Speedmaster Aluminum Rocker Arms are used around the world by professional racers, engine builders and hot rod enthusiasts, offering outstanding power and performance advantages for street, strip, and track applications. Made from high strength 6061-T6 aluminum extrusions, each piece is precision CNC machined and finished by hand to ensure that out customers receive the very best Speedmaster has to offer. Speedmaster shaft mount aluminum rockers are specially machined to allow for larger springs and retainers with full-cage friction reducing bearings for added durability. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to minimize wear that naturally occurs between the roller tip and the valve stem. Not compatible with factory heads. Aftermarket heads only.
