This kit adds a 4th wheel kit to the axle and also eliminates all the plastic spacers on the rear axle. The billet outside spacers fully encapsulate the track tension adjuster bolts to reduce stress on the nut holders. In addition they prevent the adjuster bolts from making contact with axle directly which prevents nicks/burrs from occurring on the axle. The design also allows almost full use of the rail slot which yields more track adjustment range. Kit will work with OEM wheels and HD aftermarket wheels.
