ProX Valve & Spring Kits
ProX Steel Intake and Exhaust Valve & Spring Kits. This is offered as an alternative where the OEM application uses Titanium Valves. Titanium is a very exotic material that requires a strict installing procedure to make it work well. The OEM Titanium valve quality in general is rather poor while high-end titanium valves are very expensive. Titanium valves need to be replaced at a regular base, resulting in many expensive rebuilds. 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 stonger valve springs. The ProX kit juts replaces the OEM valves & valve springs and can be installed using the OEM retainers, bases and valve seats. The steel valves offer increased durability and easily extends 3 times the lifespan of the OEM Titanium valves. Due to the extra weight of the steel the heavier valve spring must be used! Steel Valve & Spring Kit 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.
• Spring are made from premium Chrome Vanadium Steel for higher performance and durability under high RPM. • 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.
