If your class or budget does not allow aluminum or stainless roller rocker arms, check out these steel roller tip rockers. Made from 4340 heat treated chromoly steel, they feature a longer slot to eliminate stud bind issues. Plus, the roller tip minimizes scrubbing (the result of the valve stem pushing hard against the valve guide), reducing friction and freeing up an additional 15 to 30 horsepower over stock rockers.
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.
