COMP Cams Cam & Lifter Kit CS XR264HR-1

This COMP Cams Xtreme Energy hydraulic roller camshaft and lifter kit is built around a 212/218 degree intake/exhaust duration profile, a specific design choice that helps it deliver improved mid-range torque without sacrificing too much low-end grunt. It’s intended for mild performance applications where you want a noticeable, but not overwhelming, idle and a solid boost in power through the middle of the RPM range. This kit is designed to work with factory roller camshaft setups on Small Block Chevrolet engines from 1987 and newer, fitting a wide variety of vehicles like the Chevrolet Camaro, Corvette, and C1500 trucks.

Inside this kit, you'll find everything needed to get the new cam and lifters installed and running. It includes the camshaft itself, a set of hydraulic roller lifters that reduce friction and wear compared to flat tappet designs, assembly lube to ensure proper break-in, and decals for your engine bay. The camshaft features a 110-degree lobe separation angle, which contributes to its slightly noticeable idle and strong mid-range pull, making it a popular choice for street-driven vehicles that see regular use. For optimal performance with this cam profile, COMP Cams suggests using rear axle gear ratios between 3.23 and 3.73.

When installing this kit, it’s important to follow the included instructions carefully, especially regarding the use of the assembly lube. This helps protect the new components during the critical initial startup period. While this kit offers a significant performance improvement for your Small Block Chevy, it is not CARB approved and cannot be shipped to California. Ensure your engine is equipped with the factory roller camshaft provisions to properly utilize this upgrade.
