If your on a budget you might want to go with a RC 2.5, a 1 inch body lift, TJ flares, and mabe some trimming and you can fit 33s pretty good. If you dont like the body lift you can do like 5/8 boom shackles. With 4 inch you get into mabe needing an sye, and 34 tsl you would prob need to regear and step up the axles.
