Accounting Policies [Abstract]	'
Description of Business, Basis of Presentation and Summary of Significant Accounting Policies	'
	Description of the Business, Basis of Presentation and Summary of Significant Accounting Policies
	Fox Factory Holding Corp. (the "Company") designs and manufactures high-performance suspension products primarily for mountain bikes, side-by-side vehicles, on-road and off-road vehicles and trucks, all-terrain vehicles, snowmobiles, specialty vehicles and applications, and motorcycles. The Company acts both as a tier one supplier to leading action sports original equipment manufacturers (“OEM”) and provides aftermarket products to retailers and distributors (“AM”).
	Throughout this Form 10-Q, unless stated otherwise or as the context otherwise requires, the "Company," "FOX," "Fox Factory," "we," "us," "our," and "ours" refer to Fox Factory Holding Corp. and its wholly owned operating subsidiaries on a consolidated basis.
	Basis of Presentation - The accompanying condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K as filed with the SEC. In management’s opinion, the unaudited interim consolidated financial statements reflect all adjustments, which are of a normal and recurring nature, that are necessary for a fair presentation of financial results for the interim periods presented. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	Initial Public Offering- On August 13, 2013, the Company completed the initial public offering (“IPO”) of its common stock pursuant to a registration statement on Form S-1. In the IPO, the Company sold 2,857 shares of common stock and the selling stockholders sold a total of 7,000 shares of common stock (including the shares sold pursuant to the exercise of the option granted to the underwriters) at an initial public offering price to the public of $15.00 per share. The Company received net proceeds from the IPO of approximately $36,122 from its sale of 2,857 shares of common stock after deducting underwriting discounts, commissions and offering expenses. The Company did not receive any proceeds from the sale of shares by the selling stockholders. The Company used the net proceeds it received to pay down related party debt. In July 2014, certain selling stockholders completed a secondary offering of the Company's common stock, which is described more fully in Note 8 - Stockholders' Equity.
	Principles of Consolidation- These condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. The Company’s subsidiaries include: Fox Factory, Inc, ST USA Holding Corp. and Fox Factory GmbH. All intercompany accounts and transactions have been eliminated in consolidation.
	Summary of Significant Accounting Policies- There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 that have had a material impact on our condensed consolidated financial statements and related notes.
	Use of Estimates- The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management’s estimates.
	In the second quarter of 2014, the Company concluded an analysis of legal developments and business practices relative to the apportionment of income for state tax purposes that resulted in a change in estimate regarding income taxes. See Note 10 - Income Taxes.
	Certain Significant Risks and Uncertainties- The Company is subject to those risks common in manufacture-driven markets, including, but not limited to, competitive forces, dependence on key personnel, customer demand for its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed.
	Recent Accounting Pronouncements- In May 2014, the Financial Accounting Standards Board ("FASB") and International Accounting Standards Board issued their converged standard on revenue recognition, Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers". This standard outlines a single comprehensive model for companies to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that revenue is recognized when a customer obtains control of a good or service. A customer obtains control when it has the ability to direct the use of and obtain the benefits from the good or service. Transfer of control is not the same as transfer of risks and rewards, as it is considered in current guidance. We will also need to apply new guidance to determine whether revenue should be recognized over time or at a point in time. This standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016, with no early adoption permitted, and the Company can choose to apply this standard retrospectively for each prior reporting period presented or retrospectively with the cumulative effect of initially applying the standard recognized at the date of the initial application in retained earnings.
	Reclassifications- We have reclassified certain prior period amounts within our condensed consolidated statement of cash flows for the six months ended June 30, 2013 to conform to our current year presentation.

	2013 Credit Facility Amended and Restated
	In August 2013, the Company entered into a credit facility with Sun Trust Bank and other named lenders (the "2013 Credit Facility"). The 2013 Credit Facility provided a revolving line of credit. On March 31, 2014, in connection with its asset purchase of Sport Truck, the Company amended and restated the 2013 Credit Facility (the “Amended and Restated 2013 Credit Facility”). The Amended and Restated 2013 Credit Facility provides a maturing secured term loan in the principal amount of $50,000, subject to quarterly principal payments, and extends the term of the 2013 Credit Facility through March 31, 2019. The proceeds of the term loan were used, in part, to fund the acquisition of Sport Truck and to pay down the revolving line of credit provided under the 2013 Credit Facility of $5,000.
