The hubs don't seem to fit my particular application even though my quad was listed in their description. 2006 Polar Hawk's Eye 2006 2×4. I had to cut one of the bars in half to fit, as well as modifying my quad's mounting holes to allow the upper arm to accept the bushings. See fig. Had to spend extra money and time to make it work. I spent more time resizing the bars and mounts than I did changing bushings.
