        Pro X Steel Intake Valve Conversion Set Kawasaki KX250F
This kit is offered as an alternative where the OEM application uses lightweight, but less durable Titanium valves. Pro X has now developed the Steel Intake Valve & Spring Kits, containing a set of steel intake valves plus a set of specially designed stronger valve springs. The Pro X kit just replaces the OEM valves & valve springs and can be installed using the OEM retainers, bases and valve seals.
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
