New out on aliexpress, full alloy HD differential units, these look superb, ring gear and spider housing is all one piece with bolt on end caps

under hard abuse the plastic diff housing can stretch and the spider gears can slip damaging the teeth

just need banggood to get stock and a sharper pricing and happiness filled!
