It adjusts the breaking between the front and rear when there is a load in the bed.
Some remove it all together, others cut off the bar at the end of the axle and make just a stub left at the valve and leave it adjustable, and others leave it and make a braket to raise the axle end when lifting their rigs.
It's up to you and wether or not you expect to carry any loads, for wheeling it's not really necessary.
Mine's cut off and is adjustable by an I bolt and bracket to frame, set at the stock level.
