S&S, M8 forged roller rockers arm set - 18-23 Softail; 17-23 Touring, Trike 516606 Turn signals with 40mm stemForged from 8620 steel for greater strength. S&S roller rockers are stronger and designed to combat excessive valve thrust and valvetrain wear with higher lifts from . 550" and up to a maximum of . 650" valve lift. The rocker geometry is better suited for higher lift cams and the 50% longer shaft bushings to help increase valvetrain lif. Larger surface area on the thrust surfaces reduces wear on the heads and oil is sprayed directly on the valve
