It's going to have to be pretty high to clear a 36" tire, sorry, even if you trim. You're looking at a 4" Superlift kit plus a 2" or 3" bodylift and 4.56 gears to make it run right, assuming it's a 4x4. If it's a 4x2 you could probably use dropped spindles and cranked t-bars instead of the full lift kit, still need the bodylift, at least shackles and maybe higher rear springs, and the gears. 10" rims with no more than 4.25" backspace, less than that is better, and you'll have to service the front wheel bearings a lot, at least once annually and maybe twice. Life of the tie rod ends will be short. Upgrade to braided stainless brake lines at least, bigger brakes would be a good idea with the dubs and IROK's because that's a lot of rolling mass. Basically there is lots of room in back, the problem is the front.
