COMP Cams Stage 2 LST Camshaft Packages
COMP Cams Stage 2 LST camshaft packages for GM LS applications take the guesswork out of choosing the right valve train upgrade package for your specific engine and desired performance. The "Low Shock Technology" behind COMP Cams LST camshaft packages features lobe profiles designed to maximize horsepower, while improving stability at higher rpm. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. By Spintron and dyno testing these new profiles with many combinations of valve train components, COMP Cams engineers have created valve train packages that are perfectly matched for maximum horsepower and dependability in all popular LS applications with varying modifications. Stage 2 LST kits commonly add 90+ hp, depending on application.
Stage 2 LST camshaft packages include:
* COMP Cams LST Camshaft
* Pushrods
* Valve Springs
* Retainers
* Valve Locks
* Spring Seats
* Valve Seats
