The system was primarily used on pickup trucks. At lower speeds, it turns in opposite direction of the forward wheels to a maximum of 15°, or 12° in trailer mode, decreasing the turning radius as much as 21%. At higher speeds the system will turn the rear wheels slightly in the direction of the front wheels so as to increase stability and ...

The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
