"This is the XMR 1000 rear differential found in 2013-2018 800R 850 1000/1000R XMR.\r\n\r\nIt will fit g2 bikes (500/650/800/850/1000) if you are upgrading you will need to shorten your shaft 1.75\" or buy a kit from us, please see our other listings.\r\n\r\nThis differential has automotive style cut gears, tapered roller bearings, along with an overall larger gear size. There are a total of three bearings on the pinion gear giving it much more support over the standard rear differentials, this requires a shorter driveshaft, as mentioned earlier if you are swapping this in place of a standard differential.\r\n\r\nPinion spline count 20, standard differentials use 18 spline pinion shafts, that are smaller in diameter.\r\n\r\nIn every way this is a beefier differential.\r\n\r\nTo bolt your driveshaft on this differential you will need a M10x1.25 16mm long bolt (not included)\r\n\r\nCurrent part number 705502546\r\nOld part number 705502178,  705502090"
