LB7 Duramax engine parts for 2001 to 2004 Chevy Silverado HD and GMC Sierra HD trucks.

The LB7 is the original Duramax, built by GM and Isuzu with a cast iron block, aluminum heads and a Bosch CP3 pump. The bottom end is stout. Most LB7 engine work comes down to injector related repairs, valve cover gaskets, head studs for higher power and fuel filter head leaks.
