Re: 83 suburban 1/2ton to 1ton conversion help

Make sure you get the Full Floating 14 bolt, not the semi floating. I'd swap in Hydroboost while you're doing this. These axles will not bolt in. You will need to cut the spring perches off the axle and weld new ones on. Your frame is wider than the frame on a 1 ton. This also gives you the opportunity to adjust pinion angle some if you're going to lift it. It's not totally bolt-in, but not as hard as some other things to do to one of these old squares.
