Polaris Ranger 800 front differential cases, 2009-2012 fitment, can also be retrofitted to 2013-2016 Ranger 800 models. 3 available. These are very common to break and no longer available from Polaris, and were close to $700 before they were discontinued.
Clean differential case - $500. New pinion bushing.
Two other differential cases - $300 each. Need new pinion bushings installed, available in AllBalls rebuild kits.
