Quality Diesel Parts is a family-owned and operated warehouse distributor of diesel engine parts. We just celebrated its 105th year doing business in the Pacific Northwest and beyond! During this time the Cooper family, originally led by D.I. Cooper, has been proud to serve the logging, trucking, construction, industrial, agricultural, and marine industries with diesel parts from leading manufacturers. The business is now being led by Brian and Ginell Cooper, D.I.’s great grandson and his wife. This dynamic duo is carrying on the tradition of providing customers with only the best parts and excellent customer service.
In fact, their parts inventory is the largest in our region, and features a wide range of options, including engine parts, kits, pumps, gaskets, exhaust manifolds, bushings, cams, fuel components, coolers, valve trains, seals, and much more. In addition to our East Portland storefront, we have an ever-evolving online store. You can search for parts, order, and have us ship them anywhere right from your desk, cab, or back-forty. Don’t see the part? We’re always happy to track anything down for you. So, give us a call at (503) 252-9614, email us, or visit our store today! Be sure to ask for Aaron, our hard-working sales manager. He rounds out our team, and is also a second-generation employee. His father-in-law, Mike, trained him and passed on his thorough knowledge of diesel parts. QDP has you covered! Like us on Facebook to keep up to date on our specials and deals.
