[edit]

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 control. The rear axle is based on theDana 60axle.
