Description
Stock rocker arms limit your engine’s potential, introducing flex and wear under high RPM stress. S&S Cycle’s roller rocker arms deliver superior load distribution and durability through a .750″ bushing design—50% larger than stock—engineered to handle forced induction and aggressive cam profiles. Built from 4140 forged steel and heat-treated for maximum strength, these arms maintain precise valve timing and reduce parasitic losses across the entire rev range.
The 1.5:1 rocker ratio is optimized for Shovelhead engines, and the pushrod oiling design simplifies maintenance when paired with S&S tappet guides. Whether you’re running a stock or billet rocker box, these U.S.-made arms are a straightforward bolt-on upgrade that transforms reliability and performance.
