You really need 4 inches of lift to run 33 inch tires if you do any real off road driving. I have 4 inches of lift in front and they do not rub at all when disconnected. I have 3.25 inches in the back and they will rub on occasion in some really flexy situations. If you go with the 4 inches of suspension lift and a 1 inch body lift you should be okay to run 35's. You will however need to consider drive line mods, regearing and axles along with some others in order to properly run 35 inch tires.
