Hawaya Racing has re-designed their lock-up retainer commonly used on the Pro Fuel slipper clutch hats. The earlier units were prone to wear after a period of use. HRP has re-designed this unit to include carbide disc recessed into the retainer in the area where the lock up fingers contact it. This will eliminate any wear and allow for smooth action of the retainer through out the life of the slipper hat. We have just completed a run of these and have them in stock ready for immediate delivery.
