On road centrifugal clutch technology meets off road racing with the Adjustable Clutch from Fioroni. This clutch features a four shoe design for maximum contact with the clutch bell. Adjustment is possible by simply tightening or loosening the spring nut and/or by replacing the shoes with either the teflon or carbon choices.

Spring adjustment is easy to change by rotating the nut at the end of the clutch. Tighten for higher rpm engagement, and loosen for lower rpm engagement. Regardless of track conditions, you have the ability to adjust the bottom end power of the clutch to allow the best performance for the given conditions. This will also reduce heat buildup and clutch wear.

The clutch comes with two teflon and two carbon shoes,  which offers the best balance of power and consistency. The teflon (white) shoes allow for more slip and are good for loose tracks. Carbon (black) shoes are generally better for high bite or tight tracks.

This clutch is perfect for off road buggies and trucks as well as rally/GT cars and even on road pan cars. Two versions  (39mm and 35mm) available to fit a variety of vehicles
