LST™ & HRT™ Performance Camshaft Packages take the guesswork out of choosing the best valve train upgrade for your specific engine and desired performance. The Low Shock Technology behind these performance 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  GM LS / LT and Dodge Gen III HEMI Applications. From street performance to race, naturally aspirated or boosted, we have a performance package to fit your application or desired horsepower range.

Choose from Stage 1 and Stage 2 LST™ Packages, and Stage 1 , 2 and 3 HRT™ packages.  Both available as a base Cam Kit (CK-Kit) or a more complete Master Kit (MK-Kit).  CK-Kits.  Click on individual kits to see what is included.
