    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.

    • 4340 steel rocker body
    • Adds up to 30 HP over stock rockers
    • Excellent replacement for stock or sportsman engines
    • Eliminates noise & slop associated with worn or high mileage rockers
    • Includes polylocks and grooved balls
