COMP Cams Camshaft Kit CBVI XR300HR-10

This COMP Cams Xtreme Energy XR300HR-10 camshaft kit is built around a hydraulic roller camshaft with a 248/254 degree duration split. This design is intended for Pro Street applications and bracket racing where significant power gains are the goal. To get the most out of this camshaft, you'll need a solid foundation, including at least 10.5:1 compression, a 3500+ RPM stall torque converter, a very efficient intake manifold, and headers paired with low rear-end gears. This kit is designed for Chevrolet Big Block GEN VI engines, fitting a range of vehicles like the 1996-1999 Chevrolet C2500 Suburban and 1996-2000 GMC Sierra 3500.

The K-Kit designation means this package is comprehensive, including not just the camshaft but also all the necessary supporting components for a complete installation. You'll find high-performance hydraulic roller lifters, valve springs, retainers, and valve locks to handle the increased lift and duration. It also includes valve stem seals for proper sealing, a timing chain set for accurate valve timing, and assembly lube to ensure proper lubrication during initial startup. Decals and detailed instructions are also part of the kit, making the installation process as straightforward as possible for a performance camshaft upgrade.

This camshaft kit is a serious upgrade for those looking to push the performance envelope of their Big Block Chevrolet. It’s important to note that this part is not CARB approved and cannot be shipped to California. Ensure your engine build is prepared for the demands of this high-performance camshaft to unlock its full potential.