	The Amended and Restated 2013 Credit Facility provides for interest at either a rate based on the London Interbank Offered Rate, or LIBOR, plus a margin ranging from 1.50% to 2.50%, or based on the prime rate offered by SunTrust Bank plus a margin ranging from 0.50% to 1.50%. At June 30, 2014 the one month LIBOR and prime rates were 0.015% and 3.25%, respectively. The Amended and Restated 2013 Credit Facility is secured by substantially all of the Company’s assets, restricts the Company's ability to make certain payments and engage in certain transactions, and also requires that the Company satisfy customary financial ratios. The Company was in compliance with the covenants as of June 30, 2014.
	The following table summarizes the line of credit under the Amended and Restated 2013 Credit Facility:

Commitments and Contingencies	'
	Commitments and Contingencies
	Operating Leases—The Company has operating lease agreements for office, research and development, manufacturing and sales and marketing space that expire at various dates. The Company recognizes rent expense on a straight-line basis over the lease term and records the difference between cash rent payments and the recognition of rent expense as a deferred rent liability.
	Indemnification Agreements—In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners, and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. While the outcome of these matters cannot be predicted with certainty, the Company does not believe that the outcome of any claims under indemnification arrangements will have a material effect on the Company’s results of operations, financial position or liquidity.
	Other Commitments—In connection with our acquisition of Sport Truck, we have agreed to pay up to $29,295 in additional consideration through 2017, contingent upon the achievement of certain financial performance goals through 2016. See Note 13 - Acquisition. No other material contractual obligation has changed since the Company's Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the SEC on March 11, 2014.

	Secondary Offering
	In July 2014, selling stockholders, including Compass Group Diversified Holdings LLC, sold 5,750 shares of our common stock at a price of $15.50 per share, less underwriting discounts and commissions, in a secondary public offering. The total shares sold include 750 shares, which were also sold by certain selling stockholders, in connection with the underwriters' option to purchase additional shares. The Company did not sell or receive any proceeds from the sales of shares by the selling stockholders. The Company incurred approximately $400 of expenses in connection with the offering during the three and six months ended June 30, 2014.
	Equity Incentive Plans
	During the six months ended June 30, 2014, 421 shares of common stock were issued due to the exercise of stock options, resulting in net proceeds to the Company of approximately $1,750.  There were no stock options granted during the six months ended June 30, 2014.  There were 19 stock options forfeited during the six months ended June 30, 2014 .
	The following table summarizes the activity for the Company’s unvested restricted stock units ("RSU") for the six months ended June 30, 2014:
		Unvested RSUs
		Number of shares outstanding		Weighted-average grant date fair value
	Unvested at December 31, 2013	516		$	17.53
	Granted	392		17.09
	Vested	(5	)	17.53
	Unvested at June 30, 2014	903		$	17.34
	The fair value of the RSUs granted is determined using the fair value of the Company’s common stock on the date of grant. Stock-based compensation expense is amortized on a straight-line basis over the requisite service period. As of June 30, 2014, the Company had approximately $13,374 of unrecognized stock-based compensation expense related to RSUs, which will be recognized over the remaining weighted-average vesting period of approximately 3.42 years. Additionally, as of June 30, 2014, the Company had approximately $947 of unrecognized stock-based compensation expense related to stock options, which will be recognized over the remaining weighted-average vesting period of approximately 2.73 years.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	The FASB's Accounting Standards Codification 820, "Fair Value Measurements and Disclosures" requires the valuation of assets and liabilities required or permitted to be either recorded or disclosed at fair value based on hierarchy of available inputs as follows:
	Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
	Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets and liabilities in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
	Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).
	As of June 30, 2014, the carrying amount of the principal under the Company’s Amended and Restated 2013 Credit Facility approximates fair value because it has a variable interest rate that reflects market changes in interest rates and changes in the Company’s net leverage ratio. As of June 30, 2014, the Company used Level 2 inputs to determine the fair value of its Amended and Restated 2013 Credit Facility.
