Built for the 6.6L Duramax

From the LB7 to the L5P, the Duramax earns its reputation — but the factory up pipes and exhaust manifolds crack, the motor mounts collapse, and the L5P fuel filter cap splits. We carry the bolt-on hardware that fixes those known weak points and holds up under work and towing.
