COMP Cams shaft-mount rocker kit for Ford 289–351W Windsor production heads uses 2024 aluminum rockers on an 8620 hardened steel shaft to enhance mounting stiffness and valve-train stability. The 1.6 ratio rockers are tuned to improve the camshaft-to-valve power transfer, offering a more rigid fulcrum than stud-mounted rockers and helping the engine maintain consistent valve motion under load.
