Improve Your Valve Train's Durability and Longevity
Comp Cams BSR Max-Lift bolt-in, shaft-mounted rocker systems increase valve train stiffness as well as reducing deflection. These rockers will make your camshaft perform as if it has more lift because more of the lobe lift is transferred to the actual valve.
