COMP Cams shaft-mount rocker kit for SBC with Brodix X heads and select Pontiac applications uses 2024 aluminum rockers on an 8620 hardened steel shaft for improved rigidity and valve-train stability. Featuring 1.6/1.5 ratios, the shaft system positions rocker force efficiently over the valve for superior cam-to-valve transfer compared with stud mounts, helping recover horsepower and resist deflection.
