BluMax aluminum roller rockers are built of the finest 6061 aluminum extrusions which gives you superior strength over other rockers. Rockers are specially machined to allow for larger 1.55" springs and retainers with full-cage friction reducing needle bearings for added durability. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to minimize the wear that naturally occurs between the roller tip and the valve stem. Includes polylocks.
