COMP Cams shaft-mount rocker system for GM L9 engines uses 2024 aluminum rockers and an 8620 hardened steel shaft with 1.7 ratio and factory offsets for LS3 and L92 applications. The shaft design increases mounting stiffness and stabilizes the valve train for improved cam-to-valve transfer. Installation may require valve cover spacers, baffle removal or aftermarket valve covers.
