Uses OEM parts.  Easy install for those who would like to add the 4th wheel between the rails of their 2019 + Arctic Cat or Yamaha that came with three 8" wheels on the 25mm axle shaft.


(Note: most 146" track models use the 7.12" wheel and cannot use this kit.)


SImply replace your existing long spacer tube and washer on the inner part of your axle with the included shorter spacer tube, wheel, and plastic wheel-axle spacer block.  No modification of existing parts.  Easy conversion back to original if desired.  ISR Stock class legal.


While you have your rear axle assembly apart, it is a great time to replace and upgrade your bearings as well!  You may want to add four of our high performance ceramic hybrid bearings to your order.  Part number 6005-2RS CH.
