The camshafts listed here are all for use in the LS-based engines (4.8L-6.2L).

COMP Cams® has never forgotten that performance is defined by results –both at the track and on the street. We spend thousands of hours working with individuals, teams and companies to ensure that our products provide superior performance and reliability. Whether we’re working with a Pro Stock or Sprint Cup team, or putting thousands of grueling miles on one of our pro touring or street/strip components, we test our products in the same places you do. That’s why we know that every COMP Cams® product will perform to the highest of standards.

COMP Cams® is driven by technology. We employ the industry's largest and most highly trained engineering staff, and the most sophisticated manufacturing processes and test equipment in the world. And because of our wide scope of applications, technologies developed for the highest levels of NASCAR and NHRA will find their way into our products for your street machine, too. The integration of research, engineering and development at COMP Cams® is what we call our “Systems Technology” and it consistently proves itself by out-performing the competition.
