COMP Cams Engine Rocker Arm Kit 1219-16

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.
