Fits: 1984-'18 HD^® big twins and 1986-'19 HD^® Sportster^® models. Kit contains 2 front and 2 rear rocker arms. S&S^® now offers an economical solution for stock rebuilds, and mild performance upgrades. S&S^® standard rocker arms are forged from 8620 steel for greater strength than stock forged or cast steel rocker arms. In addition, they feature the same 3/4" long rocker shaft bushings that our S&S^® roller rocker arms do. Thousands of hours of engine testing have proved them to be superior to other non-roller rocker arms. The 3/4" long bronze bushings provide 50% more load bearing area than the 1/2" long bushings used in stock and other aftermarket rocker arms.  New rocker arm shafts are recommended for maximum performance and rocker life. S&S roller rocker arms are recommended for use with cams having more than 0.585" of lift. Adjustable pushrods must be used with S&S roller rocker arms to obtain proper valve clearance. New rocker arm shafts are recommended for maximum performance and rocker life.
