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.
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

Springs are made from premium Chrome Vanadium Steel for higher performance and durability at high RPMs
Fully rebuild able with OEM retainers, bases and seals without the need of any further engine modifications
