PROXY STATEMENT

     This Proxy Statement is furnished by the Board of Directors of Sun Hydraulics Corporation (the “Company”) in connection with the solicitation of proxies to be voted at the Company’s 2006 Annual Meeting of Shareholders, which will be held on Tuesday, June 13, 2006, at 2:00 p.m., Eastern Daylight Savings Time, at the Company’s manufacturing facility, located at 701 Tallevast Road, Sarasota, Florida 34243 (the “Meeting”).

     Any proxy delivered pursuant to this solicitation may be revoked, at the option of the person executing the proxy, at any time before it is exercised by delivering a signed revocation to the Company, by submitting a later-dated proxy, or by attending the Meeting in person and casting a ballot. If proxies are signed and returned without voting instructions, the shares represented by the proxies will be voted as recommended by the Board of Directors.

     The cost of soliciting proxies will be borne by the Company. In addition to the use of the mails, proxies may be solicited personally or by telephone by regular employees of the Company. The Company does not expect to pay any compensation for the solicitation of proxies, but may reimburse brokers and other persons holding stock in their names, or in the names of nominees, for their expense in sending proxy materials to their principals and obtaining their proxies. The approximate date on which this Proxy Statement and enclosed form of proxy first has been mailed to shareholders is May 5, 2006.

     The close of business on April 7, 2006, has been designated as the record date for the determination of shareholders entitled to receive notice of and to vote at the Meeting. As of April 7, 2006, 10,933,889 shares of the Company’s Common Stock, par value $.001 per share, were issued and outstanding. Each shareholder will be entitled to one vote for each share of Common Stock registered in his or her name on the books of the Company on the close of business on April 7, 2006, on all matters that come before the Meeting. Abstentions will be counted as shares that are present and entitled to vote for purposes of determining whether a quorum is present. Shares held by nominees for beneficial owners will also be counted for purposes of determining whether a quorum is present if the nominee has the discretion to vote on at least one of the matters presented, even though the nominee may not exercise discretionary voting power with respect to other matters and even though voting instructions have not been received from the beneficial owner (a “broker non-vote”). Abstentions and broker non-votes are not counted in determining whether a proposal has been approved.

ELECTION OF DIRECTORS

     The Board of Directors of the Company currently consists of nine members. The Board is divided into three classes of Directors serving staggered three-year terms. Directors hold their positions until the annual meeting of shareholders in the year in which their terms expire, and until their respective successors are elected and qualified or until their earlier resignation, removal from office or death.

     The term of office of three of the Company’s current nine Directors, Allen J. Carlson, John Kahler and Robert E. Koski, will expire at the Meeting. The Nominating Committee of the Board of Directors has selected each of such Directors as nominees to stand for reelection to the Board at the Meeting.

     Shareholders may vote for up to three nominees for the class of Directors who will serve until the Company’s annual meeting in 2009. If a quorum is present at the meeting, Directors will be elected by a plurality of the votes cast. Shareholders may not vote cumulatively in the election of Directors. In the event any of the nominees should be unable to serve, which is not anticipated, the proxy committee, which consists of Clyde G. Nixon and David N. Wormley, will vote for such other person or persons for the office of Director as the Nominating Committee of the Board of Directors may recommend.

     The Board of Directors unanimously recommends that you vote “FOR” the reelection of Messrs. Carlson, Kahler and Koski to serve until the Company’s annual meeting in 2009. Executed proxies in the accompanying form will be voted at the Meeting in favor of the election as directors of the nominees named above, unless authority to do so is withheld.

Independence and Committees of the Board of Directors

     Independence of Directors. At its meeting in March 2005, and again in March 2006, the Board undertook a review of Director independence and considered transactions and relationships between each Director or any member of his or her immediate family and the Company and its subsidiaries and affiliates, including those reported under “Certain Relationships and Related Transactions.” The purpose of this review was to determine whether any relationships or transactions were inconsistent with a determination that a Director is independent within the meaning of the rules of the Nasdaq Stock Market and, for audit committee members, also independent within the meaning of the rules of the Securities and Exchange Commission. The Board determined that a majority of the Directors of the Company (Messrs. Bertoneche, Kahler, Megerlin, Sakamoto and Wormley) qualify as independent and that none of them has any material relationship with the Company that might interfere with the exercise of his independent judgment.

     The Board of Directors has the standing committees listed below.

Audit Committee.

