STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION
	The Company’s 2006 Stock Option Plan (“2006 Plan”) provides for the grant of incentive stock options and nonqualified stock options for the purchase of up to an aggregate of 1,125,000 shares of the Company’s common stock by officers, employees and directors of the Company. Under the terms of the plan, incentive stock options may be granted to employees at an exercise price per share of not less than the fair value per common share on the date of the grant (not less than 110% of the fair value in the case of holders of more than 10% of the Company’s voting stock). Nonqualified stock options may be granted at the discretion of the Company’s Board of Directors. The maximum term of an option may not exceed 10 years, and options become exercisable at such times and in such installments as determined by the Board of Directors. No awards have been granted under the 2006 Plan.
	The Company’s 2001 Restricted Stock Plan provides for the grant of restricted stock of up to an aggregate of 928,125 shares of the Company’s common stock to officers, employees, consultants and directors of the Company. Under the terms of the plan, the minimum period before any shares become non-forfeitable may not be less than six months. The 2001 Restricted Stock Plan expired in 2011 and was replaced in September 2011 with the 2011 Equity Incentive Plan (“2011 Plan”). The 2011 Plan provides for the grant of up to an aggregate of 1,000,000 shares of restricted stock, restricted share units, stock appreciation rights, dividend or dividend equivalent rights, stock awards and other awards valued in whole or in part by reference to or otherwise based on the Company’s common stock, to officers, employees and directors of the Company. The 2011 Plan was approved by the Company’s shareholders at the 2012 Annual Meeting. At March 28, 2015, 629,462 shares remained available to be issued through the 2011 Plan. Compensation cost is measured at the date of the grant and is recognized in earnings over the period in which the shares vest. Restricted stock expense for the three months ended March 28, 2015 and March 29, 2014, totaled $683 and $678, respectively.
	The following table summarizes restricted stock activity from December 27, 2014, through March 28, 2015:
		Number		Weighted

	The Company had $4,795 of total unrecognized compensation cost related to restricted stock awards granted under the 2011 Plan as of March 28, 2015. That cost is expected to be recognized over a weighted average period of 1.54 years.
	The Company maintains an Employee Stock Purchase Plan (“ESPP”), in which most employees are eligible to participate. Employees in the United States who choose to participate are granted an opportunity to purchase common stock at 85 percent of market value on the first or last day of the quarterly purchase period, whichever is lower. Employees in the United Kingdom, under a separate plan, are granted an opportunity to purchase common stock at market value, on the first or last day of the quarterly purchase period, whichever is lower, with the Company issuing one additional free share of common stock for each six shares purchased by the employee under the ESPP. The ESPP authorizes the issuance, and the purchase by employees, of up to 1,096,875 shares of common stock through payroll deductions. No U.S. employee is allowed to buy more than $25 of common stock in any year, based on the market value of the common stock at the beginning of the purchase period, and no U.K. employee is allowed to buy more than the lesser of £1.5 or 10% of his or her annual salary in any year. Employees purchased 10,410 shares at a weighted average price of $31.99, and 5,850 shares at a weighted average price of $31.63, under the ESPP during the three months ended March 28, 2015 and March 29, 2014, respectively. The Company recognized $76 and $52 of compensation expense during the three months ended March 28, 2015 and March 29, 2014, respectively. At March 28, 2015, 642,983 shares remained available to be issued through the ESPP and the U.K. plan.
	The Nonemployee Director Equity and Deferred Compensation Plan (the “Plan”) originally was adopted by the Board of Directors and approved by the shareholders in 2004, and amended in 2008. Under the Plan, Directors who were not officers of the Company were paid 375 shares of Company common stock and $3 in cash fees for attendance at each meeting of the Board of Directors, as well as each meeting of each Board Committee on which they served when the committee meeting was not held within one day of a meeting of the Board of Directors. Committee Chairmen received additional fees equal to 25% of normal compensation and the Chairman of the Board was paid twice the amount of normal compensation, with such additional compensation payable in Company common stock. Prior to June 7, 2011, Directors were able to elect under the Plan to receive all or part of their cash fees in Company stock and to defer receipt of their fees until a subsequent year. When so deferred, the shares of stock were converted to deferred stock units. Deferred stock units are treated as liabilities. At March 28, 2015, there were zero deferred stock units outstanding. The Plan has now been terminated, and no further issuance of shares will be made under the Plan.
	In March 2012, the Board reviewed its non-employee director compensation policy and determined that compensating Directors solely in Company stock would further align the interests of the Board and the shareholders. Accordingly, the Board of Directors adopted the Sun Hydraulics Corporation 2012 Nonemployee Director Fees Plan (the “2012 Directors Plan”), which was approved by the shareholders of the Company at its 2012 annual meeting.
	Under the 2012 Directors Plan, as compensation for attendance at each Board meeting and each meeting of each committee of the Board on which he or she serves when the committee meeting is not held within one day of a meeting of the Board, each Nonemployee Director will be paid 500 shares of Common Stock. The Chairman’s fee is twice that of a regular director, and the fee for the chairs of each Board Committee is 125% that of a regular director. The Board has the authority to change from time to time, in any manner it deems desirable or appropriate, the share compensation to be awarded to all or any one or more Nonemployee Directors, provided that, with limited exceptions, such changes are subject to prior shareholder approval. The aggregate number of shares which may be issued during any single calendar year is limited to 25,000 shares. The 2012 Directors Plan authorizes the issuance of up to 270,000 shares of common stock. At March 28, 2015, 218,249 shares remained available for issuance under the 2012 Directors Plan.
	Directors were granted 4,500 and 4,000 shares for the three months ended March 28, 2015 and March 29, 2014, respectively. The Company recognized director stock compensation expense of $178 and $170 for the three months ended March 28, 2015 and March 29, 2014, respectively.

