness. The results of the acquired business have been included in the Condensed Consolidated Statements of Income since the acquisition date, in both the Company's OEM and Aftermarket Segments.

The current estimates for intangible assets are based on the Company's historical acquisitions and estimated projections for the acquired company. These estimates will be updated to the valuation when it is finalized within the measurement period (not to exceed 12 months from the acquisition date).

The accounting for these acquisitions is incomplete at September 30, 2021. The estimated fair values of assets acquired and liabilities assumed are based on preliminary allocations and will be finalized during the respective measurement periods, which will not exceed 12 months from the respective acquisition dates.

Retirement Benefits [Abstract]
Pension Plans	PENSION PLANS The acquisition of Polyplastic Group B.V. in January 2020 included the assumption of two partially-funded defined benefit pension plans (the "Dutch pension plans") based in the Netherlands. The Dutch pension plans, which are qualified defined benefit pension plans, provide benefits based on years of service and average pay. The benefits earned by the employees are immediately vested. The Company funds the future obligations of the Dutch pension plans by purchasing an insurance contract from a large multi-national insurance company. Each year, the Company makes premium payments to the insurance company (1) to provide for the benefit obligation of the current year of service based on each employee's age, gender, and current salary, and (2) for indexations for both active and post-active participants. The Company determines the fair value of the plan assets with the assistance of an actuary using unobservable inputs (Level 3), which is determined as the present value of the accrued benefits guaranteed by the insurer. The components of net periodic pension cost for the Dutch pension plans were as follows: Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2021 2020 2021 2020 Net service cost $ (1,084) $ (859) $ (3,300) $ (2,484) Interest cost (163) (259) (495) (745) Expected return on plan assets 105 161 322 463 Administrative charges (71) (73) (214) (203) Net periodic pension cost $ (1,213) $ (1,030) $ (3,687) $ (2,969)

Long-Term Indebtedness	LONG-TERM INDEBTEDNESS Long-term indebtedness consisted of the following at: September 30, December 31, (In thousands) 2021 2020 Convertible Notes $ 460,000 $ — Revolving Credit Loan 305,074 394,888 Term Loan 273,750 285,000 Shelf-Loan Facility 50,000 50,000 Other 9,324 9,652 Unamortized deferred financing fees (11,759) (1,291) 1,086,389 738,249 Less current portion (74,311) (17,831) Long-term indebtedness $ 1,012,078 $ 720,418 Amended Credit Agreement On December 14, 2018, the Company and certain of its subsidiaries refinanced its credit agreement with JPMorgan Chase, N.A., Wells Fargo Bank, N.A., Bank of America, N.A., and other bank lenders (as amended, the “Amended Credit Agreement”). The Amended Credit Agreement amended and restated an existing credit agreement dated April 27, 2016 and now expires on December 14, 2023. The Amended Credit Agreement increased the revolving credit facility from $325.0 million to $600.0 million, and permits the Company to borrow up to $250.0 million in approved foreign currencies, including Australian dollars, Canadian dollars, pounds sterling, and euros ($160.1 million, or €138.0 million drawn at September 30, 2021). On December 19, 2019, the Company and certain of its subsidiaries entered into an Incremental Joinder and Amendment No. 1 (“Amendment No. 1”) of the Amended Credit Agreement with several banks, which provided an incremental term loan in the amount of $300.0 million, which the Company borrowed to fund a portion of the purchase price for the acquisition of CURT. The term loan is required to be repaid in an amount equal to 1.25% of original principal amount of the term loan for the first eight quarterly periods commencing March 31, 2020, and then 1.875% of the original principal amount of the term loan for each quarter thereafter, until the maturity date of December 14, 2023. In addition, Amendment No. 1 modified the credit agreement to allow the Company to request an increase to the facility of up to an additional $300.0 million as an increase to the revolving credit facility or one, or more, incremental term loan facilities upon approval of the lenders and the Company receiving certain other consents. As a result of the new incremental term loan, the total borrowing capacity under the Amended Credit Agreement was increased from $600.0 million to $900.0 million. On May 7, 2021, the Company and certain of its subsidiaries entered into an Amendment No. 2 of the Amended Credit Agreement with several banks, which modified provisions to, among other things, permit the issuance of the Convertible Notes and permit the entry into the related Convertible Note Hedge Transactions and Warrant transactions ("Warrant Transactions"). See Note 12 of the Notes to Condensed Consolidated