This new belt drive is the latest thing to hit the snow, we have spent all summer long testing this clutch and found it to be a very good set up especially for (ISR) champ class racing. It has many tuning components available. For a serious racer, this is the only thing to have. JR BELT DRIVE KIT includes 1 primary clutch with weights and spring, 1 secondary clutch, 1 drive belt, and 1 clutch bolt.
