A trailer hitch particularly for pick-up trucks and other relatively light towing vehicles having an improved hitch assembly including a retractable pin assembly in combination with guide members for limiting angular movement of a trailer behind the towing vehicle. An improved cylinder, pin and restrictor plate assembly provides a rebound or kick back to return or urge the jack-knifed trailer back to a position substantially trailing behind the truck. The cylinder improved in providing positive action in both retraction and extension of the pin.
