PROX RACING PARTS
STEEL VALVE CONVERSION KIT
For the following models:
Honda CRF450R (2009 - 2016) INTAKE SIDE
Offered as an alternative to where the OEM application uses Titanium valves.
ProX has developed the Steel Valve and Spring Kits containing either a set of steel intake or steel exhaust valves, plus specially designed stronger valve springs.
The ProX kit just replaced the OEM valves and valve springs and can be installed using the OEM retainers, bases, and valve seals.
Features:
Steel Valves for increased durability and less wear
Nitrided valves for high microhardness while maintaining a super smooth surface finish reduced friction between stem and guide
Special stronger valve springs deal with the extra weight of the steel valves
Springs made from premium Chrome Vanadium Steel for higher performance and durability at high RPMs
Fully rebuildable with OEM retainers, bases, and seals.
