COMP Cams shaft-mount rocker kit for Chrysler 383–440 Indy heads with shaft oiling uses 2024 aluminum rockers and an 8620 hardened steel shaft to stiffen the valve train. Rated at a 1.5 ratio, this shaft system improves how cam force is delivered to the valves, reducing flex versus stud-mounted rockers and helping the engine preserve valve motion and extract more usable power.
