No track bar on the TTB, its just angle sensitive. Thankfully the desert guys have really done a good job in figuring out how to make it work well. After throwing on a basic lift I understand how twin traction beam gets a bad wrap.
No, It drives just like it did on 31's. I don't need big tires like I had on the blazer and suburban. If it gets an ls swap I might go to a 315 size tire.
