Product Details

This COMP Cams XR281HR hydraulic roller camshaft and lifter kit features a 228/230 degree intake/exhaust duration, a key spec for achieving strong performance in high RPM street and strip applications. It's built for GM LS Gen III and IV engines, fitting a wide range of displacements from 4.8L to 7.0L, including popular models like the Chevrolet Corvette, Camaro, and Silverado. This kit is designed to work well with aftermarket intake manifolds like the FAST LSX and will require an engine programmer to adjust for the new camshaft profile.

Included in this kit are the camshaft itself, a set of high-lift hydraulic roller lifters, assembly lube to ensure proper break-in, and decals. The camshaft's design is optimized for engines running at higher RPMs, making it a solid choice for those looking to extract more power from their LS engine for performance driving. Remember that installing a camshaft of this nature changes the engine's breathing characteristics, so tuning is essential for optimal performance and reliability.

When considering this upgrade, it's important to note that it is not CARB approved and cannot be shipped to California. For a successful installation, always refer to the manufacturer's instructions included in the kit, especially regarding the use of assembly lube and the necessary engine tuning.
