It really depends on what you want, are you willing to move the spring hangers. If you just want an easy lift to stuff 35's or 37's then go with someone like All-Pro. 35's would be the biggest you could fit without having to either put a bodylift on or modify the wheelwells. Even 35's will require some minor mods if you don't do a bodylift. I think All-Pro has a set of springs that will move the centering pin forward enough so that you have enough clearance for 35's and they don't require moving the hangers. I'd contact them to see what they currently have.
