I have a 2" body lift and 34" Swamper LTB's on my '88 4Runner. The hardest part with lifting the body was lengthening the steering shaft to the steering box. The front hard lines for the brakes have to be moved around to make up for the lift. With 2" it didn't take much but with 3" you might have to unclip them from the body. The tires rubbed on the fenders and fender wells a bit so I just trimmed the fenders and hammered back the inner fender well.
