It's just gonna look 3" taller... and like it needs bigger tires. What are you trying to gain out of the body lift? Are the tires rubbing as is?
Personally I wouldn't do a body lift unless you need more tire clearance and don't want to cut the bumper and fender... you're just going to expose more frame and there will be a 3" gap between the hitch receiver and the bumper. Your running boards will hide most of the frame though.
If more tire clearance is what you're looking for, I have a real trick way to trim the front bumper edge and back of the front fender so that it is almost un-noticeable. I have 305/70/16's on my K2500 and no lift this way.
Mya I’ve chose not to go this route...
