Here we have a good used rear differential removed from a 2022 GMC Sierra 2500hd SINGLE REAR WHEEL with the 6.6 duramax. This has 3.42 gears with G80 limited slip differential option. Fully functioning condition with no issues or damage. Should fit most 19-24 GMC 2500/3500 single rear wheel trucks only, but please confirm fitment BEFORE buying!
