Product Details

This COMP Cams CL54-426-11 kit features a 222/224 degree hydraulic roller camshaft, designed to bring out more power in your GM LS engine, particularly in the mid-range and higher RPMs. It's a well-built package that includes the camshaft, lifters, assembly lube, decals, and instructions, so you have the essentials to get started on the installation. This kit is a popular choice for those looking to enhance the performance of their LS-powered vehicle for street and strip use.

The XFI RPM HI-LIFT design of this camshaft means it has a higher lift profile, allowing for more air and fuel mixture into the cylinders. This translates to improved performance, especially when you're pushing your engine harder. Because this camshaft changes the engine's breathing characteristics significantly, you will need an ECU programmer to adjust the fuel and ignition timing to match the new cam profile. Without proper tuning, the engine won't run correctly and could even be damaged.

This kit is designed to fit a wide range of GM LS engines, including displacements from 4.8L up to 7.0L, found in vehicles like the Chevrolet Camaro, Cadillac CTS, and Chevrolet Silverado. It's important to note that while this kit offers a significant performance upgrade, it is not CARB approved and cannot be shipped to California. Always refer to the included instructions for the most accurate installation guidance.
