Description

COMP Cams Shaft Mount Rocker Systems increase horsepower by properly positioning the rocker over the valve, transferring power from the camshaft. A horizontal shaft acts as the fulcrum, significantly increasing mounting stiffness and valvetrain stability compared to stud-mounted rockers. These rockers are constructed from high-strength 2024 aluminum and use an 8620 hardened steel shaft. They are designed using the latest computer technology and field-tested by racing experts.
