Description

Our Assault Racing Sportsman Series steel stud mount roller tip rocker arms are the ideal choice for a large cross section of engines; whether it is a mild street rebuild or the performance requirements of off-road, circle track, drag racing, or marine applications. The 4340 chromoly steel rocker bodies feature a longer pivot slot for higher lift camshafts and are much stronger than die-cast aluminum or stamped steel, minimizing rocker arm flex. The roller tip minimizes scrubbing (the result of the valve stem pushing hard against the valve guide), reducing friction and freeing up additional horsepower over stock rockers.
