COMP Cams shaft-mount rocker kit for Big Block Chevrolet with Brodix Big Duke/Dart Iron Eagle heads combines 2024 aluminum rockers with an 8620 hardened steel shaft to increase stiffness and valve-train stability. The 1.7 ratio rockers position cam force efficiently over the valve, improving power transfer compared with stud-mounted systems and helping the engine resist deflection under load.
