You need a passenger drop transfer case. You need to remake all of your exhaust. Driveshafts will have to be modified. You dont want the springs they are too long and would make your jeep a skyscraper. Plus they would need you to relocate front and rear mounts. You will have to do spring over if you have not already. You will need a new steering setup either inverted t for 200 or crossover for more. Brakelines. You need 8 lug wheels.
Unless you know what you are doing and can fabricate its not a good idea.
