These nitrided COMP Cams® High Energy™ Steel Stud Mount Rocker Arms designed for 1965-87 Chevy 396-454 applications feature a 7/16" stud diameter and 1.7 ratio. High Energy™ Rockers help eliminate the noise and slop associated with older worn and high mileage stock rocker arms. With a long slot for higher than stock lift camshafts, these rocker arms are an excellent replacement choice for engine rebuilds using either stock or High Energy Camshafts™.
These rockers have been nitrided to increase surface hardness for improved initial and long-term wear characteristics. The nitriding process increases hardness by causing an infusion of nitrogen molecules into the material’s surface. This improves both the lubricity and wear resistance of the material.
