I think they have a kit or something that allows the use of PPS on that skid.....maybe somebody else knows..... I believe you have the RydeFX as original equipment, so i would get Fox because they're rebuildable, but it depends on your ryding style. My buddy bought a pair of the Gold colored Fox shocks at Haydays for $60 a piece new for that exact same Polaris you have. Shop around for prices.
