Item 2.02.
Results of Operation and Financial Condition.

The information being furnished in this Item 2.02 and in Exhibit 99.1 shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act except as shall be expressly set forth by specific reference in such filing.

On July 31, 2009, Dorman Products, Inc. (the “Company”) issued a press release announcing its operating results for the second quarter ended June 27, 2009.  A copy of the press release is attached hereto as Exhibit 99.1 and incorporated by reference herein.

Certain statements in this report constitute "forward-looking statements" within the meaning of the Federal Private Securities Litigation Reform Act of 1995.  While forward-looking statements sometimes are presented with numerical specificity, they are based on various assumptions made by management regarding future circumstances over many of which the Company has little or no control.  Forward-looking statements may be identified by words including "anticipate," "believe," "estimate," "expect," and similar expressions.  The Company cautions readers that forward-looking statements, including, without limitation, those relating to future business prospects, revenues, working capital, liquidity, and income, are subject to certain risks and uncertainties that would cause actual results to differ materially from those indicated in the forward-looking statements.  Factors that could cause actual results to differ from forward-looking statements include but are not limited to competition in the automotive aftermarket industry, concentration of the Company's sales and accounts receivable among a small number of customers, the impact of consolidation in the automotive aftermarket industry, foreign currency fluctuations, dependence on senior management and other risks and factors identified from time to time in the reports the Company files with the Securities and Exchange Commission.  Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected.  For additional information concerning factors that could cause actual results to differ materially from the information contained in this report, reference is made to the information in  Part I, "Item 1A, Risk Factors" in the Company's Annual Report on Form 10-K for the fiscal year ended December 27, 2008.
