PRW Pro Series Stainless Steel Rocker Arms incorporate an exceptional design that provides plenty of clearance for large diameter springs. These stud mount rocker arms are manufactured from premium quality 17-4ph stainless steel, a superior alloy that is high in Nickel and Chromium. This rigid premium material provides high yield strength to help resist deflection and has extraordinary fatigue resistance. PRW stainless steel rocker arms feature full cage friction reducing needle bearings and extra large trunions to spread out the load and reduce wear. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to resist the severity of racing and to minimize scrubbing.
