Notes: Rocker Arm High Energy Nitrided 1.7 Ratio Chevrolet Big Block w/ 7/16 in. Stud
This nitrided COMP Cams High Energy Steel Stud Mount Rocker Arm designed for Chevy V8 265-400 applications features a 3/8 in. stud diameter and 1.5 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.This rocker has 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 materials surface. This improves both the lubricity and wear resistance of the material.
