Go Kart Clutch | Available to Buy Online

The most commonly used Go Kart Clutch is the centrifugal clutch. These items join two shafts together to help keep an internal combustion engine running when the output shaft of the engine is suddenly stopped, or when the output shaft is slowed down considerably.

It accomplishes this task by disengaging the loads whenever the engine is just starting up after being stopped, and when the engine is idling. The clutch keeps the engine running, and it allows the vehicle that it is placed on to have increased speed, increased power, and a faster response time for speed pick up, and for slowing down.
