This kit is specifically designed to reduce the Hyfax wear and drag on the rail of your Yamaha snowmobile. A wheel is placed on each rail at the point of greatest wear, extending Hyfax life and reducing friction for better performance.
Kit includes two wheels, mounting brackets, hardware and instructions for easy installation.
The more studs you use and the faster you corner, the more side force is transmitted into the track and the more tendency it has to derail. With the 4th rear wheel kit the two center wheels are positioned where they run between the internal drive lugs which act as guides and help keep your track from derailing, running straight and efficient. Recommended any time the track is studded. Comes complete with one plastic idler wheel, bearing, and aluminum spacers. These hyfax are made from a multi-compound mixture which reduces sliding friction on the guide clips of the track.
