Product Details
Xtreme Marine Camshaft/Lifter Kit (CL08-417-8) by COMP Cams®. Xtreme Marine™ -Designed to maximize torque, acceleration and throttle response while providing excellent high RPM horsepower. A faster intake valve opening increases engine vacuum and enhances throttle response. Special intake closing ramps close the valve sooner, providing more cylinder pressure and torque without resulting in excessive valve train noise. Faster ramps achieve maximum velocity sooner, increasing the area under the lift curve and providing maximum horsepower. Smoother exhaust designs allow for a more effective purge of spent gasses from the combustion chamber to further increase horsepower. Feature CRC (Constant Radius of Curvature) technology that ensures durability with aggressive hydraulic roller designs.
