Prox Exhaust Valve Conversion Set Ti-steel Yam

Latest addition to the prox program is the exhaust valve & spring kits. this kit is offered as an alternative where the oem application uses titanium valves. prox has now developed the exhaust valve & spring kits, containing a set of steel intake or exhaust valves plus a set of specially designed stronger valve springs. the prox kit just replaces the oem valves & valve springs and can be installed using the oem retainers, bases and valve seals.

• Springs are made from premium Chrome Vanadium Steel for higher performance and durability at high RPMs
• Nitrided valves offer high microhardness while supersmooth surface finish reduces friction between stem and guide
• Fully rebuildable with OEM retainers, bases and seals without the need of any further engine modifications
• Comes as complete package for quick, easy and cost efficient replacement
• Steel Valves for increased durability and less wear under extreme conditions
• Special stronger valve springs deal with the extra weight of the steel valves