Financial Statements for further details of the Convertible Note Hedge Transactions and Warrant Transactions. On September 7, 2021, the Company and certain of its subsidiaries entered into an Amendment No. 3 of the Amended Credit Agreement with several banks, which modified provisions of the Amended Credit Agreement, to, among other things, permit the Company to acquire Furrion and to revise the benchmark replacement language relating to Eurocurrency borrowings. Interest on borrowings under the revolving credit facility and incremental term loan are designated from time to time by the Company as either (i) the Alternate Base Rate (defined in the Amended Credit Agreement as the greatest of (a) the Prime Rate of JPMorgan Chase Bank, N.A., (b) the federal funds effective rate plus 0.5 percent, and (c) the Adjusted LIBO Rate (as defined in the Amended Credit Agreement) for a one month interest period plus 1.0 percent), plus additional interest ranging from 0.0 percent to 0.625 percent (0.375 percent at September 30, 2021) depending on the Company’s total net leverage ratio, or (ii) the Adjusted LIBO Rate for a period equal to one, two, three, six, or twelve months (with the consent of each lender) as selected by the Company, plus additional interest ranging from 0.875 percent to 1.625 percent (1.375 percent at September 30, 2021) depending on the Company’s total net leverage ratio. At September 30, 2021, the Company had $27.8 million in issued, but undrawn, standby letters of credit under the revolving credit facility. Availability under the Company’s revolving credit facility was $267.2 million at September 30, 2021. Shelf-Loan Facility On February 24, 2014, the Company and certain of its subsidiaries entered into a $150.0 million shelf-loan facility (as amended and restated, the “Shelf-Loan Facility”) with PGIM, Inc. (formerly Prudential Investment Management, Inc.) and its affiliates (“Prudential”). On March 20, 2015, the Company issued $50.0 million of Senior Promissory Notes (“Series A Notes”) to Prudential for a term of five years, at a fixed interest rate of 3.35 percent per annum, payable quarterly in arrears. On March 29, 2019, the Company issued $50.0 million of Series B Senior Notes (the “Series B Notes”) to certain affiliates of Prudential for a term of three years, at a fixed interest rate of 3.80 percent per annum, payable quarterly in arrears, of which the entire amount was outstanding at September 30, 2021. The net proceeds of the Series B Notes were used to repay the Series A Notes. On November 11, 2019, the Company and certain of its subsidiaries amended and restated the Shelf-Loan Facility to provide for a new $200.0 million shelf facility pursuant to which the Series B Notes are currently outstanding and to conform certain covenants to the Amended Credit Agreement. The Shelf-Loan Facility expires on November 11, 2022. On March 31, 2020, the Company and certain of its subsidiaries entered into a Consent and Amendment to the Shelf-Loan Facility to join certain Company subsidiaries that were acquired in the CURT acquisition as guarantors and permit other internal restructuring matters related to certain of the Company's subsidiaries. On September 21, 2020, the Company and certain of its subsidiaries entered into a Second Amendment to the Shelf-Loan Facility to conform additional covenants to the Amended Credit Agreement. On May 7, 2021, the Company and certain of its subsidiaries entered into a Third Amendment to the Shelf-Loan Facility to permit the issuance of the Convertible Notes and permit the entry into the related Convertible Note Hedge Transactions and Warrant Transactions. On September 7, 2021, the Company and certain of its subsidiaries entered into a Fourth Amendment to the Shelf-Loan Facility to permit the Company to, among other things, acquire Furrion. The Shelf-Loan Facility provides for Prudential to consider purchasing, at the Company’s request, in one or a series of transactions, additional Senior Promissory Notes of the Company in the aggregate principal amount of up to $150.0 million (excluding the Company’s Series B Notes already outstanding). Prudential has no obligation to purchase the Senior Promissory Notes. Interest payable on the Senior Promissory Notes will be at rates determined by Prudential within five business days after the Company issues a request to Prudential. Convertible Notes On May 13, 2021, the Company issued $460.0 million in aggregate principal amount of 1.125 percent convertible senior notes due 2026 in a private placement to certain qualified institutional buyers, resulting in net proceeds to the Company of approximately $448.0 million after deducting the initial purchasers' discounts and offering expenses payable by the Company. The Convertible Notes bear interest at a coupon rate of 1.125 percent per annum, payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2021. The Convertible Notes will mature on May 15, 2026, unless earlier converted, redeemed, or repurchased, in accordance with their terms. No sinking fund is provided for the Convertible Notes. There