Not sure what would give you this impression. I can assure you that the opposite is definitely the case. You gain nearly a foot out by the tires. In the center, the skid bolts to the crossmember, so at worst, you aren't loosing anything there, but I'm pretty sure the stock skid/splash guard thing hangs down lower.

This one has a spacer lift, but just look at all that clearance. Look back at the very first pic in this thread. See all that black plastic by the tires. That is where the stock bumper sits.
