Looks like the rear suspension has the same rail ends the old ones have. Small enough to fit through the 3" windows on the track!
It seems so easy to build a 3.5" rounded (not pointy) knob for the rail end and fix a old problem that has caused many people grief in the past not to mention having the rear bumper crack my helmet as it endowed over me. If the sled landed 3" back it would have landed on my neck and I might not be worried about the "new Proclimb issues".
Just have to add 90 bucks to the price when you are looking at one.
