Fox 2017+ Ford SD 2.5 Perf Elite Series Reservoir Shock Rear P/B 2-3.5in Lift (Pair) w/ DSC Adj.

What you get in this package are a pair of FOX Performance Elite Series 2.5 Reservoir Shocks, specifically designed for trucks with a 2 to 3.5-inch lift. These shocks are built using technology developed from off-road racing, bringing that proven performance to your daily driver or weekend adventure vehicle. They are tuned for specific truck applications to give you a noticeable improvement in comfort and control over various terrains, whether you're on the highway or tackling rougher roads.

The construction here is solid, featuring a 2.5-inch impact-extruded and CNC-machined 6061-T6 aluminum body with a durable black anodized finish. This, along with the external reservoir system, helps dissipate heat effectively by increasing oil capacity, which is crucial for maintaining consistent damping performance, especially during extended use or hard driving. The larger, high-flow piston is designed to increase resistance to bottoming out, giving you more confidence when you encounter larger bumps or dips. You also get a 7/8-inch hard chrome-plated steel shaft for durability and a redundant sealing system to keep contaminants out and fluid in.

A standout feature is the Dual Speed Compression (DSC) adjuster, which lets you fine-tune the damping characteristics for both low-speed and high-speed impacts. This allows you to dial in the ride for your specific needs, whether you prioritize a softer ride on the street or firmer control off-road. The remote reservoirs are mounted to ensure they clear aggressive tires, even at full steering lock, which is a practical consideration for many truck builds. These shocks are designed to unlock the full travel available in both jounce (compression) and droop (extension) positions, maximizing your suspension's potential.

These shocks fit a range of Ford Super Duty trucks from 2017 through 2025, including models like the F-250 and F-350 Super Duty. They are also compatible with the 2025 F-150, F-150 Lightning, Ranger, and Maverick. While these shocks are a significant upgrade on their own, remember to consult the manufacturer's installation instructions for any specific hardware or procedures recommended for your vehicle.
