Replacement shafts, spacers, stands, bolts and everything else needed to build and maintain the most efficient way to transfer power from the camshaft to the valve. Chrome and hardened steel shafts available. Rigidity of shaft systems add stability to both the cylinder head and the valve tra COMP Cams carries everything you need to build and maintain a Shaft Mount Rocker System. Using COMP Cams Shaft Mount Rocker Systems is one of the most effective ways to increase horsepower. These systems transfer power from the camshaft to the valve by positioning the rocker precisely over the valve. Rather than being mounted on a stud, a horizontal shaft works as the fulcrum, which significantly increases mounting stiffness and valve train stability.
