**Yamaha or Arctic Cat Spring Track Skid Parts** **UPDATE:** March 2nd, 2020 - A new version for the Arctic Cat M8000 has been made. **Infos:** - The springs used are RC4WD's internal springs, specifically Z-S1183. - Dimensions of these springs are a diameter of 5.5 to 6.5mm and a length of 35 to 40mm. - It is highly recommended that you use the optional promod_rear_sprocket_bearing_v2.stl file to prevent excessive wear on your wheels. - Flanged bearings measuring 3x10x4 are used in this design. - Make sure to file or sand the "pushrod" so it can move freely within the rail's channels. - Avoid overtightening the sprocket screws as this will lock up the tensioner and cause problems. - Adding a small washer on each side between the rails and sprockets provides increased slippyness. - A bonus of having some flex when jumping and landing on the tip of the skid has been added.
