Intake Valve Conversion Set Ti Steel Yam

Latest addition to the ProX program is the Steel Intake and Exhaust Valve & Spring Kits. This kit is offered as an alternative where the OEM application uses Titanium valves. ProX has now developed the Steel Intake and 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.
Features:

• Steel Valves for increased durability and less wear under extreme conditions


• Nitrided valves offer high microhardness while supersmooth surface finish reduces friction between stem and guide


• Special stronger 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


• Springs are made from premium chrome vanadium steel for higher performance and durability at high rpms


• Comes as complete package for quick, easy and cost efficient replacement
