Just the difference in suspension!!!

I know about all the other differences.

I understand that the A-arms and trailing are high clearance. I know that the rear reservoir is not remote. What I’m asking is about is 1: the valving different ?
2 : are the spring rates different?
3: anything else I need to know?

I had a 14 rzr with a racerteck spring kit, and now need a new rzr . ( totaled it)
I have ridden in a highlifter and the was night and day different ride.
I need some input before I get a highlifter. ( love the low gears ) I know kings or fox or etc etc blot on is a great way to go, just need other economical options Just looking for a better ride on the trails.
