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 March 31, 2021, the Company operated over 100 manufacturing and distribution facilities located throughout North America and Europe. 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 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

Acquisitions, Goodwill And Other Intangible Assets	ACQUISITIONS, GOODWILL AND OTHER INTANGIBLE ASSETS Subsequent Event Schaudt In April 2021, the Company acquired 100 percent of the equity interests of Schaudt GmbH Elektrotechnik & Apparatebau ("Schaudt"), a leading supplier of electronic controls and energy management systems for the European caravan industry located in Markdorf, Germany. The purchase price was approximately $30.0 million. The purchase price is subject to customary adjustments for cash, working capital, and indebtedness. The results of the acquired business will be included in the Company's OEM Segment. The Company is in the process of determining the fair value of the assets acquired and liabilities assumed for the opening balance sheet, including net working capital, fixed assets, and the fair value of intangible assets. Ranch Hand In April 2021, the Company acquired 100 percent of the equity interests of Kaspar Ranch Hand Equipment, LLC ("Ranch Hand"), a manufacturer of custom bumpers, grill guards, and steps for the automotive aftermarket headquartered in Shiner, Texas. The purchase price was approximately $57.4 million, plus contingent consideration up to $3.0 million. The purchase price is subject to customary adjustments for cash, working capital, and indebtedness. The results of the acquired business will be included in the Company's Aftermarket Segment. The Company is in the process of determining the fair value of the assets acquired and liabilities assumed for the opening balance sheet, including net working capital, fixed assets, and the fair value of intangible assets. Acquisitions Completed During the Three Months Ended March 31, 2021 Wolfpack In March 2021, the Company acquired the business and certain assets of Wolfpack Chassis, LLC ("Wolfpack"), a chassis manufacturer in Kendallville, Indiana to add production capacity. The purchase price was $2.8 million paid at closing. The preliminary purchase price allocation resulted in goodwill of $2.0 million. The accounting for this acquisition is incomplete at March 31, 2021. The purchase price allocation is subject to adjustment for net working capital, fixed asset valuation, and the fair value of intangible assets as additional information is obtained within the measurement period (not to exceed 12 months from the acquisition date). As this acquisition is not considered to have a material impact on the Company's financial statements, pro forma results of operations and other disclosures are not presented. Acquisitions with Measurement Period Adjustments During the Three Months Ended March 31, 2021 Veada In December 2020, the Company acquired 100 percent of the outstanding capital stock of Veada Industries, Inc. ("Veada"), a manufacturer and distributor of boat seating and marine accessories based in New Paris, Indiana.

Holdback payments of $2.3 million were paid during the three months ended March 31, 2021. The remaining holdback payments are recorded in the Condensed Consolidated Balance Sheet in accrued expenses and other current liabilities ($8.2 million) and other long-term liabilities ($1.8 million) at March 31, 2021. The results of the acquired business have been included in the Condensed Consolidated Statements of Income since the acquisition date, primarily in the Company's OEM Segment. As the acquisition of Veada is not considered to have a material impact on the Company's financial statements, pro forma results of operations and other disclosures are not presented. During the three months ended March 31, 2021, the Company adjusted the preliminary purchase price allocation reported at December 31, 2020 to account for updates to net working capital balances and assumptions and estimates related to the fair value of fixed assets. These measurement period adjustments would not have resulted in a material impact on the prior period results if the adjustments had been recognized as of the acquisition date. The purchase price allocation is subject to adjustment for net working capital and the fair value of intangible assets as additional information is obtained within the measurement period (not to exceed 12 months from the acquisition date). Challenger In November 2020, the Company acquired substantially all of the business assets of Challenger Door, LLC ("Challenger"), a leading manufacturer and distributor of branded doors for the RV industry and products for specialty and cargo trailers, based in Nappanee, Indiana. The purchase price was $35.0 million, which included holdback payments of $4.5 million to be paid over the next two years. The holdback payments are recorded in the Condensed Consolidated Balance Sheet in accrued expenses and other current liabilities ($3.5 million) and other long-term liabilities ($1.0 million) at March 31, 2021. The results of the acquired business have been included in the Condensed Consolidated Statements of Income since the acquisition date, primarily in the Company’s OEM Segment. As the acquisition of Challenger is not considered to have a material impact on the Company’s financial statements, pro forma results of operations and other disclosures are not presented. During the three months ended March 31, 2021, the Company adjusted the preliminary purchase price allocation reported at December 31, 2020 to account for updates to net working capital balances and assumptions and estimates related to the fair value of fixed assets. These measurement period adjustments would not have resulted in a material impact on the prior period results if the adjustments had been recognized as of the acquisition date.

