The larger diameter combined with the higher quality alloy of these bars stiffen the suspension so your tires stay in contact with the ground better in the rough stuff. You do NOT want to crank your TB's to the max because you lose suspension travel when you do this. You'll be on the bump stops all the time off road. I have mined cranked somewhere between 1 - 2" and get the rest of the clearance I need with a 2" body lift and fender well mods.
