To take care of unequal torque power distribution, the selectable (manual) and automatic locking rear differentials were developed. The wheels of a car fitted with a locking differential will have the same rotational speed as they are interlinked or locked in relative motion to each other. Regardless of the traction (friction) experienced by a wheel, the rotational speed is maintained and to be the same for both. Locking rear differential offers better traction for wheels compared to the open one.
