4th Wheel Kit...
These kits are suggested for cross-country racing and/or trail conversion applications.
With the Speedwerx 4th wheel kit installed, you will have a more stable ride under acceleration. This kit prevents the sled from "walking" when the skis are off of the ground.
Kit comes complete with lightweight aluminum spacers, idler wheels, all necessary mounting hardware and full installation instructions.
