Info

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
  • Set of 16
