Valves and Valvesprings

SKU: MWR-300607 Category: Brand:


This titanium retainer set replaces your stock steel retainers, greatly reducing valvetrain mass and allowing higher engine speeds (higher RPM) without valve float. A must for any engine that will see extreme high RPM use such as drag racing or sustained high RPM use such as road course racing. Direct replacement, no modifications necessary. Add upgraded valve springs for even better protection from valve float!
