Prox Dirt Bike Steel Intake Valves and Spring Kits
• An alternative where the O.E.M. application uses expensive and less durable titanium valves
• These steel valves offer increased durability and easily extends the lifespan to 3x that of the O.E.M. titanium valves
• Nitrided valves offer high micro-hardness while a super-smooth surface finish reduces friction between stem and guide
• Special stronger valve springs deal with the extra weight of the steel valves
• Springs are made from premium chrome vanadium steel for higher performance and durability under high RPM
• Fully rebuildable with O.E.M. retainers, bases and seals without the need of any further engine modifications
• Intake and exhaust kits complete packages for quick, easy and cost efficient replacement
