Chevy / GMC - 2001 - 2004 6.6L Duramax LB7

Factory Replacement and Aftermarket Performance Parts for 2001 - 2004 Chevy GMC Duramax 6.6L LB7 pickup trucks.

GM joined forces with Isuzu in 2001 to release the first 6.6L Duramax LB7 engine featuring the latest in Bosch Common Rail Injector technology. They experienced some injector issues early on, but quickly addressed the problems. The mighty 6.6L Duramax pumped out a respectable 300HP right off the showroom floor. The absence of restrictive emissions on the LB7 allowed owners to get more miles between fill ups than most people thought possible from a 3/4 ton pickup. Most modern diesel engines have great potential for power and economy gains over the factory set up, and the LB7 is no exception. We always like to suggest a cold air intake kit and a free flowing exhaust system to lower EGT's and increase MPG's and power. A good tuner will help you pull those steep hills with ease and also get you some great power and economy gains. We also carry turbochargers as well as LB7 injectors and CP3 pumps to keep your fuel system in shape. If you don't see what you're looking for, then please give us a call!
