Is there a better choice in seconday clutches to go with, they all appear to have seperate part numbers (2008-2010), so i assume they are not the same, I see polaris made one for a rzr 800 non s (2008), rzr 800-S (2009), and changed the S model again in 2010-12. I have been told the 2009-S is the best secondary to go with. I'm looking for any advice on this. I have a 2008 standard clutch i was gonna try using in my 2009 S just to see how it works out. anything i can hurt by doing this?
