Ski-Doo quit installing a washer on the ski bolt some time ago.  We send 2 fender washers with every set of EZ WheelZ just for this.  Although they will work without them, over time you may see the axle will indent into the plastic ski and reduce  the amount of  ground clearance.  We recommend you install these washers behind your nut before using the wheels on your sled.
