Description
If you're pushing your engine to its limits, OEM valves and springs will hold you back. The PROX 28.SIS6351-2 Kit replaces factory components with nitrided steel valves and premium chrome vanadium springs engineered to withstand extreme RPM and boost conditions without fatigue or failure. This is a direct upgrade for serious builders and racers who demand reliability under sustained high-performance demands.
The nitrided steel valves resist wear and thermal stress far better than stock, while the specially calibrated valve springs manage the extra inertia of heavier steel valves and deliver consistent lift at high RPM. Installation is straightforward—the kit uses your existing retainers, bases, and seals, making this a bolt-on upgrade without custom fabrication.
