Key Features of FOX Performance Elite Series 2.5 Reservoir Shocks

Performance-Tuned for Maximum Control
The Performance Elite Series 2.5 Reservoir Shocks are specifically tuned to offer superior damping control, ensuring optimal handling for your truck or SUV. Whether you're off-roading or driving on highways, these shocks provide a smooth ride and precise performance. Their bolt-on design allows for easy installation on most stock and lifted vehicles.

External Reservoir for Enhanced Cooling
The external reservoir increases the shock’s oil and nitrogen capacity, effectively preventing shock fade during extended off-road use. This feature improves heat dissipation, ensuring consistent damping performance and allowing you to tackle tough terrain with confidence.

Durable, Hard-Anodized Aluminum Body
Crafted from a 2.5" impact-extruded and CNC-machined 6061-T6 aluminum body, these shocks are designed to resist rust and corrosion over time. The hard-anodized finish enhances durability, ensuring your suspension system maintains peak performance in rugged conditions.

Built for Strength and Reliability

7/8" Hard Chrome-Plated Steel Shafts for Maximum Durability
The 7/8" hard chrome-plated, heat-treated alloy steel shafts provide superior strength, allowing for smooth operation even in extreme environments. These heavy-duty shafts are built to withstand intense impacts, ensuring long-lasting performance.

Application-Specific Valving for Optimized Performance
Each shock is performance-tuned with application-specific valving, delivering a perfect balance of control, handling, and comfort tailored to your vehicle. Experience a stable and smooth ride, regardless of the driving conditions.

Redundant Sealing Pack System for Maximum Protection
The redundant sealing pack system includes a main seal, wiper seal, and scraper seal, providing multiple layers of protection against dirt, debris, and moisture. This advanced sealing system helps maintain smooth performance and extends the life of your shocks, even in challenging environments.
