2003-2009 Models, All FX Nytro & Phazer, All XTX, & Single Shot
03- 18 Japan built sleds have only 3 wheels on the rear axle This 3 wheel set up puts extra load on the solo wheel. If the solo wheel were to fail the sled is no longer mobile. By running a 4th wheel kit the load is evenly distributed on the rear axle, and should any one wheel fail the sled can still be ridden.
