I went from the stock BFG ATs to 37x12.50x17 BFG MTs. I installed the Truxx keys and gave it a crank to level the truck out...very, very little rubbing for the first few thousand miles at full turn...but the torsion bar crank made it ride like sh!t.

Two weeks later I went with the Cognito leveling kit, upper control arms, longer Billstein shocks, etc...this brought the ride back to normal. Good luck.
