The new latest spec clutch kit from UFC for your Losi 5ive, this bell accepts stock style pinions and fits both the 5T and new 2.0 version (shim correctly to suit either car).
This kit has been winning races across the world. Get the jump on your friends and youll be able to run an extra pinion tooth without loosing acceleration over standard 54mm clutches.
The Bell is designed with a recess on the inside so that you fit a socket cap retaining bolt through the inside of the bell and lock the pinion in place with a nyloc nut to prevent it coming loose.
