Overview
The FOX Performance Series 2.0 Reservoir Front Shock is engineered for 2017–2026 Ford F-250 and F-350 Super Duty 4WD trucks equipped with 5.5 to 7 inches of front lift. Designed for lifted trucks that see everything from daily driving to towing and aggressive off-road use, this premium monotube shock delivers race-proven performance with exceptional ride quality and fade resistance. The external reservoir increases oil and nitrogen capacity to improve cooling and maintain consistent damping during extended use, while FOX's application-specific valving provides outstanding control over rough terrain.

Construction & Design
FOX builds the Performance Series 2.0 Reservoir Shock using an impact-extruded 6061-T6 aluminum body that dissipates heat significantly faster than traditional steel shocks. The external reservoir increases fluid volume to improve cooling and reduce fade, while the Internal Floating Piston keeps the shock oil and nitrogen charge separated for consistent damping performance. A hard-chrome steel shaft, precision-machined billet aluminum components, and redundant sealing system provide exceptional durability in demanding off-road and towing environments.
Driving Feel & Feedback
Designed specifically for lifted Super Duty trucks, the FOX 2.0 Reservoir Front Shock provides improved steering control, reduced front-end dive, and greater suspension stability over rough roads and uneven terrain. The race-developed high-flow piston and application-specific valving deliver a controlled, predictable ride while the external reservoir minimizes heat buildup during long trail rides, towing, or heavy hauling. Whether on the highway or off-road, drivers will experience improved confidence and reduced suspension fatigue.
