I think these will fit ski doo and arctic cat, but double check to be sure before buying. They have 9 teeth, 2.52 pitch, and 1 inch to 1 and 1/16th inch shaft. I bought them for my polaris, but am putting a different track on that requires 3.0 pitch and 7 tooth. They are used, but in excellent condition. I will ship them to the lower 48 for $80. New they are about $160. Please pm me if you have any questions. Thanks.
