The tracks were used on a 2019 Polaris XP1000 crew cab side by side. They may fit other years/models of Polaris vehicles. They were mounted for four seasons. I used them to go from a plowed road on an unplowed road to our mountain cabin about a mile away. They have never been used off road and only have been driven by a man in his 70s. I am selling them because we no longer travel to our cabin in the winter. This tracks new cost $6600 plus tax and shipping. I will only communicate by email. I will NOT call you. If this ad is up I still have the tracks.
