If I crank the bars up front and add-a-leaf in the back does anyone think that this would be a bad idea...im just going to be running 31x10.5 on 15x8inch rims...thanks

Depending on what wheels you're running, you shouldn't need to lift at all. I have 31x10.5's on 15x8's (3.75" backspacing I think, whatever it is for AR-767's) and they fit fine. If you do what you're thinking, you might be able to fit something a little bigger. ORR might be a good place to check since I know of a few guys over there running 285/75/16's (basically a 33x11.5 or so) and just cranking the torsion bars.

I dont off road often therefor I dont see the use for 33 inch tires but they would look cooler
