The Blue Ox Tow Bar 3" Drop Receiver allows you to raise or lower your receiver hitch connection in order to accommodate a tow bar. This Drop Receiver is rated a Class IV for 10,000 lbs of towing strength with a 3" rise/drop and a 12" stinger length. Best of all, the Blue Ox Tow Bar Drop Receiver is easy to install - just insert it like you would a ball mount. However, do keep in mind that it is meant for tow bar use only. So if you need to flat-tow a vehicle but don't have the proper receiver height for a tow bar, use a Blue Ox Tow Bar Drop Receiver and equip your tow bar with extra versatility.
