The forgings are designed to eliminate stress points andprovide the strongest, most durable rocker arm possible. An oil passage from the pushrodcup of the rocker arm to the inside of the rocker arm body allows top-end oiling throughthe pushrods when used in conjunction with S&S billet tappet guides and S&S QuickeeAdjustable pushrods. Oiling can also be done through the stock 1966-’84 external oilingsystem. The roller tip reduces valve tip wear and side loading of the valve stem in high liftapplications. S&S roller rocker arms are compatible with S&S billet and stock rocker boxes.Some clearancing may be required when using stock rocker boxes.Fitment• 1966-’84 big twins• P-Series engines• SH-Series enginesFeatures and benefits• 8620 steel heat treated forgings for maximum strength• .750" rocker arm bushing for 50% more load bearing area than stock .500" bushings• Roller tip reduces valve tip wear and side thrusting• 1.5:1 rocker ratio• Oil passage allows top end oiling through pushrods• Compatible with stock or S&S billet rocker boxesFlathead Power ® by S&S ®Rocker Arms and ShaftsFor 1940-’48 OHV Big TwinsThese high quality rocker arms and shafts are the same as we use in the KN-Seriesengines, and fit stock knuckle engines too.