	On March 28, 2015, the Company had restricted cash of $316. A restricted cash reserve for customs and excise taxes in the U.K. operation was $45 at March 28, 2015. The restricted amount was calculated as an estimate of two months of customs and excise taxes for items coming into the Company’s U.K. operations and is held with Lloyds TSB in the U.K. Restricted cash of $271 at March 28, 2015, represents the holdback of the purchase price associated with the acquisition of Seungwon on October 18, 2012.

A valuation of the reporting unit at December 27, 2014 indicated that there was no impairment of the carrying value of the goodwill at Sun Korea. A valuation of the reporting unit at September 27, 2014 indicated that there was no impairment of the carrying value of the goodwill at HCT. As of March 28, 2015, no factors were identified that indicated impairment of the carrying value of goodwill.
	In 2014, the Company entered into a licensing agreement with Sturman Industries, Inc., recognizing intangible assets of $1,075 in 2014 and $575 in the quarter ending March 28, 2015. The agreement is for licensed technology to be used with the Company's electrically actuated hydraulic cartridge valves, and lasts for a period of fifteen years from the date of first sale. The Company recognized $2,658 and $746 in identifiable intangible assets as a result of the acquisitions of HCT and WhiteOak, respectively. Intangible assets are held in other assets on the balance sheet. At March 28, 2015 and December 27, 2014, intangible assets consisted of the following:

	Intangible assets are evaluated for impairment whenever events or circumstances indicate that the undiscounted net cash flows to be generated by their use over their expected useful lives and eventual disposition may be less than their net carrying value. No such events or circumstances occurred during the three months ended March 28, 2015.

Long-term Debt, Unclassified [Abstract]
LONG-TERM DEBT	LONG-TERM DEBT
	Effective August 1, 2011, the Company entered into a credit and security agreement in the U.S. with Fifth Third Bank (the “Bank”). The agreement initially provided for three separate credit facilities totaling $50,000. As noted below, at March 28, 2015, two of the original facilities remain available.
	Facility A is a $15,000 unsecured revolving line of credit and requires monthly payments of interest. Facility A has a floating interest rate of 1.45% over the 30-day LIBOR Rate (as defined).
	Facility B is an accordion feature to increase the revolving line of credit to a $35,000 secured revolving line of credit. Facility B will be secured by the Company’s U.S. assets, including its manufacturing facilities, and requires monthly payments of interest. Facility B will bear interest at the 30-day LIBOR Rate or the Bank’s Base Rate (as defined), at the Company’s discretion, plus a margin based on the Borrower’s Funded Debt to EBITDA Leverage Ratio (as defined). The LIBOR Margin ranges from 1.45% to 2.25% and the Bank’s Base Rate ranges from (0.25)% to 0.00%.
	Facility C is a $15,000 construction and term loan. The Company did not activate Facility C for the construction of its new Sarasota factory and access to this facility is now expired.
	Facility A or Facility B (if activated) is payable in full on August 1, 2016. Maturity may be accelerated by the Bank upon an Event of Default (as defined). Prepayment may be made without penalty or premium at any time upon the required notice to the Bank.
	Facility A is subject to debt covenants (capitalized terms are defined therein) including: 1) Minimum Tangible Net Worth of not less than $92,000, increased annually by 50% of Net Income, and 2) Minimum EBITDA of not less than $5,000; and requires the Company to maintain its primary domestic deposit accounts with the bank. At March 28, 2015, the Company was in compliance with all debt covenants related to Facility A as follows:
	Covenant	Required Ratio/Amount	Actual Ratio/Amount
	Minimum Tangible Net Worth	$170,443	$	194,651
	Minimum EBITDA	Not less than $5 million	$	70,730

