Construction & Design
FOX engineers the Performance Series 2.0 Reservoir Shock using a lightweight 6061-T6 aluminum monotube body, providing superior heat dissipation compared to conventional steel-body shocks. The external reservoir significantly increases fluid capacity while the Internal Floating Piston separates shock oil from the nitrogen charge to eliminate aeration and maintain consistent damping. A hard-chromed alloy steel shaft and redundant sealing system ensure exceptional durability in harsh environments, while application-specific valving is optimized for the weight and suspension characteristics of the Ford Super Duty.
Driving Feel & Feedback
Compared to the factory shocks, the FOX Performance Series Reservoir Shock provides improved control over rough terrain, reduced body motion, and greater stability when towing or hauling heavy loads. The increased oil volume and superior cooling allow the shock to maintain consistent damping during prolonged use, minimizing fade on washboard roads, rocky trails, or long highway drives with a trailer. Drivers will notice a smoother, more controlled ride and increased confidence in demanding conditions.
Installation & Fitment
The FOX Performance Series 2.0 Reservoir Rear Shock installs directly in place of the factory rear shock using the original mounting locations. No modifications are required, making installation straightforward for experienced DIY enthusiasts or professional installers. After installation, verify all hardware is torqued to factory specifications before operating the vehicle.
