COMP Cams Alum Rocker Arm Chrysler BB Spec

Built from aluminum, this COMP Cams rocker arm shaft is designed to replace the original shaft in COMP Cams' Chrysler big block aluminum shaft rocker arm systems. Specifically, it's intended as a replacement for the shaft that comes with their Chrysler 383-440 aluminum shaft rocker system. This part is well-suited for a wide range of Chrysler, Dodge, and Plymouth big block engines from the late 1950s through the late 1970s, including popular models like the Chrysler New Yorker, Dodge Charger, and Plymouth Barracuda.

Using aluminum for this component helps reduce overall weight in the valvetrain, which can contribute to improved engine response. The shaft itself is a critical piece for ensuring the rocker arms pivot correctly and maintain consistent valve timing. COMP Cams is known for making well-built engine components, and this rocker arm shaft is no exception, offering a solid option for those rebuilding or upgrading their big block Mopar engine's valvetrain.
