FOX Performance Elite Series 2.5 shocks improve the stock 14th generation Ford F-150 platform by eliminating the vehicle’s forward rake, providing a level ride height, and increasing the suspension articulation of your truck. Type III anodization prevents corrosion and wear of the 2.5-inch aluminum bodies. External reservoirs increase oil capacity, remove dead space from the shock body, and decrease the harshness associated with nitrogen ramp-up. Cooler shock temperatures, more travel, and consistent damping forces result. Each reservoir features a Dual Speed Compression (DSC) adjuster; strategically mounted to eliminate interference with aggressive tires at full lock. Quickly adapt your shocks for load, environment, and driving style using the DSC adjusters as the high-flow piston manages stability through all types of terrain. FOX shocks are designed and engineered to support the damping of your rig with the presumption that you’re engaged in various activities. Realize the potential of your F-150 on the next adventure. Performance Elite shocks provide the versatility required to navigate rough terrain and improve on-road manners while remaining comfortable and in control.
