Item 4.01. Changes in Registrant’s Certifying Accountant.

Sun Hydraulics Corporation (“the Company”) appointed Mayer Hoffman McCann P.C. – KRMT Tampa Bay Division as the Company’s new auditor as approved by the Audit Committee of the Board of Directors on December 3, 2010. The Company was notified that the shareholders of Kirkland, Russ, Murphy & Tapp, P.A. (“KRMT”), the independent registered public accounting firm engaged by the Company on April 13, 2010, became shareholders of Mayer Hoffman McCann P.C. pursuant to an asset purchase agreement effective November 1, 2010. KRMT now operates under the name Mayer Hoffman McCann P.C.

During the Company’s two most recent fiscal years ended January 2, 2010, and through the date of this Current Report on Form 8-K, the Company did not consult with Mayer Hoffman McCann P.C. regarding any of the matters or reportable events set forth in Item 304 (a)(2) (i) and (ii) of Regulation S-K.

The audit reports of KRMT on the consolidated financial statements of the Company as of, and for the year ended January 2, 2010, did not contain an adverse opinion or a disclaimer of opinion, and were not qualified, or modified, as to uncertainty, audit scope or accounting principles.

In connection with the audits of the Company’s consolidated financial statements for each of the fiscal years ended January 2, 2010, and December 27, 2008, and through the date of this Current Report on Form 8-K, there were (i) no disagreements between the Company and KRMT on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of KRMT, would have caused KRMT to make reference to the subject matter of the disagreement in their reports on the Company’s financial statements for such years, or for any reporting period, since the Company’s last fiscal year end and (ii) no reportable events within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided KRMT a copy of the disclosures in the Form 8-K and has requested that KRMT furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not KRMT agrees with the Company’s statements in this Item 4.01. A copy of the letter dated December 3, 2010, furnished by KRMT in response to that request is filed as Exhibit 16.1 to this Current Report on Form 8-K.
