I paid a grand to have my Pro shocks revalved and the remote reservoirs put on. The front shocks worked pretty good. Liked to be able to stiffen them up for a bumpy trail ride out or to get the sled to carve better in deep, heavy snow. But the rear suspension is just awful. Set up like the manual says(and I tried a lot of set up that didn't work any better) the rear sags almost halfway thru it's travel. Then it get's to a point where it almost locks up. I think a double or better yet a triple rate spring would help that but then I would have been $1300 into OK shocks. Another $700 for Tom's Foxes or Raptors and you are in heaven. The Assault comes with those shocks stock but if you want what the Assault is advertised to do you are much better off with better shocks. If you ride pow every day, no trail at all, you won't notice any problem. Soft snow doesn't test a suspension.