	At March 28, 2015, the Company had an unrecognized tax benefit of $1,156 including accrued interest. If recognized, the unrecognized tax benefit would have a favorable effect on the effective tax rate in future periods. The Company recognizes interest and penalties related to income tax matters in income tax expense. Interest accrued as of March 28, 2015, is not considered material to the Company’s consolidated financial statements.
	The Company files U.S. federal income tax returns as well as income tax returns in various states and foreign jurisdictions. The Company is no longer subject to income tax examinations by tax authorities for years prior to 2005 for the majority of tax jurisdictions.
	The Company’s federal returns are currently under examination by the Internal Revenue Service (IRS) in the United States for the periods 2005 through 2012. To date, there have not been any significant proposed adjustments that have not been accounted for in the Company’s consolidated financial statements.
	Audit outcomes and the timing of audit settlements are subject to significant uncertainty. It is reasonably possible that within the next twelve months the Company will resolve some or all of the matters presently under consideration for 2005 through 2012 with the IRS and that there could be significant increases or decreases to unrecognized tax benefits.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS
	The Company applies fair value accounting guidelines for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). Under these guidelines, fair value is defined as the price that would be received for the sale of an asset or paid to transfer a liability (i.e. an exit price) in an orderly transaction between market participants at the measurement date. The guidance establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:
	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.
	Level 3 - Unobservable inputs that are supported by little, infrequent, or no market activity and reflect the Company’s own assumptions about inputs used in pricing the asset or liability.
	The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
	The Company’s valuation techniques used to measure the fair value of marketable equity securities, mutual funds, and phantom stock units were derived from quoted prices in active markets for identical assets or liabilities. The valuation techniques used to measure the fair value of all other financial instruments were valued based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data.
	The Company’s short-term investments have been classified and accounted for as available-for-sale. Management determines the appropriate classification of its investments at the time of purchase and reevaluates the designation at each balance sheet date. The Company may or may not hold securities with stated maturities greater than 12 months until maturity. As management views these securities as available to support current operations, the Company classifies securities with maturities beyond 12 months as current assets under the caption short-term investments in the accompanying Consolidated Balance Sheets. These investments are carried at fair value, with the unrealized gains and losses reported as a component of shareholder’s equity. Realized gains and losses on sales of investments are generally determined using the specific identification method, and are included in miscellaneous (income) expense in the Consolidated Statements of Operations.
	The following tables provide information regarding the Company’s assets and liabilities measured at fair value on a recurring basis at March 28, 2015 and December 27, 2014.

	The Company recognized a net realized loss on investments during the three months ended March 28, 2015 of $8 and a net realized gain of $75 during the three months ended March 29, 2014. As of March 28, 2015, gross unrealized losses related to individual securities that had been in a continuous loss position for 12 months or longer were not significant. The Company considers these unrealized losses in market value of its investments to be temporary in nature. When evaluating an investment for other-than-temporary impairment, the Company reviews factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, and the Company’s intent to sell, or whether it is more likely than not it will be required to sell, the investment before recovery of the investment’s cost basis. There were no other-than-temporary impairments during the three month period ended March 28, 2015.
	Maturities of investments at March 28, 2015 are as follows:
		Adjusted Cost		Fair Value
	Due in less than one year	$	16,910	$	16,792
	Due after one year but within five years	15,395		15,140

	Total	$	44,852	$	43,629
	The Company reports phantom stock units as a liability. The Company recognized expense relating to this liability of $11 and $12, for the three month periods ended March 28, 2015 and March 29, 2014, respectively. Phantom stock units vest over a period of three years.
	The Company did not have any fair value adjustments for assets and liabilities measured at fair value on a nonrecurring basis during the period ended March 28, 2015.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTS
	In August 2014, the FASB issued guidance on Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern. The guidance requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. The guidance applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. The Company does not expect the adoption of this guidance to have a material impact on the Company's consolidated financial statements.
	In May 2014, the FASB issued guidance on Revenue from Contracts with Customers, to clarify the principles used to recognize revenue for all entities. The core principle of the new guidance is that an entity will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The standard provides a five-step analysis of transactions to determine when and how revenue is recognized. Additionally, the guidance requires disaggregated disclosures related to the nature, amount, timing, and uncertainty of revenue that is recognized. The guidance is effective for annual and interim periods beginning after December 15, 2016. The FASB has proposed delaying this standard by one year. If the proposal is approved, early adoption would be permitted as of the original effective date. The Company is currently evaluating the effects, if any, adoption of this guidance will have on the Company’s consolidated financial statements.
