I have a 2008 polaris dragon switchback 700. I extended it to 144" and put an 1.75" Challenger track on it. I really like the sled, but do not like the coupled rear suspension. I do alot of off trail riding and I took it to the mountains last winter and it was not good. I am planning on heading to the mountains again this winter and I would like to keep the sled one more year. Can I get some suggestions on what I can do to get the sled to handle better in powder. What are some options?? RMK suspension?? aftermarket suspension?? Uncouple suspension if possible?? Most cost effective?? Different Sled?? If I would get an aftermarket suspension, would it fit an 1010 polaris RMK?? Any input would be appreciated.
