US Diesel Parts - Chevy / GMC

Chevy / GMC
We've been working with the GM diesels since the introduction of the 5.7L Oldsmobile in the late 70's. We've rebuilt countless DB2 injection pumps since then, and we've helped thousands of 6.5L DS4 owners get their trucks back on the road. GM joined forces with Isuzu and really got with the diesel program in 2001 with the release of the first 6.6L Duramax 6600 LB7. The Duramax LLY followed in 2004, the LBZ in 2006, the LMM in 2007 and the LML in 2011.
