  • Roller Rocker Arm Set For 1984-'18 HD® Big Twin Engines, 1986-'19 HD® Sportster® Models, And 1994-'02 Buell:
Fits 1984-'18 HD® big twin engines, 1986-'19 HD® Sportster® models, and 1994-'02 Buell®. Our forged steel roller rocker arms were designed for superior strength and to eliminate the failure-prone stress areas found in some other rockers. S&S® roller rockers are forged from 8620 steel, heat-treated, and then shot-peened for additional strength and protection from fatigue. Our rockers also utilize 3/4" long bronze bushings, compared to the more common 1/2" long bushings or needle bearings. The end result is what we believe to be the finest rocker arm available anywhere, for any price. Extremely durable rollers reduce valve stem side thrusting with high lift cams. Superior wear and fatigue resistance even in the most demanding.(2 front and 2 rear rocker arms)
  • Roller Rocker Arm Set For 1966-'84 HD® Big Twins:

1966-'84 big twins SH-Series engines. S&S® rocker arms for shovelhead engines are machined from 8620 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, with 50% more load bearing surface than stock .500" bushings. An oil passage from the pushrod cup of the rocker arm to the inside of the rocker arm body allows top-end oiling through the pushrods when used in conjunction with S&S® billet tappet guides and S&S® Quickee pushrods. Oiling can also be done through the stock 1966-'84 external oiling system. Nominal rocker ratio of 1.5:1. 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.
