The COMP Cams Ultra Pro Magnum shaft-mount rocker is a 1.5 ratio unit intended for Chrysler LA small-block 273-360 ci V8 applications. Built for shaft-mounted systems, it uses a robust investment-cast chromemoly design, a dedicated oiling system and an adjuster that allows ball-style pushrods. The part is specified to handle higher spring rates and long-term service in shaft-mounted valve-train arrangements.
