The COMP Cams camshaft kit for LS1 engines is aimed at street/strip use and was developed for compatibility with FAST LSX intake setups. The K-KIT supplies camshaft, lifters, valve springs, retainers, valve locks, valve stem seals, timing chain set, assembly lube (for flat tappet installs), decals and instructions. A proper tune or programmer is required to integrate this cam into the engine.
