ABSTRACT:
A hitch assembly is provided having a hitch shank configured to be received within an opening of a hitch receiver of a tow vehicle and a wedge member disposed about the hitch shank. The wedge member has first and second surfaces on opposing sides of the wedge member, angled relative to one another. An engagement device is coupled to the wedge member to press the wedge member to an engaged position that causes the hitch shank to bias away from the receiver tube to minimize play therebetween.
