Exit X1 Shocks. Will fit Polaris Matryx or Axys chassis. I bought them new and put 930 miles on them. They are in perfect working order. They are valved for 200 pounds. The reason I am selling is I will be selling my sled at the end of the season and I do not think I will get too much more time to ride this season. New they are $1,250. Asking $850 plus shipping.
