ProX Steel Valve and Spring Kits are 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 developed Steel Valve and Spring Kits that contain a set of steel valves plus a set of specially designed stronger valve springs. The ProX kit replaces the OEM valves and 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 a heavier valve spring must be used!

Answer QuestionProX valve & spring kits are sold as a set to service either; the exhaust or intake valves on any machine you select from our fit guide. Once you choose your exact model, you'll be presented with the option of choosing the intake or exhaust positions, assuming both are available for your ride. You might as well do both, however, since you're already in the top end!
