This new clutch is machined at a different angle than stock which lowers your gearing and helps you climb hills. Also has a firmer spring which keeps the disks closed longer. Comes with heavy duty belt. Fits all EZGO 4 stroke motors. Installs in less than 3 minutes. A great upgrade, you will be surprised how much better your lifted cart go up hills. It's like dropping it into a lower gear up hills.
