Steel valves offer increased durability and easily extends 3 times the lifespan of the O.E.M. titanium valves. Due to the extra weight of the steel, a heavier valve spring must be used. Pro X has developed the steel intake and exhaust valve and spring kits, containing a set of steel intake or exhaust valves plus a set of specially designed stronger valve springs. The Pro X kit just replaces the O.E.M. valves and valve springs and can be installed using the O.E.M. retainers, bases and valve sets.
- Steel valves for increased durability and less wear under extreme conditions
- Nitrided valves offer high microhardness while 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
- Comes as a compete package for quick, easy and cost efficient replacement
