COMP Cams Camshaft Kit CBVI XR308HR-12

This COMP Cams XR308HR-12 Hydraulic Roller Camshaft Kit is built around a camshaft featuring 254 degrees of intake duration and 260 degrees of exhaust duration at .050 inch lift. This specific camshaft profile, combined with the kit's components, is well-suited for high-compression engines, particularly those running 10:1 or higher, and is recommended for applications like jet boats with B impellers, river drags, or bracket racing. It's designed for Chevrolet Big Block GEN VI engines, fitting a range of vehicles including the Chevrolet C2500 Suburban and GMC Savana 3500 from 1996-1999.

When you choose this K-Kit, you're getting a complete package to ensure a proper and efficient camshaft installation. It includes the camshaft itself, hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. To help with the installation process, the kit also comes with a timing chain set and assembly lube, which is particularly useful for flat tappet applications, though this kit features hydraulic roller components. You'll also find decals and detailed instructions to guide you through the process.

This kit is a solid option for those looking to significantly upgrade their Big Block Gen VI engine's performance for racing or high-demand marine use. The extended description notes its effectiveness in jet boats with B impellers and for river drags or bracket racing, indicating its capability for sustained high-RPM operation. Remember that this part is not CARB approved and cannot be shipped to California.