     The Audit Committee, which consists of John Kahler, Ferdinand Megerlin, and Marc Bertoneche, held nine meetings in 2005. The Board of Directors has determined, under applicable SEC and NASDAQ rules, that all of the members of the Audit Committee are independent and that Dr. Bertoneche meets the qualifications as an Audit Committee Financial Expert and he has been so designated. The functions of the Audit Committee are to select the independent public accountants who will prepare and issue an audit report on the annual financial statements of the Company, to establish the scope of and the fees for the prospective annual audit with the independent public accountants, to review the results thereof with the independent public accountants, to review and approve non-audit services of the independent public accountants, to review compliance with existing major accounting and financial policies of the Company, to review the adequacy of the financial organization of the Company, to review and discuss with management and the Company’s independent accountants their reviews and reports on the effectiveness of the Company’s internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act, to review compliance with federal and state laws relating to accounting practices and to review and approve transactions, if any, with affiliated parties. The Audit Committee also is responsible for review of management’s monitoring of the Company’s compliance with its code of ethics and the periodic review and update of the code. The code of ethics is available on the Investor Relations page of our Web site www.sunhydraulics.com and from the Company upon written request sent to Corporate Secretary, 1500 West University Parkway, Sarasota, Florida 34243.

     The Audit Committee is governed by a written charter approved by the Board of Directors. The charter is available on the Investor Relations page of our Web site www.sunhydraulics.com and from the Company upon written request sent to the Corporate Secretary, 1500 West University Parkway, Sarasota, Florida 34243.

Compensation Committee.

     The Compensation Committee, which consists of David Wormley, Ferdinand Megerlin, and John Kahler, reviews, approves and recommends to the Board of Directors the terms and conditions of all employee benefit plans or changes thereto, administers the Company’s restricted stock and stock option plans and carries out the responsibilities required by the rules of the Securities and Exchange Commission. The Committee met four times during 2005.

     The Compensation Committee is governed by a written charter approved by the Board of Directors. The charter is available on the Investor Relations page of our Web site www.sunhydraulics.com and from the Company upon written request sent to the Corporate Secretary, 1500 West University Parkway, Sarasota, Florida 34243.

Nominating Committee.

     The Nominating Committee, which consists of John Kahler, Hirokatsu Sakamoto, and David Wormley held four meetings in 2005. The Nominating Committee is responsible for identifying individuals qualified to become members of the Board of Directors, consistent with criteria approved by the Board, and for selecting the director nominees to stand for election at each annual meeting of shareholders.

     In March 2004, the Board adopted a Statement of Policy Regarding Director Nominations, setting forth qualifications of Directors, procedures for identification and evaluation of candidates for nomination, and procedures for recommendation of candidates by shareholders. As set forth in the Statement of Policy, a candidate for Director should meet the following criteria:

	•		must, above all, be of proven integrity with a record of substantial achievement;
	•		must have demonstrated ability and sound judgment that usually will be based on broad experience;
	•		must be able and willing to devote the required amount of time to the Company’s affairs, including attendance at Board and committee meetings and the annual shareholders’ meeting;
	•		must possess a judicious and somewhat critical temperament that will enable objective appraisal of management’s plans and programs; and
	•		must be committed to building sound, long-term Company growth.

     Other than the foregoing, the Board does not believe there is any single set of qualities or skills that an individual must possess to be an effective Director or that it is appropriate to establish any specific, minimum qualifications for a candidate for election as a Director. Rather, the Committee will consider each candidate in light of the strengths of the other members of the Board of Directors and the needs of the Board and the Company at the time of the election.

     The Committee will take whatever actions it deems necessary under the circumstances to identify qualified candidates for nomination for election as a member of the Board of Directors, including the use of professional search firms, recommendations from Directors, members of senior management and security holders. All such candidates for any particular seat on the board shall be evaluated based upon the same criteria, including those set forth above and such other criteria as the Committee deems suitable under the circumstances existing at the time of the election.

     Shareholder recommendations for Nomination as a Director. In order for the Committee to consider a candidate recommended by a shareholder, the shareholder must provide to the Corporate Secretary, at least 120, but not more than 150, days prior to the date of the shareholders’ meeting at which the election of Directors is to occur, a written notice of such security holder’s desire that such person be nominated for election at the upcoming shareholders meeting; provided, however, that in the event that less than 120 days’ notice or prior public disclosure of the date of the meeting is given or made to shareholders, notice by the shareholder to be timely must be received not later than the close of business on the tenth business day following the day on which such notice of the date of the meeting was mailed or such public disclosure was made, whichever first occurs.