	The Company measured its contingent consideration liability of $19,035 arising from the acquisition of Sport Truck using Level 3 unobservable inputs (see Note 13 - Acquisition). The fair value of the contingent consideration liability associated with the achievement of adjusted EBITDA targets was estimated by applying a Black-Scholes model to the Company's financial projection.  The unobservable inputs to the valuation model that have the most significant effect on the estimated fair value of the Company's contingent consideration liability are the probabilities that actual results will exceed the projection and the volatility surrounding the expected results.  The Company estimated these inputs at 75% and 41%, respectively. There were no adjustments to the fair value of contingent consideration in the three months ended June 30, 2014, as the Company finalized its valuation in July 2014. The fair value of the contingent consideration will be measured at each period end. Future changes in the fair value of contingent consideration resulting from changes in estimates or actual payments will be recorded in the statement of operations.

	For the three and six months ended June 30, 2014, the difference between the Company's effective tax rate and the 35% federal statutory rate resulted primarily from a second quarter discrete tax benefit of $3,848, or $0.10 per basic and fully diluted share for the three months ended June 30, 2014 and $0.11 and $0.10 per basic and fully diluted share, respectively, for the six months ended June 30, 2014, related to the reapportionment of income amongst the jurisdictions where the Company does business. The Company periodically evaluates opportunities to enhance tax efficiencies and to minimize tax liabilities through operating, legal and administrative strategies.  The reapportionment benefit relates to tax years 2009 through 2013 and resulted from the Company's examination of evolving laws, existing court cases, and it's business practices. The tax benefit includes the impact of a reduction in the rate used to measure the Company's net deferred tax liability and unrecognized tax benefit. The benefit has been accounted for as a change in estimate. The Company anticipates filing amended state tax returns in the affected jurisdictions. Additionally, the Company recorded a benefit for the domestic production activity deduction. In the three and six months ended June 30, 2014, these income tax benefits were partially offset by 2014 state taxes.
	For the three and six months ended June 30, 2013, the difference between the Company's effective tax rate and the 35% federal statutory rate resulted from state taxes, partially offset by a benefit for the domestic production activity deduction and research and development tax credits.  On January 3, 2013, the American Taxpayer Relief Act of 2012 was signed into law reinstating the federal research and development credit for the 2012 and 2013 years. Accordingly, the benefit related to the 2012 federal research and development credit of approximately $440 was recorded in the first quarter of 2013 as a discrete item. The benefit related to 2013 research activities was included in the full year effective tax rate. There was no federal research and development credit for the three and six months ended June 30, 2014.
	The following table summarizes the activity related to the Company's unrecognized tax benefits (in thousands):
	Beginning balance as of December 31, 2013	$	7,796
	Increases related to current year tax positions	269
	Decrease due to change in estimated state tax rate	(381		)
	Ending balance as of June 30, 2014	$	7,684
	As of June 30, 2014, the Company had $7,684 of unrecognized tax benefits, of which approximately $6,000, if recognized, would favorably impact the effective tax rate. The Company regularly engages in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. The Company believes it is reasonably possible that certain federal, foreign, and state tax matters may be concluded in the next 12 months. Specific positions that may be resolved include issues involving the deductibility of amortization and depreciation deductions which were incurred as a result of the acquisition of the Company in 2008. The Company estimates that it is reasonably possible that the unrecognized tax benefits at June 30, 2014 could be reduced by approximately $1,700 in the remaining six months of 2014.

Earnings Per Share	'
	Earnings Per Share
	Basic earnings per share ("EPS") amounts are computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. Diluted EPS amounts are computed by dividing net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. Potentially dilutive common shares include shares issuable upon the exercise of outstanding stock options and restricted stock units, which are reflected in diluted earnings per share by application of the treasury stock method.
	The following table presents the calculation of basic and diluted earnings per share:

	Acquisition
	Sport Truck, USA, Inc.
	On March 31, 2014, the Company acquired certain assets and assumed certain liabilities of Sport Truck USA, Inc. (“Sport Truck”). The transaction was accounted for as a business combination. In connection with the acquisition, the Company paid cash of $40,770, after certain working capital adjustments, in accordance with the asset purchase agreement. Certain members of Sport Truck’s executive management team have agreed to refund up to $1,432 of the proceeds from the sale, on a graduated basis, if they terminate employment prior to March 31, 2017. As a result, such payments have been excluded from the acquisition consideration, and will be recognized as compensation expense over the expected three year service period. As of June 30, 2014, prepaid compensation of $487 and $824 is included in prepaids and other current assets and other assets, respectively, in the accompanying condensed consolidated balance sheet.
