Quiet Hitch stops sway and wander before it begins by eliminating any free play between the receiver and the tow bar (or bike rack, ball mount or whatever you insert) for a solid, seamless connection. Consistent pressure keeps your towing combination tracking straight through curves, cross-winds and sudden maneuvers — all with considerably less effort on your part. Especially effective on towing combinations with multiple hitch extensions; also reduces free play and noisy rattle caused by bike racks or hitch accessories.
