Do Fox or Elka shocks really make a noticeable difference on a 50 inch rzr

I have to ask, do Elka or fox shocks make a huge difference on a 50 inch wide machine or do you have to go to 60 inch wide to get a really noticeable difference? Also is the price diff between stage 4 and stage 5 elkas really worth it or would a normal person not be able to tell a bit of difference.

I do not race i mostly drove trails, woods, and the occasional swamp. Thinking about upgrading the stockers but its a large chunk of change and i don’t want to invest unless I’m going to be blown away by the difference.

Lets here what everyone with experience has to say.
