COMP Cams HRT Stage 2 Camshafts
COMP Cams HRT Stage 2 camshafts use the newest and most advanced lobe designs in order to produce some of the highest average power and torque available. The "Low Shock Technology" features lobe profiles designed to maximize horsepower while improving stability at higher engine speeds. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. These 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 percent improvement in the effective load bearing area, allowing for much higher loads.
