1/8 diffs = set it and forget it! Stock gears with aluminum cups and cases work decent, but the 1/8 gears aren't much more $$ in the end, and you can tune with different weight oils, too. I still run the stockers in some trucks, and have even thought about modding some diff cups to accept diff oil, which should make them last a bit longer as well(lot less wear). For a truly thoughtless diff setup, 1/8 is really the only answer, though.
