The COMP Cams Magnum Roller Rocker Arm for Chevrolet V8 (265–400) and V6 (200–262) applications is a street-focused rocker that raises valve lift without flex. Built from 8620 chromemoly steel with a roller tip, a 3/8" stud and 1.52 ratio, it lowers friction and improves ratio accuracy. Intended for setups under 350 lbs open spring pressure, it claims a 15–30 hp advantage over lesser rockers.
