Belts for cleated tracks are no longer available from arctic cat. You will have to find a used belt on EBAY, at a salvage yard, or upgrade to a rubber track. An Arctic dealer can look up pieces needed to upgrade to rubber track from the old accessory parts listing to do the upgrade. You will need to replace your drive sprockets and possibly the drive axle to run a rubber track with out cleats.
