The Gen III Hemi market is rapidly expanding, and the HRT Camshaft Series uses the newest and most advanced lobe designs from COMP Cams in order to produce some of the highest average power and torque camshafts available for these engines. The “Low Shock Technology” 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. The new HRT Camshafts receive the Micro Surface Enhancement (MSE) finishing process as a standard feature, which increases strength and performance by reducing surface peak roughness and provides a 250% improvement in the effective load bearing area, allowing for much higher loads. Organized into stages, these new options range from mild to wild! All HRT Stage 1 Camshafts are No Springs Required, which keeps cost down while still providing awesome horsepower increases over stock. Stages 2 and 3 applications work with COMP Cams Beehive and Conical Valve Springs, but COMP Cams is also introducing new HEMI Valve Spring Kits, engineered to produce the most power and RPM of any current options..