     A shareholder’s notice of recommendation must set forth:

(a)

as to each person whom the shareholder proposes be considered for nomination for election as a Director,

	(i)		the name, age, business address and residence address of the person,
	(ii)		the principal occupation or employment of the person during the past five years,
	(iii)		the number of shares of Company common stock beneficially owned by the person,

	(iv)		any other information relating to the person that is required to be disclosed in solicitations for proxies for election of Directors pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended, and
	(v)		the consent of the person to serve as a Director, if so elected; and

(b) as to the shareholder giving the notice

	(i)		the name and record address of shareholder,
	(ii)		the number of shares of Company common stock beneficially owned by the shareholder,
	(iii)		a description of all arrangements or understandings between the shareholder and each proposed nominee and any other person pursuant to which the nominations are to be made, and
	(iv)		a representation that the shareholder intends to appear in person or by proxy at the meeting to nominate the person(s) named.

     The Nominating Committee is governed by a written charter approved by the Board of Directors, and the Statement of Policy Regarding Director Nominations described above. The charter and policy statement are available on the Investor Relations page of our Web site www.sunhydraulics.com and from the Company upon written request sent to the Corporate Secretary, 1500 West University Parkway, Sarasota, Florida 34243.

Director Compensation, Participation and Relationships

     Directors who are not officers of the Company are paid $4,000 for attendance at each meeting of the Board of Directors, as well as each meeting of each Board Committee on which they serve when the committee meeting is not held within one day of a meeting of the Board of Directors. In 2004, the Board of Directors adopted and the shareholders approved the Nonemployee Director Equity and Deferred Compensation Plan (the “Plan”) pursuant to which $1,500 of the $4,000 Director fee is paid in shares of Company stock under the Plan. Directors also may elect under the Plan to receive all or part of the remainder of their fees in Company stock and to defer receipt of their fees until a subsequent year. Directors also are reimbursed for their expenses incurred in connection with their attendance at such meetings.

     The Board of Directors held four meetings during 2005. Each Director attended at least 75% of the meetings of the Board and of each committee of which he or she was a member in 2005.

     The Board of Directors, in March 2004, adopted a policy stating that it is in the best interests of the Company that all Directors and nominees for Director attend each annual meeting of the shareholders of the Company. The policy provides that the Board, in selecting a date for the annual shareholders meeting, will use its best efforts to schedule the meeting at a time and place that will allow all Directors and nominees for election as Directors at such meeting to attend the meeting. The policy further provides that an unexcused absence under the policy should be considered by the Nominating Committee in determining whether to nominate a Director for re-election at the end of his or her term of office. All of the Directors attended last year’s annual meeting of shareholders.

     No family relationships exist between any of the Company’s Directors and executive officers, except that Ms. Koski is the daughter of Mr. Koski. There are no arrangements or understandings between Directors and any other person concerning service as a Director.

Compensation Committee Interlocks and Insider Participation

     None.

Compliance with Section 16(a) of the Securities Exchange Act of 1934

     Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s Directors, officers and holders of more than 10% of the Company’s Common Stock to file with the Securities and Exchange Commission initial reports of ownership and reports of changes in ownership of Common Stock and any other equity securities of the Company. To the Company’s knowledge, based solely upon a review of the forms, reports and certificates filed with the Company by such persons, all of them complied with the Section 16(a) filing requirements in 2005, except the following:

	•		Marc Bertoneche filed late one Form 4 statement reporting the issuance of 3.63 stock units.
	•		Richard J. Dobbyn filed late one Form 4 statement reporting a sale of 4 shares.
	•		John Kahler filed late one Form 4 statement reporting the issuance of 1.36 stock units.

     Equity compensation plans approved by shareholders include the 1996 Stock Option Plan, the 2001 Restricted Stock Plan, the Employee Stock Purchase Plan, and the 2004 Nonemployee Director Equity and Deferred Compensation Plan. All shares to be issued upon exercise in column (a) and the weighted average exercise price in column (b) represent shares issued under the 1996 Stock Option Plan. The number of securities available for future issuance in column (c) were: 382,593 shares under the 1996 Stock Option Plan, 411,931 shares under the Employee Stock Purchase Plan, 156,192 shares under the 2001 Restricted Stock Plan, and 112,327 shares under the 2004 Nonemployee Director Equity and Deferred Compensation Plan.

     The only equity compensation plan not approved by shareholders was the 1999 Stock Award Plan. 4,500 shares were authorized for grant under the 1999 Stock Award Plan, which was approved by the Board of Directors on May 21, 1999. The general purpose of the Plan is to recognize and acknowledge extraordinary contributions of employees through the grant of shares of common stock, thereby providing them with a more direct stake in the future welfare of the Company and encouraging them to continue to demonstrate leadership and commitment to the Company. Subject to supervision by the Board and the provisions of the Plan, the Company’s president has the authority to determine the employees to whom awards shall be granted and the number of shares of common stock to be the subject of each award. As of December 31, 2005, there were 450 shares remaining for future grants, and there were no outstanding options, warrants, or rights associated with this plan.

