2006 550 SuperSport rear shocks?

[JABIV]

I have a 2006 550 SuperSport that needs rear shocks that are not available through Polaris. What are you folks using? Part number and websites would be greatly appreciated.
Thanks everyone,
JB

From the parts diagram that looks like a rebuildable Fox shock in that sled, post a picture if you can.
