This will only work with a 4" lift, IMHO. A 4.5" bs will be too much for the 2" spacer lift, it'll rub like crazy at the pinch weld area. I was looking at 4.5"bs wheels before I purchased mine and realized it was a bad idea without the proper lift and fenders. I'm not saying it will not look good, just not very functional for offroad. Like I said, this is just my opinion.