are no registration rights associated with the Convertible Notes or the common stock issuable upon conversion of the Convertible Notes. The initial conversion rate of the Convertible Notes is 6.0369 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes, which is equal to an initial conversion price of approximately $165.65 per share of the Company's common stock. The conversion rate of the Convertible Notes is subject to adjustment upon the occurrence of certain specified events, but will not be adjusted for accrued and unpaid interest on any Convertible Note being converted, except in limited circumstances. In addition, upon the occurrence of a make-whole fundamental change (as defined in the Indenture) or upon a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder that elects to convert its Convertible Notes in connection with such make-whole fundamental change or notice of redemption, as the case may be. Prior to the close of business on the business day immediately preceding January 15, 2026, the Convertible Notes are convertible at the option of the holders only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price (as defined in the Indenture) per share of the Company's common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 percent of the conversion price for the Convertible Notes on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the "measurement period") in which the trading price (as defined in the Indenture) per $1,000 principal amount of the Convertible Notes for each trading day of the measurement period was less than 98 percent of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; (3) if the Company calls such Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Notes called (or deemed called) for redemption; or (4) upon the occurrence of certain specified corporate events described in the Indenture. On or after January 15, 2026, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case may be, cash, shares of the Company's common stock, or a combination of cash and shares of the Company's common stock, at the Company's election, in respect of the remainder, if any, of the Company's conversion obligation in excess of the aggregate principal amount of the notes being converted. The Company may not redeem the Convertible Notes prior to May 20, 2024. On or after May 20, 2024, the Company may redeem for cash all or any portion of the Convertible Notes, at the Company's option, if the last reported sale price of the Company's common stock has been at least 130 percent of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100 percent of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. Upon the occurrence of a fundamental change (as defined in the Indenture), subject to certain conditions, holders of the Convertible Notes may require the Company to repurchase for cash all or any portion of their Convertible Notes in principal amounts of $1,000 or an integral multiple thereof at a repurchase price equal to 100 percent of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest on such notes to, but not including, the fundamental change repurchase date (as defined in the Indenture). The Convertible Notes are senior unsecured obligations and rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Convertible Notes, equal in right of payment with all the Company's liabilities that are not so subordinated, effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the named trustee or the holders of at least 25 percent of the aggregate principal amount of the outstanding Convertible Notes may declare 100 percent of the principal of, and accrued and unpaid interest, if any, on all the outstanding Convertible Notes to be due and payable. The Convertible Notes are not registered securities nor listed on any securities exchange but may be actively traded by qualified institutional buyers. The fair value of the Convertible Notes of $478.4 million at September 30, 2021 was estimated using Level 1 inputs, as it is based on quoted prices for these instruments in active markets. General At September 30, 2021, the fair value of the Company's long-term debt under the Amended Credit Agreement and the Shelf-Loan Facility approximates the carrying value, as estimated using quoted market prices and discounted future cash flows based on similar borrowing arrangements. Borrowings under both the Amended Credit Agreement and the Shelf-Loan Facility are secured on a pari-passu basis by first priority liens on the capital stock or other equity interests of the Company’s direct and indirect subsidiaries (including up to 65 percent of the equity interests of certain "controlled foreign corporations"). Pursuant to the Amended Credit Agreement and Shelf-Loan Facility, the Company shall not permit its net leverage ratio to exceed certain limits, shall maintain a minimum debt service coverage ratio, and must meet certain other financial requirements. At September 30, 2021, the Company was in compliance with all such requirements. The Amended Credit Agreement and the Shelf-Loan Facility include a maximum net leverage ratio covenant which limits the amount of consolidated outstanding indebtedness that the Company may incur on a trailing twelve-month EBITDA, as defined in the Amended Credit Agreement and the Shelf-Loan Facility. This limitation did not impact the Company's ability to incur additional indebtedness under its revolving credit facility at September 30, 2021. The combined remaining availability

