Rollers eliminate thrusting on valves for decreased wear on the valve train. Rocker geometry (1. 640 ratio) is better suited to high lift cams. Bushings are 50% longer than stock, increasing time between rebuilds. Larger surface area on the thrust surfaces reduces wear on the heads. Oil is sprayed directly on the valve springs, reducing potential for breaking a valve due to over heating (stock rockers tend
