If he cranks the T-Bars, don't crank them down as far as they will go. The ride will be pretty stiff. Also get the front end aligned. I'd say for what he's looking for a torsion bar crank would be fine. I did the same thing on my 98 ranger when I had a 3" BL and 33" Super swampers. Also just about all of my buddies with Z71s have cranked there Tbars a bit.
