Description
Stock valve springs lose their tension under sustained high-RPM operation, causing valve float and compromised combustion timing—exactly when you need precision the most. The PROX 28.SIS6329-2 pairs nitrided steel valves with premium chrome vanadium springs to eliminate that weakness, delivering consistent lift and sealing even under extreme conditions. If you're pushing your engine to its limits, OEM valves simply won't keep pace.
This kit installs using your existing retainers, bases, and seals, making it a straightforward upgrade without requiring machine work or custom fabrication.
