A hitch tightening pin system is designed to attach a draw bar to a hitch receiver tube and prevent relative motion between the draw bar and receiver tube. The pin system has an elongate tapered shoulder bolt that has a larger and smaller outer diameter with a tapered surface extending between the larger and smaller outer diameter. The system includes an expansion sleeve that has arcuate portions. The expansion sleeve can slide onto the smaller outer diameter with the arcuate portions facing the tapered surface. A nut tightens to move the arcuate portions radially outwardly to apply force to the inside surface of a draw bar. The application of force causes the draw bar to be held tightly to the receiver tube and reduce or eliminate looseness or rattling during use.
