The latest edition to the High Energy™ series of rocker arms includes all the same benefits as its predecessors and makes an excellent replacement rocker for engine rebuilds with stock or COMP® High Energy Chamshafts™. Nitrided for increased strength and durability, these steel rocker arms are designed for Small Block Chevy applications that require a 1.5 rocker ratio and a 7/16" stud.
All High Energy™ Rocker Arms help eliminate the noise and slop associated with worn or high mileage stock rocker arms. They feature a long slot for higher than stock lift camshafts and are engineered to handle higher spring pressures and hardened pushrods. High Energy™ Rocker Arms are also nitrided to increase hardness, thus improving durability and longevity. They ship with pivot balls and adjusting nuts when necessary for installation.
