ROLLER CONVERSION KIT FOR SLIDER BOSS SECONDARY CLUTCH by Aftermarket AssassinsA MUST HAVE ITEM! These high quality rollers replace the square factory sliders found in all of the 2016 Up RZR clutches (Not RS1 or RZR Turbo). These actual rollers will improve shifting and will show less clutch wear. This is a great improvement and we'd recommend doing them as soon as possible to prevent your square rollers wearing too far into your clutch. Fits 2016 Up RZR models with the square roller clutch (See picture 2 for reference) Better
