If you look at how it works.. when you raise the front, the stock track bar pulls the axle to one side slightly. It just causes things to be off center a bit. You get a longer/adjustable one to center the axle again. I run a 2" leveling kit on mine with everything else stock, and my dad ran a 3" or a while with everything stock. Now he got control arms and track bar because of the big offset wheels and 35s.
