Abstract
A Trailer hitch for towing a four wheeled vehicle. The hitch has a fixed in place portion attached to the towing vehicle and a translatable portion attached to the vehicle being towed. The translatable portion is spring biased to a center position. A damper is attached between the fixed portion and the translatable portion to prevent abrupt movement of the translatable portion. The hitch provides controlled lateral movement between the towing vehicle and the towed vehicle to diminish wear on the front end parts and tires of the towed vehicle.
