dont waste your money on the assault !!! I've got a 2012 and yes the shocks work great but no, in stock trim even with the powder track it will not climb and sidehill with the pro.
My assault now has the skid in the pro rmk position, I have pro rmk ice age rails and a camo ex track (ripped the 5.1), ski's at narrowest setting and played with springs/shocks lots.
keep in mind I'm not say the assault isnt a good sled, I love the way the sled works now just think for the price difference I would have been better off to just buy the cheaper pro and get shocks for it.
so my plan next time is buy a pro and put exit shocks on it.
