With a 6 speed, you should be good. I ran 35s with a 3" spring lift and a 1.25 BL. you have the 1" body lift, just buy the 3"springs and shocks, you are looking at $400. I ran 2" spacers out back and 3" springs up front (Level out the jeep with the winch up front). Oh ya, I my 35s were MTZs also, loved them, great tire.
