Just got my rear shock on. It wasn't to hard after we found out what size washers we needed. I haven't been able to test it to much yet, because I can't go off of jumps (snow) But from what I can tell by just riding around is that it soaks up bumps a LOT better, and the whole quad is more stable. It lowers the ride hieght by about 2 inches on the softest preload setting. If you guys have any questions on installation just ask here.
Close up of the bottom mount. I had to put a couple small washers on each side, same with the top. I also had to drill the shock mounts slightly larger. I went from a 10 mm bolt to a 12 mm bolt. Thats about all the changes I had to make.
I might do the front, still haven't decided. People that did do the front shocks said that you should get wheelspacers to go along with it, I don't know if I want to put that much money into it. But I definatly reccomend doing the back!
