S&S, 84-22 roller rocker arm set
With stock 1.625" ratio for a stock application replacement. Forged from 4110 steel, heat treated and shot peened for additional strength and protection from metal fatigue. In these rockerarms pressed-in, extra 0.750" wide, bushings are used instead of needle bearings. A 0.50" diameter aircraft grade steel roller tip ensures wear resistancy and maximum reliability. The lubrication system is modified for un-restricted roller oiling. For replacement parts see: 531870 Rocker arm. Front exhaust or rear intake. 531871 Rocker arm. Rear exhaust or front intake. 531368 Bushing .750". 531367 Complete rebuild kit which includes retaining rings (6), 531368 bushings (8), rollers (4) and shafts (4). Note: S&S advises the use of adjustable pushrods to obtain the required correct valve clearance. Note: Roller rockers are recommended by S&S with cams having more than 0.585" lift. Note: S&S does not recommend 1.745 ratio roller rocker arm sets for street bikes. These will increase stress on cams, tappets, and pushrods. For this reason they are recommended for racing only and not for street applications.