Retirement Benefits [Abstract]
Pension Plans	PENSION PLANSThe acquisition of Polyplastic 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 (In thousands) 2021 2020 Net service cost $ (1,109) $ (270) Interest cost (166) (81) Expected return on plan assets 108 50 Administrative charges (71) (22) Net periodic pension cost $ (1,238) $ (323)

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 ($164.7 million, or €140.0 million drawn at March 31, 2021). On December 19, 2019, the Company 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 Acquisition Holdings, Inc. (with its subsidiaries, "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. 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 March 31, 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 March 31, 2021) depending on the Company’s total net leverage ratio. At March 31, 2021, the Company had $2.9 million in issued, but undrawn, standby letters of credit under the revolving credit facility. Availability under the Company’s revolving credit facility was $142.4 million at March 31, 2021. Shelf-Loan Facility On February 24, 2014, the Company 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 March 31, 2021. The net proceeds of the Series B Notes were used to repay the Series A Notes. On November 11, 2019, the Company 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. On March 31, 2020, the Company 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 entered into a Second Amendment to the Shelf-Loan Facility to conform additional covenants to the Amended Credit Agreement. The Shelf-Loan Facility expires on November 11, 2022. 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. General At March 31, 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 March 31, 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 March 31, 2021. The combined remaining availability under the revolving credit facility and the potential additional notes issuable under the Shelf-Loan Facility was $292.4 million at March 31, 2021. The Company believes the availability of $142.4 million under the revolving credit facility under the Amended Credit Agreement, along with its cash flows from operations, are adequate to finance the Company’s anticipated cash requirements for the next twelve months.

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 March 31, 2021, based on the present value of the expected future cash flows using a market participant’s weighted average cost of capital of 13.0 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 three months ended March 31, 2021: (In thousands) Balance at beginning of period $ 4,609 Payments (5) Accretion (a) 56 Net foreign currency translation adjustment (197) Balance at end of the period (b) 4,463 Less current portion in accrued expenses and other current liabilities (2,935) Total long-term portion in other long-term liabilities $ 1,528 (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 March 31, 2021 were $5.6 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. Furrion Receivable At March 31, 2021 and December 31, 2020, the Company had a receivable from Furrion Limited ("Furrion") of $42.7 million and $42.3 million, respectively, recorded for purchases of inventory stock following the termination of the distribution and supply agreement with Furrion. The termination agreement originally required Furrion to make periodic payments throughout 2020 and the first six months of 2021; however, due to the impacts of the COVID-19 pandemic, the Company is currently in negotiations impacting the timing of the repayment of this receivable. Accordingly, the Company has classified $7.8 million of the receivable as long-term, and recorded the receivable at its present value at March 31, 2021 based on the currently proposed payment plan. 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 March 31, 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.

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 10 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 [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 82 percent and 81 percent of consolidated net sales for the three months ended March 31, 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 three months ended March 31, 2021 were of components for travel trailer and fifth-wheel RVs. The Aftermarket Segment, which accounted for 18 percent and 19 percent of consolidated net sales for the three months ended March 31, 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. Decisions concerning the allocation of resources are also based on each segment’s utilization of assets. Management of debt is a corporate function. The accounting policies of the OEM and Aftermarket Segments are the same as those described in Note 2 of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

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.
