Make sure you keep an eye on the clutch line as you lift the body off the frame, it may need to be extended. I was able to just bend the bracked down a bit and haven't had any problems. You'll also need to remove the lower fan shroud or move the radiator down 2". I just removed the shroud and it's cooling fine. You will also probably want to loosen the steering shaft slip joint. Obviously you'll need new bumper brackets to raise the bumpers 2" and poly body mount bushings would also be a good idea (4crawler or JCWhitney).
