I think its kind of hard to find a good set cause of where the mount.. From the factory there really isn't any good places to just bolt a set on. The rear brace can just bolt to the frame.. But the front and middle is a little different. Most all the premade ones just bolt in where the lower plastics are. Its only a piece of 1" tubing..
I added a gusset to the front of my RZR. Then I welded a bung directly to the plate for my kicker to attacth to. My middle support comes off the middle cage piller a little like joe did his. Then the back just bolts in to the upper frame..
I'm not sure if you can even find a premade set that will just bolt on that are good and solid. You might end up having to do like joe and add some braces. But before I spent 4-500 bucks on a set and then had to beef them up. You might want to check around for a local fab or welding shop and see if they could help you out.
