COLMAR, PA--(Marketwire - November 10, 2009) - Dorman Products, Inc. (NASDAQ: DORM) announced the release of its 2009 Service Dealer Guide, Volume 2, featuring over 50 formerly "dealer only" parts now available to the Aftermarket. New in Volume 2 are the highlighted European application parts and replacements for Rust Prone parts.

Those interested in obtaining a free copy of the Service Dealer Guide as well as Dorman's Rust & Euro catalogs can go to www.DormanSDG.com and sign up.

Since its inception, the Dorman® Service Dealer Guide has been successful in increasing awareness of Dorman's "New to the Aftermarket" products and innovative repair solutions among Independent Service Dealers. Dorman will distribute over 600,000 copies of the Service Dealer Guide through its customer base.

The Guide consists of 18 pages packed with dozens of "New to the Aftermarket" parts including Vapor Canister Vent Valves, Ignition Lock Cylinder, Passlock Ignition Switch Case, Watts Linkage Bell Crank, ABS Tone Rings, Electric Steering Position and Torque Sensor, BMW Cup Holder and a Trailer Hitch Plug. The products featured in the Service Dealer Guide were formerly "dealer only" parts now made available to the Aftermarket by Dorman.

Just like with Volume 1, Dorman has made the Guide more accessible with the revamped www.DormanSDG.com, the Guide's companion website where visitors can have instant access to a digital version of the Guide, installation videos and much more.

Mr. Richard Berman, Chairman and Chief Executive Officer, said, "Dorman sales increases continue to be driven by new product growth. This growth is fueled by Dorman's recent new product successes and strong market acceptance of our new product lines and line extensions. Our recent decision to move to a four-month distribution cycle for our Service Dealer Guide, which highlights many of these new products, will help increase awareness of the new items to our customers and end users."
