Roller rocker arms for shovelhead engines borrow some features of the S&S rocker arms for later style engines. Like our roller rockers for 1984-up big twins, the S&S rocker arms for shovelhead engines are machined from 4140 steel forgings and heat treated for maximum strength. The forgings are designed to eliminate stress. points and provide the strongest, most durable rocker arm possible. These roller rocker arms also feature the exclusive .750” long S&S rocker arm bushings. The S&S bushings provide 50% more load bearing surface than stock .500” bushings. The final special feature is an oil passage from the pushrod cup of the rocker arm to the inside of the rocker arm body that allows top end oiling through the pushrods when used in conjunction with S&S billet tappet guides and Quickee pushrods. Oiling can also be done through the stock 1966-’84 external oiling system. S&S roller rocker arms for shovelhead engines have a nominal rocker ratio of 1.5:1, and high precision CNC machining insures that this ratio will be consistent in all parts. Our experience has shown that the actual rocker ratio of stock and aftermarket rocker arms can vary widely. Some are less than the nominal stock 1.43:1 ratio and some are more. The roller tip reduces valve tip wear and side loading of the valve stem in high lift applications. 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. Fits 1966 - ' 84 Harley-Davidson® shovelhead engines.