	Prior to the acquisition, Sport Truck was a distributor of the Company’s products. The total consideration was increased by the effective settlement of trade receivables in the amount of $473, which represented the recorded amount and as a result, no gain or loss was recorded upon settlement.
	The Company agreed to contingent consideration of up to $29,295 upon achievement of adjusted earnings before interest, taxes, depreciation and amortization ("EBITDA") targets of the acquired business through 2016, subject to adjustments defined in the asset purchase agreement. Performance compared to the targets is measured annually over a three year period, and payment of the contingent consideration will be made upon final determination of the adjusted EBITDA for each year. The estimated fair value of the contingent consideration was $19,035, based on a Black-Scholes model. See Note 9 - Fair Value Measurements.
	The purchase price of Sport Truck is allocated to the assets acquired and liabilities assumed based on their estimated respective fair values as of March 31, 2014 with the excess purchase price allocated to goodwill. The Company’s allocation of the purchase price to the net tangible and intangible assets acquired and liabilities assumed is as follows:
	Acquisition consideration
	Cash consideration	$	40,770
	Settlement of pre-existing accounts	473
	Contingent consideration	19,035
	Total consideration at closing	$	60,278
	Fair Market Values
	Other current and non-current assets	$	10,534
	Property, plant and equipment	4,488
	Customer relationships	19,000
	Trademarks and brands	16,270
	Goodwill	11,962
	Total assets acquired	62,254
	Accounts payable and accrued expenses	1,976
	Total liabilities assumed	1,976
	Purchase price allocation	$	60,278
	The values assigned to the identifiable intangible assets were determined by discounting the estimated future cash flows associated with these assets to their present value. The goodwill of $11,962 reflects the strategic fit of Sport Truck with the Company’s operations. Sport Truck is well-aligned with the Company’s mission of improving vehicle performance, delivering best in-class service, and entering into strategic and adjacent markets. The Company will amortize the acquired customer relationships asset over its expected useful life of 15 years. Trademarks, brand names and goodwill are expected to have an indefinite life, and will be subject to impairment testing. The goodwill is expected to be deductible for income tax purposes.
	The Company incurred $222 and $1,247 of transaction costs in conjunction with the Sport Truck acquisition for the three and six months ended June 30, 2014, respectively, which is included in general and administrative expense in the accompanying condensed consolidated statements of income. Additional costs of $278 were incurred in association with financing the transaction and are included in loan fees. See the Note 6 - Debt.
	The following unaudited pro forma financial information shows the combined results of operations of the Company and Sport Truck, as if the acquisition had occurred as of the beginning of the periods presented. The pro forma results include the effects of the elimination of intercompany sales and profits, the amortization of purchased intangible assets and acquired inventory valuation step-up, interest expense on the term debt secured to finance the acquisition, and the net tax benefit of the above adjustments calculated at the statutory federal tax rate of 35%. Sport Truck was operated as a S Corporation for federal taxation purposes. A pro forma adjustment has been made to reflect the income taxes that would have been recorded at the federal statutory rate based on Sport Truck’s net income. This pro forma data is presented for informational purposes only and does not purport to be indicative of the results of future operations or of the results that would have occurred had the acquisition taken place in the periods noted below.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation - The accompanying condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K as filed with the SEC. In management’s opinion, the unaudited interim consolidated financial statements reflect all adjustments, which are of a normal and recurring nature, that are necessary for a fair presentation of financial results for the interim periods presented. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
Principles of Consolidation	'
	Principles of Consolidation- These condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. The Company’s subsidiaries include: Fox Factory, Inc, ST USA Holding Corp. and Fox Factory GmbH. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	'
	Use of Estimates- The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management’s estimates.
Certain Risks and Uncertainties	'
	Certain Significant Risks and Uncertainties- The Company is subject to those risks common in manufacture-driven markets, including, but not limited to, competitive forces, dependence on key personnel, customer demand for its products, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed.
Reclassifications	'
	Reclassifications- We have reclassified certain prior period amounts within our condensed consolidated statement of cash flows for the six months ended June 30, 2013 to conform to our current year presentation.
