Quiet the Valvetrain. Restore Lost Performance.

Worn, scored rocker arms rob the 4BT of valve lift, create ticking, and accelerate wear on pushrods and valve stems. These new heavy-duty rocker arms replace your tired originals with precision-machined, heat-treated components — no cores, no waiting, no guesswork.

  • New manufacture — no core charge or exchange required
  • Precision-machined contact surfaces for accurate valve actuation
  • Heat-treated for long service life under sustained load
  • Direct fit for 1983-1998 3.9L 4BT Cummins engines
