Specifications:

  • This ProX kit includes steel valves for increased durability and less wear under extreme conditions.
  • Nitrided valves offer high microhardness while a super smooth finish reduces friction between stem and guide.
  • The valves are accompanied by stronger valve springs that deal with the extra weight of the steel valves.
  • Springs are made from premium Chrome Vanadium Steel for high performance and durability under high RPM.
  • Fully compatible with OEM retainers, bases and seals without the need of any further engine modifications.
  • Comes as a complete package for quick, easy and cost effective solution.
