you can run 30" on it with no lift and some minor rubbing...at $300 you probably won't mind pounding in the fenders and trimming them. Trimming the fenrders a little, 2" body and 2" susp should fit 31's with no problems.
Throw some 30's on it, trim the fenders a little and weld the rear.....then you'll go almost anywhere. Don't forget that the front pot is a weak link and there are a few fixes on the web. Strap it down to it doens't rotate.