Leases [Abstract]
Leases	LEASES The Company leases certain manufacturing and warehouse facilities, administrative office space, semi-tractors, trailers, forklifts, and other equipment through operating leases with unrelated third parties. The increase in lease costs for the three and nine months ended September 30, 2021 compared to the three and nine months ended September 30, 2020 was primarily driven by capacity expansions and leases assumed in recent acquisitions. The components of lease cost were as follows: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Operating lease cost $ 11,280 $ 8,343 $ 31,695 $ 24,319 Short-term lease cost 1,247 475 3,122 1,744 Variable lease cost 923 553 2,354 1,700 Total lease cost $ 13,450 $ 9,371 $ 37,171 $ 27,763

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Contingent Consideration In connection with several business acquisitions, if certain performance targets for the acquired products are achieved, the Company would pay additional cash consideration. The Company has recorded a liability for the fair value of this contingent consideration at September 30, 2021, based on the present value of the expected future cash flows using a market participant’s weighted average cost of capital of 13.3 percent. As required, the liability for this contingent consideration is measured at fair value quarterly, considering actual sales of the acquired products, updated sales projections, and the updated market participant weighted average cost of capital. Depending upon the weighted average costs of capital and future sales of the products which are subject to contingent consideration, the Company could record adjustments in future periods. The following table provides a reconciliation of the Company’s contingent consideration liability for the nine months ended September 30, 2021: (In thousands) Balance at beginning of period $ 4,609 Acquisitions 5,000 Payments (3,183) Accretion (a) 173 Fair value adjustments (a) (b) 394 Net foreign currency translation adjustment (141) Balance at end of the period (b) 6,852 Less current portion in accrued expenses and other current liabilities (5,006) Total long-term portion in other long-term liabilities $ 1,846 (a) Recorded in selling, general and administrative expenses in the Condensed Consolidated Statements of Income. (b) Amount represents the fair value of estimated remaining payments. The total estimated remaining undiscounted payments as of September 30, 2021 were $8.4 million. The liability for contingent consideration expires at various dates through September 2029. Certain of the contingent consideration arrangements are subject to a maximum payment amount, while the remaining arrangements have no maximum contingent consideration. Product Recalls From time to time, the Company cooperates with and assists its customers on their product recalls and inquiries, and occasionally receives inquiries directly from the National Highway Traffic Safety Administration regarding reported incidents involving the Company’s products. As a result, the Company has incurred expenses associated with product recalls from time to time, and may incur expenditures for future investigations or product recalls. Environmental The Company’s operations are subject to certain Federal, state, and local regulatory requirements relating to the use, storage, discharge, and disposal of hazardous materials used during the manufacturing processes. Although the Company believes its operations have been consistent with prevailing industry standards and are in substantial compliance with applicable environmental laws and regulations, one or more of the Company’s current or former operating sites, or adjacent sites owned by third-parties, have been affected, and may in the future be affected, by releases of hazardous materials. As a result, the Company may incur expenditures for future investigation and remediation of these sites, including in conjunction with voluntary remediation programs or third-party claims. Litigation In the normal course of business, the Company is subject to proceedings, lawsuits, regulatory agency inquiries, and other claims. All such matters are subject to uncertainties and outcomes that are not predictable with assurance. While these matters could materially affect operating results when resolved in future periods, management believes that, after final disposition, including anticipated insurance recoveries in certain cases, any monetary liability or financial impact to the Company beyond that provided in the Condensed Consolidated Balance Sheet as of September 30, 2021, would not be material to the Company’s financial position or results of operations.

