The rear axle of a kart is incredibly important. It’s not only the driving axle, but it’s also the axle that determines how much grip your kart has when cornering. The rear axle is responsible for translating the power from the engine onto the tarmac.
Finding the right setup for your rear axle is not easy though. You need your rear axle to work properly based on your driving style, but you also need to ensure that the kart’s chassis works as it should.
