Parts for 2001 - 2004 Chevy GMC Duramax 6.6L LB7 Parts
licking their wounds from the infamous 6.5L debacle, GM dusted themselves
off and 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 huge power and economy gains. If you're feeling the need to smoke the tires at your local drag strip or dominate at the truck pulls, then we can help you out there as well.