     In December 2005, the Company’s Board of Directors authorized the repurchase of up to $2.0 million of Company stock, to be completed no later than January 15, 2007. The stock purchases will be made in the open market or through privately negotiated transactions. Market purchases will be made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. The amount of the stock repurchases was set based upon the anticipated number of shares that will be required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2006. As of December 31, 2005, the Company had repurchased 82,500 shares on the open market at an average cost of $18.87 per share. Of the 82,500 shares purchased, 65,000 were retired prior to December 31, 2005.

     Subsequent to December 31, 2005, the Company repurchased 12,700 shares on the open market at an average cost of $19.16 per share. Total purchases under the plan have amounted to $1.8 million.

     In November 2004, the Company’s Board of Directors authorized the repurchase of up to $2.5 million of Company stock, to be completed no later than January 15, 2006. The amount of the stock repurchases was set based upon the anticipated number of shares that were required to fund the Company’s ESOP, and employee stock purchase plan, through fiscal year 2005. The Company purchased 8,700 shares at an average cost of $9.52 per share and 2,700 shares at an average cost of $9.80 per share for the periods ending December 25, 2004 and December 31, 2005, respectively. The stock purchases were made in the open market. Market purchases were made subject to restrictions relating to volume, price and timing in an effort to minimize the impact of the purchases on the market for the Company’s securities. All shares were retired during the year purchased.

     The following Compensation Committee Report and the information under the heading Performance Graph below shall not be deemed incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933 or under the Securities Exchange Act of 1934 (together, the “Acts”), except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under the Acts, or to be “soliciting material” or to be “filed” with the Securities and Exchange Commission or subject to Regulations 14A or 14C or to the liabilities of Section 18 of the Securities Exchange Act of 1934.

COMPENSATION COMMITTEE REPORT

     Pursuant to the Compensation Committee Charter approved by the Board of Directors on March 3, 2001, the Compensation Committee oversees the Company’s compensation program. The goals of the Company’s compensation program are to attract and retain highly qualified management personnel, providing them attractive long-term career opportunities. The Company’s compensation philosophy is to provide its executives with a competitive total compensation package which motivates superior job performance, the achievement of the Company’s business objectives, and the enhancement of shareholder value.

     Compensation of the Company’s executive officers is reviewed annually by the Compensation Committee. Changes proposed for these employees are evaluated and approved by the Compensation Committee on an individual basis. The Company’s general approach to compensating executive officers is to pay cash salaries which generally are competitive within ranges of salaries paid to executives of other manufacturing companies. The Committee sets overall compensation at a level it believes to be fair, based upon a subjective analysis of the individual executive’s experience and past and potential contributions to the Company. To assist in determining appropriate overall compensation, the Compensation Committee reviews information regarding revenues, income, and executive compensation for other public manufacturing companies and for other businesses operating in Florida and the southeast United States. The Committee also considers selected information regarding compensation practices, including employee benefits, from manufacturing companies in other countries in which the Company operates in an effort to ensure that the Company maintains competitiveness locally in all its markets.

     During 2005, the Committee determined that the use of restricted shares for domestic employees under the long-term compensation program implemented in 2003 better satisfied the purposes for which such awards were intended than stock options. Therefore, the only stock options granted during 2005 were 4,498 options to the Company’s Chief Executive Officer. Additionally, the General Manager of the Company’s subsidiary, Sun Hydraulics Limited, was granted an aggregate of 2,978 stock appreciation rights during 2005.

     Stock option grants and restricted stock awards to employees of the Company, including the Chief Executive Officer, are made at the discretion of the Compensation Committee pursuant to the Company’s 1996 Stock Option Plan and 2001 Restricted Stock Plan, respectively. Criteria used by the Compensation Committee in the award of stock options and restricted stock include individual responsibilities and individual performance.

     Section 162(m) of the Internal Revenue Code limits the tax deduction to $1.0 million for compensation paid to a corporation’s key executive officers unless certain requirements are met, including that the compensation qualify as performance-based compensation. While the Compensation Committee may from time to time approve awards which would vest upon the passage of time or other compensation which would not result in qualification of those awards as performance-based compensation, it is not anticipated that compensation realized by any executive officer under any of the Company’s plans now in effect will result in a material loss of tax deductions.
