Description
If you’re running your engine at sustained high RPM or pushing it beyond stock parameters, OEM valve springs will eventually lose their snap—and valve float becomes a real problem. The PROX Valve and Spring Kit 28.SES2444-1 pairs durable nitrided steel valves with premium chrome vanadium springs engineered to handle the extra load without compromise. This is a direct replacement that uses your existing retainers and seals, giving you track-ready reliability without a complete top-end rebuild.