Recipients of DSUs and RSUs are entitled to receive shares at the end of a specified vesting or deferral period. Holders of DSUs and RSUs receive dividend equivalents based on dividends granted to holders of the common stock, which dividend equivalents are payable in additional DSUs and RSUs, and are subject to the same vesting criteria as the original grant. DSUs vest (i) ratably over the service period, (ii) at a specified future date, or (iii) for certain officers, based on achievement of specified performance conditions. RSUs vest (i) ratably over the service period or (ii) at a specified future date. Transactions in DSUs and RSUs under the LCI Industries Equity Award and Incentive Plan, as Amended and Restated (the "2011 Plan") or the 2018 Plan, as applicable, are summarized as follows: Number of Shares Weighted Average Price Outstanding at December 31, 2020 335,087 $ 90.04 Issued 3,662 132.68 Granted 104,930 142.98 Dividend equivalents 5,547 129.82 Forfeited (4,883) 115.05 Vested (163,179) 87.63 Outstanding at September 30, 2021 281,164 $ 109.85 Performance Stock Units The 2018 Plan provides for performance stock units ("PSUs") that vest at a specific future date based on achievement of specified performance conditions. Transactions in PSUs under the 2018 Plan are summarized as follows: Number of Shares Weighted Average Price Outstanding at December 31, 2020 119,727 $ 89.92 Granted 40,102 143.54 Dividend equivalents 2,891 129.79 Forfeited (1,053) 96.55 Vested (12,593) 95.03 Outstanding at September 30, 2021 149,074 $ 104.01 Convertible Note Hedge Transactions The Company paid an aggregate amount of $100.1 million to the Counterparties pursuant to the Convertible Note Hedge Transactions. The Convertible Note Hedge Transactions cover, subject to anti-dilution adjustments substantially similar to those in the Convertible Notes, approximately 2.8 million shares of the Company's common stock, the same number of shares initially underlying the Convertible Notes, at a strike price of approximately $165.65, subject to customary anti-dilution adjustments. The Convertible Note Hedge Transactions will expire upon the maturity of the Convertible Notes, subject to earlier exercise or termination. The Convertible Note Hedge Transactions are expected generally to reduce the potential dilutive effect to the Company's common stock of the conversion of the Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the Convertible Notes which are converted, as the case may be, in the event the price per share of the Company's common stock, as measured under the terms of the Convertible Note Hedge Transactions, is greater than the strike price of the Convertible Note Hedge Transactions. The Convertible Note Hedge Transactions meet the criteria in Accounting Standards Codification ("ASC") 815-40 to be classified within stockholders' equity, and therefore the Convertible Note Hedge Transactions are not revalued after their issuance. The Convertible Notes and the Convertible Note Hedge Transactions will be integrated for tax purposes. The accounting impact of this tax treatment makes the Convertible Note Hedge Transactions deductible as original issue discount for tax purposes over the term of the Convertible Notes, and results in a $24.4 million deferred tax asset recognized through equity. Warrant Transactions In addition, concurrently with entering into the Convertible Note Hedge Transactions, the Company entered into separate, privately-negotiated Warrant Transactions with the Counterparties, whereby the Company sold Warrants to purchase 2.8 million shares of the Company's common stock at an initial strike price of $259.84 per share, subject to customary anti-dilution adjustments, which is approximately 100 percent above the last reported sale price of the Company's common stock on May 10, 2021. The Company received aggregate proceeds of $48.5 million from the Warrant Transactions with the Counterparties, with such proceeds partially offsetting the costs of entering into the Convertible Note Hedge Transactions. The Warrants expire in August 2026. If the market value per share of the Company's common stock, as measured under the Warrant Transactions, exceeds the strike price of the Warrants, the Warrants will have a dilutive effect on the Company's earnings per share, unless the Company elects, subject to certain conditions, to settle the Warrants in cash. The Warrants meet the criteria in ASC 815-40 to be classified within stockholders' equity, and therefore the Warrants are not revalued after issuance.

