Moose Exhaust Valve Kit

  • Each kit includes stainless steel valves, high-rev valve springs, lightweight retainers, and Viton valve seals
  • Stainless steel valves are made from a one-piece forging featuring 21-4N material
  • Valves are heat treated and feature a nitride process on the surface, which improves valve wear and overall performance
  • High-Rev Springs are coiled with a proprietary high-quality wire that undergoes a heat treating and stress-relieving process, which dramatically increases the spring's life-cycle and improves valve stability at high RPMs
  • Valve seals are made with Viton rubber which allows for greater seal and less stiction
  • Made in the USA
