Description
If you’re running your engine hard at high RPM, stock valve springs simply don’t have the strength to keep up—resulting in valve float, lost power, and potential catastrophic failure. The PROX Valve and Spring Kit 28.SES3338-1 replaces those weak OEM components with nitrided steel valves and premium chrome vanadium springs engineered to handle extreme conditions without compromise. Drop this kit in during your next valve service and gain the reliability and performance stability that separates serious racers from the rest.
