This is a used 2013 Polaris Pro with less than 2,000 miles. Less than 50 on an SLP Stage 4 kit. I changed put in a new driveshaft at the same time. This sled has an Avid extended belt drive case with a C-3 belt drive. 8 tooth avid drivers with a 174X15 track. Raptor front shocks. This is a great running sled. Call for price.
