A 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. These are also a higher quality replacement for the inner rollers. Requires removing helix so we recommend upgrading these if you're installing a Stage 2 clutch kit. Just order two sets for a complete rebuild. Fits 2016-Up RZR models with the square slider BOSS secondary clutch (See picture 2 for reference) Better wear resistance Smoother clutch shift Faster clutch shift A must-have addition when purchasing one of our S2 clutch kits for your 2016-23 RZR XP 1000, RZR 1000 S, General, or RZR 900 S, Trail, XC Replace simply by using a punch to pound out roll pins & roller pin.
