you actually have to buy the powerband from your local dealer, once you get it home stretch it out real good and pop your wife or gf on the rear end with it, not too hard tho....
Then you need to lubricate the powerband with a solution called "astroglide", not too much tho...youll get slippage and slippage leads to the exact reason you needed a powerband in the first place....
Contrary to popular belief the powerband must be kept in its original packaging until installed. Its a powerband and it will try to attack other powerbands if they get to close to each other. You dont want the Powerband Welfare services coming to your house and taking your powerband away.......
