The slider shoes will need to be replaced on a regular basis to prevent premature governor cup wear so we have included 3 replacement slider shoes in our kits. This kit is all you should need to do the next 2 or 3 500 Mile services on your Can-Am X3 or Can-Am Defender clutches. Includes 3 Slider shoes, 3 governor cup damper rings, 2 thrust washers, and 1 tube of special bearing grease.
