We've designed this kit as an ultra-premium version of Arctic Cat part number 6639-621 (Yamaha # SMA-8JY47-00-BK). It is designed for the Pro Cross / Pro Climb rear suspensions 137" and longer that originally did not come with outer wheels on the rear axle (see below for fitment).
This kit contains:
- 2 - 8" Billet aluminum wheels with black powder coated accents. These wheels come with rubber installed on the outer edge to help prevent wheel wear and make them excellent for use on studded tracks.
- 2 - Ceramic Hybrid bearings. The wheels come with our high performance ceramic hybrid bearings pre-installed for minimum rolling resistance and maximum performance.
- 2 - Stand off wheel spacers CNC machined from 6061 aluminum
- 2 - CL10.9 fasteners with extra thick washers for maximum strength.
