About Rear Differential

Benefits of a limited-slip differential

The main advantage of a limited-slip differential is demonstrated by considering the case of a standard (or "open") differential in off-roading situations where one wheel has no contact with the ground. In such a case (with a standard differential), the non-contacting wheel will receive 100% of the power, while the contacting wheel will remain stationary. The torque transmitted will be equal at both wheels, and therefore, will not exceed the threshold of torque needed to move the wheel with traction. In this situation, a limited-slip differential prevents 100% of the power from being allocated to one wheel, and thereby keeping both wheels in powered rotation.
