S&S Forged Roller Rocker Arms
S&S roller rocker arms are forged from 4140 steel, heat treated and shot-peened for additional strength and protection from long-term fatigue. These rocker arms ride on 3/4” wide bushings (stock is 1/2”), and feature a modified lubrication system for unrestricted roller oiling. Because the bushings are wider, we recommend new rocker shafts are used during installation if original shafts show wear in the bushing area. Available for Twin Cam® and EV engines in stock 1.62:1 or higher lift 1.725:1 ratio (modifications required), and Shovel engines in 1.5:1 ratio.
