A body lift will give you clearance to fit larger tires, by lifting the body higher off the frame. I personally am not a fan of bodylifts, but it's a cheaper way to get bigger tires, and is fine if it's mainly for looks... even though IMO, body lifts make a truck look worse - you get big gaps between the bumpers and the body, and you see a lot more frame. But to each their own, I guess.
The only thing that gives you more ground clearance between the axles and the ground, are larger tires. Suspension lifts DON'T give extra ground clearance. When I installed my suspension lift, my axles were still at the same level as before, UNTIL I mounted larger tires... then I gained an inch of ground clearance (I went from 29" to 31" tires). [/b]
