Pro X Steel Intake Valve Conversion Set Yamaha YZ450F / WR450F / YFZ450 / YFZ450R / Gas Gas EC450F

The Steel Intake Valve & Spring Kits, developed by Pro X, provides a stronger alternative to OEM kits that typically use lightweight, yet less durable, Titanium valves. This kit introduces a set of steel intake valves and a set of stronger valve springs. The Pro X kit is compatible with OEM retainers, bases, and valve seals, and simply replaces the existing OEM valves and valve springs.

Features:

  • Steel Valves for increased durability and less wear under extreme conditions
  • Chrome vanadium steel valve springs deal with the extra weight of the steel valves
  • Fully rebuildable with OEM retainers, bases and seals without the need of any further engine modifications
  • Nitrided valves offer high microhardness while super-smooth surface finish reduces friction between stem and guide
