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.  
Fits 2016-Up RZR models with the square roller 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 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. Install new rollers on new roller pin, then re-insert the small roll pins back into the clutch after aligning the roll pin.
