* At this time these boards will not work on the 2020/21 X. We are working on providing a solution to the limiter strap adjuster and tunnel differences. 

 The new Ski Doo Gen 4 850 Skinny Running Boards are here! The Gen4 has proven to be an amazing machine. We have designed the ultimate set of running boards to give you excellent snow evacuation and superior rigidity. This also allows a more positive feedback from the machine when maneuvering. We have narrowed the boards 1" and raised the outer rail 3/4" allowing you to pull the plastics in closer to the body. 

This set of boards come with additional brackets for front mounting, block off plates for the plastic modification, and a custom drill bit that is required to finish the installation.
