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) with reducing friction.

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