The FOX 1.5 Zero QS3 Rear Track Shock, manufacturer part number 853-02-035 and vendor part number 853-02-035, is designed for select Ski-Doo mountain snowmobiles. It provides quick, glove-friendly suspension adjustment through FOX Quick Switch Technology, allowing riders to change settings without removing their gloves or counting individual clicks in cold conditions.
Three selectable positions help tailor the shock for changing terrain and riding demands. The rebound setting supports quicker recovery over consecutive impacts and can increase traction with additional preload. The lockout setting helps make side hilling easier and provides more predictable climbing by limiting weight transfer and reducing trenching. These adjustments deliver noticeable changes in ride feel and handling while maintaining straightforward operation on the trail or in deep snow.
Fitment includes the 2016 and 2017 Ski-Doo Summit Burton 800R E-TEC with 154-inch track; 2015 through 2017 Ski-Doo Summit SP 600 HO E-TEC with 146-inch track; 2015 through 2017 Ski-Doo Summit SP 800R E-TEC with 146-inch track; and the 2016 and 2017 Ski-Doo Summit Sport 600 Carb with 146-inch track. This FOX rear track shock is intended for compatible mountain rear-track applications only. Verify the model, engine, track size, and suspension configuration before ordering to ensure proper fitment.
