A open differential sends all available torque to whichever rear wheel has the least grip, which is exactly the wheel that spins first on a wet road, a dirt trail, or a hard launch. The Detroit Truetrac replaces the open differential with a helical-gear limited-slip design that biases torque to the wheel with traction automatically, with no clutches or cones to wear out and no on-off engagement feel in daily driving.
