Well.. Kinda tuff to say. Having lifted a few Jeeps, 3" sure shouldn't cause any problems. The sway bar end links shouldn't care about the new position as long as nothing is rubbing. I think I'd put it on jack stands (under the axle) and steer it lock to lock to see if anything looks not right and nothing is rubbing.
