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.
