I still have a stock clutch sheave from my Wolverine Rspec after I replaced it. My question is does anyone think or know if that sheave would work on my Grizzly? Also I still have the secondary spring and weights and wondered if that would be useable for anything as well? Totally random question but I'm cleaning out the garage and bored today lol! Any reply is appreciated!

Doesn't the R spec 708 have a fan on the secondary? I don't believe there is any other difference.
I see the new R spec 4 seater have a redesigned CVT.

There's not any quick cross-reference I could figure out quick, but looking at the OEM r-spec sheave, it's the same OEM sheave as the Viking. r-spec is the 708, and the Viking is the 686. And we know your 550 interchanges sheaves with the 686. So that's enough interchangeability for me to give it the old college try! Count your before and after pulley ratios, take your time, and report back. Could benefit others.
