I put this on my 2013 assault for the last 50miles last year. I dont have use for it anymore. It comes with 2 belts. Kit was $950 at CW last year when i bought it. Fits 2013-2015 pros and I am not sure if it will work on the nex AXYs or not. Gear ratio I believe is 2.42 I will double check..Asking $850.
