Very good condition. Carved out of solid billet, this chaincase drops and rolls your driveshaft on the 2011 - up PRO RMK's. (not for use on belt drive models). This allows for increased clearance in front of your driveshaft for the wet heavy snow conditions, or to run a 3.0" paddle track with 8 tooth drivers. Maintain the stock balance of your PRO RMK. This kit does not require you to remount your rear suspension. Comes with chain. $500.00 plus shipping.
