1.

I have reviewed this annual report on Form 10-K/A of Dorman Products, Inc. (the “registrant”);

2.

Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report.