Fair Value Measurements	FAIR VALUE MEASUREMENTS Recurring The following table presents the Company's assets and liabilities measured at fair value on a recurring basis at: September 30, 2021 December 31, 2020 (In thousands) Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets Pension plan assets (Note 8) $ 52,123 $ — $ — $ 52,123 $ 61,936 $ — $ — $ 61,936 Liabilities Contingent consideration $ 6,852 $ — $ — $ 6,852 $ 4,609 $ — $ — $ 4,609 Contingent Consideration Related to Acquisitions Liabilities for contingent consideration related to acquisitions were estimated at fair value using management's projections for long-term sales forecasts, including assumptions regarding market share gains and future industry-specific economic and market conditions, and a market participant's weighted average cost of capital. Over the next six years, the Company's long-term sales growth forecasts for products subject to contingent consideration arrangements average approximately 13 percent per year. For further information on the inputs used in determining the fair value, and a roll forward of the contingent consideration liability, see Note 11 of the Notes to Condensed Consolidated Financial Statements. Changes in either of the inputs in isolation would result in a change in the fair value measurement. A change in the assumptions used for sales forecasts would result in a directionally similar change in the fair value liability, while a change in the weighted average cost of capital would result in a directionally opposite change in the fair value liability. If there is an increase in the fair value liability, the Company would record a charge to selling, general and administrative expenses, and if there is a decrease in the fair value liability, the Company would record a benefit in selling, general and administrative expenses.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING The Company has two reportable segments, the OEM Segment and the Aftermarket Segment. Intersegment sales are insignificant. The OEM Segment, which accounted for 81 percent and 77 percent of consolidated net sales for the nine months ended September 30, 2021 and 2020, respectively, manufactures or distributes a broad array of engineered components for the leading OEMs in the recreation and transportation product markets, consisting primarily of RVs and adjacent industries, including buses; trailers used to haul boats, livestock, equipment and other cargo; trucks; boats; trains; manufactured homes; and modular housing. Approximately 62 percent of the Company's OEM Segment net sales for the nine months ended September 30, 2021 were of components for travel trailer and fifth-wheel RVs. The Aftermarket Segment, which accounted for 19 percent and 23 percent of consolidated net sales for the nine months ended September 30, 2021 and 2020, respectively, supplies engineered components to the related aftermarket channels of the recreation and transportation product markets, primarily to retail dealers, wholesale distributors, and service centers. The Aftermarket Segment also includes biminis, covers, buoys, fenders to the marine industry, towing products, truck accessories, and the sale of replacement glass and awnings to fulfill insurance claims. Decisions concerning the allocation of the Company's resources are made by the Company's chief operating decision maker ("CODM"), with oversight by the Board of Directors. The CODM evaluates the performance of each segment based upon segment operating profit or loss, generally defined as income or loss before interest and income taxes.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2021
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, net sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to product returns, sales and purchase rebates, accounts receivable, inventories, goodwill and other intangible assets, net assets of acquired businesses, income taxes, warranty and product recall obligations, self-insurance obligations, operating lease right-of-use assets and obligations, asset retirement obligations, long-lived assets, pension and post-retirement benefits, stock-based compensation, segment allocations, contingent consideration, environmental liabilities, contingencies, and litigation. The Company bases its estimates on historical experience, other available information, and various other assumptions believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other resources. Actual results and events could differ significantly from management estimates.
Recently adopted accounting pronouncement	Recently adopted accounting pronouncement In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity ("ASU 2020-06"). This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. ASU 2020-06 also amends the diluted earnings per share calculation for convertible instruments by requiring the use of the if-converted method. The Company has chosen to early adopt ASU 2020-06 in 2021. This ASU had no retrospective changes but impacted how the convertible debt the Company issued in May 2021 was both recognized and disclosed.
