FOX Burandt Series 1.5 FLOAT 3 QS3 Front and Rear Shock Kit 853-21-022 for Polaris Pro-RMK

WPS now offers Burandt Series Shock Kits! Developed in collaboration with professional snowmobiler Chris Burandt, these shocks are specifically tuned to his aggressive riding style. The series includes various models, such as the 1.5 ZERO QS, 1.5 FLOAT 3 EVOL QS, each offering unique features to suit different riding preferences and conditions.

The FOX Burandt Series 1.5 FLOAT 3 QS3 Front and Rear Shock Kit is developed in collaboration with professional snowmobiler Chris Burandt and tuned for aggressive mountain riding. Manufacturer part number 853-21-022 is designed for select Polaris Pro-RMK Matryx snowmobiles and includes front and rear track shocks for a complete suspension upgrade.

FOX QS3 technology provides three compression adjustment settings, allowing riders to quickly adapt shock performance to changing terrain and riding conditions. Position-Sensitive Damping uses spiral groove bypass technology to deliver a controlled, compliant ride through the initial portion of travel while increasing bottom-out resistance during the final portion of the stroke. This design helps maintain handling and suspension control during aggressive maneuvers, technical mountain riding, and hard landings.

FOX Ice Scraper Technology (FIST) helps limit snow and ice buildup around the shock, supporting consistent performance in cold and deep-snow conditions. The FOX Burandt Series kit fits 2022 Polaris 850 Pro-RMK Matryx 155-inch, 2022 Polaris 850 Pro-RMK Matryx Slash 155-inch 2.75-inch, 155-inch 3-inch, 163-inch 3-inch, and 165-inch 2.75-inch models.
