An improved trailer hitch assembly of the draw bar type consisting of a receiver tube mounted on the tow vehicle to receive a draw bar tube in vibration damped retention while extending a hitch ball. The draw bar tube retains a resilient spring block assembly that is secured to the receiver tube by means of a hitch pin and the hitch pin moves within elongated slots on said draw bar tube so that vibration from the draw bar tube is damped by the spring block assembly and isolated from the receiver tube and tow vehicle. A shock absorber is connected between the receiver tube and some point on said draw bar tube.
