This is a go kart clutch that fits a 3/4" shaft and uses a #41 size chain (chain not included).

The sprocket on the clutch is a 13 tooth. This is a larger sprocket than most karts come with so it will increase your top end speed if you have a smaller sprocket currently.

For example if you have a 10 tooth sprocket now and your top speed is 40mph this 13 tooth sprocket would give you a 10 mph top speed gain! You will lose bottom end power and gain top speed.
