Nothing wrong with having both a suspension lift and a body lift. I have a 4" suspension lift and a 2" body lift on my CJ7.

BTW, if you have a 2" suspension lift with a 2" body lift, you will have a LOWER center of gravity than you would if you had 4" of suspension lift. That's because the last 2" of lift (the body lift) is NOT lifting the frame, engine, and drivetrain, but just the body in order to run bigger tires.

Some potential areas to pay attention to when installing a body lift:

(1) Make sure electrical wiring isn'g getting stretched too tight. I didn't have any problems here, but you should check anyway.

(2) Check the clearance between your radiator fan and the fan shroud. This only applies is you have an engine-driven fan, not an electrical fan. I had to cut away a little bit of the bottom of the fan shroud.

(3) Check your clutch linkage and your tranny shift linkage. I have an auto tranny, so didn't have to worry about the clutch, and I have a B&M cable-operated ratchet shifter, so I didn't have to worry about tranny linkages.

(4) Check the floorboard clearances for any tranny or t-case shifters that come up through the floorboard. Some folks have to enlarge the hole in the floorboard a little.
