Product Details

This is the COMP Cams XFI XE-R Hydraulic Roller Cam and Lifter Kit, part number CL54-444-11, designed for GM LS GEN III and GEN IV engines. If you're looking to significantly boost the performance of your LS-based engine, especially for street and strip applications where high RPM power is key, this kit is a solid choice. It includes the camshaft, lifters, assembly lube, decals, and instructions, giving you the core components needed for a camshaft upgrade.

The XE-R lobe designs are known for their aggressive profiles, which help to achieve impressive power gains at higher engine speeds. This means you'll feel a noticeable difference when the engine is revving, making it ideal for performance-oriented builds. Because these lobes are designed for maximum airflow and lift, they require custom tuning to properly optimize the engine's fuel and ignition maps. This kit is compatible with a wide range of LS engines, including 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L displacements, found in popular vehicles like the Chevrolet Camaro, Corvette, and Silverado trucks, as well as Cadillac CTS and Escalade models.

When installing this kit, remember that it's intended for high-RPM use and will change the engine's driving characteristics. You'll need to ensure your valvetrain components, like valve springs, are up to the task of handling the increased lift and RPM. The kit comes with assembly lube to help protect the new components during initial startup, which is crucial for the longevity of your new camshaft and lifters. Always refer to the included instructions for the most accurate installation procedures.
