Product Details

This is the COMP Cams CB8 Tri-Power Xtreme camshaft, designed for GM 8.1L engines. If you're looking to get more out of your big block, this hydraulic roller camshaft is built to improve both fuel mileage and overall torque output, giving you a noticeable difference in how your truck or SUV performs. It's a well-built component aimed at drivers who want a practical improvement without sacrificing everyday drivability.

The 'Xtreme' in its name refers to its performance tuning, specifically the 194/206 degree intake/exhaust duration at .050 inch lift. This profile is carefully chosen to balance strong low-end and mid-range torque with improved fuel efficiency, a notable feat for an engine of this size. Being a hydraulic roller design, it also means less friction and wear compared to older flat-tappet cams, contributing to its longevity and efficiency. This camshaft is a solid option for owners of vehicles like the Chevrolet Avalanche 2500, Silverado 2500 HD, or Suburban 2500 from the early to mid-2000s.

When installing a camshaft like this, it's important to follow the manufacturer's recommended procedures closely. This often includes using new lifters, checking valve springs, and ensuring proper break-in. While this camshaft is designed for improved performance and mileage, please be aware that it is not CARB approved and cannot be shipped to California. Always consult the COMP Cams installation instructions for the most accurate guidance.
