New OEM XMR Rear Differential Gear Kit, 10/36 Ring & Pinion Gear Set, Timken, Dichtomatik or SKF Seals, NTN or IKO Pilot Bearing, OEM Gasket Kit and OEM Bearings. Fits the larger style (80mm pinion seal) 800/850/1000/1000R XMR REAR differential first introduced on the 2013 Outlander 1000 XMR. This kit will upgrade your 2019+ ATV if you have an 80mm pinion seal to spiral bevel gears. In our opinion, they are superior due to the increased contact area between the pinion and ring gear. This gear kit will not fit in 2013-2018 650 XMR and 570 XMR differential cases (with 70mm gear seals). Please see our other listings. This is a common replacement part on 2nd generation ATVs. We sell complete kits for this, please see our other listings. Part # 703500870
