High Energyâ„¢ 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 Camshaftsâ„¢. 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.\u0026lt;ul\u0026gt;\u0026lt;li\u0026gt;Excellent replacement Rocker arms for engine rebuilds with a stock or High Energy Camshaftâ„¢\u0026lt;\/li\u0026gt;\u0026lt;li\u0026gt;Help to eliminate noise and slop associated with worn or high mileage stock Rocker arms\u0026lt;\/li\u0026gt;\u0026lt;li\u0026gt;Include adjusting nuts and pivot balls where required\u0026lt;\/li\u0026gt;\u0026lt;li\u0026gt;Feature a long slot for higher than stock lift Camshafts\u0026lt;\/li\u0026gt;\u0026lt;li\u0026gt;Nitrided Rocker arms designed for higher spring pressures and hardened Pushrods\u0026lt;\/li\u0026gt;\u0026lt;\/ul\u0026gt;\r\n\u003ch3\u003eAttributes:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eCOMP Cams\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00036584206545\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eAmazon ASIN: \u003c\/b\u003eN\/A\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eC.A.R.B.
