Here are some specs as it sits now: 22re, r151f, dual 2.28 cases, 5.29 yukons, detroit rear, open front, km2 35's. I have an aussie locker on the way for the front. I recently got some 2x2 and fabbed up a tire carrier. It turned out to be not as heavy as I thought it would be. It's the tire that has all the weight in that deal. Also fits a highlift, not in the pics.
