Trailer hitch apparatus including dampening mechanisms to simultaneously dampen vibration and shock in a longitudinal direction and vertical direction. T he apparatus consists of a hollow draw bar tube capable of being removably coupled to a vehic le mounted receiving tube. The draw bar tube is adapted to move longitudinally relative to the receiving tube while a biasing means within the draw bar tube provide dampening of shock a nd vibration in the longitudinal movement. The apparatus further has a ball hitch a ssembly carried by a transverse support bar attached to an outer portion of the draw bar tube. The ball hitch assembly is biased against vertical movement thereby dampening shock and v ibration in the vertical direction.
