COMP Cams Lifter CB Gen6 8.1 OE Hydraulic Roller

With a .842" diameter, these COMP Cams OE-style hydraulic roller lifters are built to replace stock roller lifters in Chevrolet GEN VI Big Block and 8.1L engines originally equipped with roller cams from 1996 onward. They offer a significant improvement over traditional flat tappet lifters by reducing friction, which helps increase their lifespan and allows for more aggressive camshaft profiles.

Each lifter weighs 121g and has a seat height of 2.66", ensuring they fit right into your engine's existing setup. This design is a solid option for anyone rebuilding or upgrading their engine, providing a well-built component that contributes to smoother operation and better performance compared to older flat tappet designs.

These lifters are designed for a range of Chevrolet and GMC trucks and SUVs, including models like the 2002-2006 Chevrolet Avalanche 2500 and the 2001-2006 GMC Sierra 2500 HD. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
