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.

The ProX kit just replaces the OEM valves & valve springs and can be installed using the OEM retainers, bases and valve seals.Fitment
