Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Valve stem seals are designed to prevent the mixture of air and oil within your vehicle's combustion chamber. Over time, your vehicle's valve stem seals can wear out and your vehicle will begin to burn oil. If your vehicle is burning oil or you are rebuilding your engine, we recommend replacing your valve stem seals.

For more than 35 years, the COMP Cams mission has never changed: to produce the highest-performing products possible, provide customers with superior service, and to lead the industry in technological development. While the COMP Performance Group has grown to multiple companies and hundreds of employees, we still retain the competitive spirit and desire to be the very best that has positioned COMP Cams as the absolute leader in valve train components.

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.
