FOX Performance Series 2.5 Reservoir Rear Shock for 2024–2026 INEOS Grenadier and 2025 Grenadier Quartermaster – Part Number FOX885-24-271

FOX Performance Series shocks contain the latest in shock technology to transform the performance of your Jeep. They use our race-proven damping control to provide a comfortable on-road ride and predictable off-road handling in even the toughest conditions. Application specific valving to maximize performance. Increase your vehicle's off-road capability by extending drop-out travel in most applications. Experience on-road comfort with performance-minded shock valving for a connected ride with less vehicle sway. Tuned specifically for your vehicle’s application. Consistent and fade-resistant performance due to high-quality materials: aluminum bodies, race-developed main piston, and a true internal floating piston (IFP) to separate gas and oil. Built-to-last, torture-tested and race-proven to give a lifetime of great rides. FOX products are built from aluminum, dissipating heat four times better than conventional materials. All FOX shocks are fully serviceable and resistant to corrosion and harsh environments.

• Performance Tuned For Vehicle Specific Application
• Aluminum Body Dissipates Heat Faster Than Steel
• Black Anodized CNC Machined Aluminum Components
• External Reservoir System Dissipates Heat Fast
• Includes Aluminum Reservoir Clamp

The FOX Performance Series 2.5 reservoir rear shock, part number FOX885-24-271, is engineered to improve suspension control and off-road capability for select 2024–2026 INEOS Grenadier models and 2025 INEOS Grenadier Quartermaster applications. Its vehicle-specific valving delivers a comfortable on-road ride, reduced body sway, and predictable handling when driving over challenging terrain.

Built with an aluminum body and black-anodized CNC-machined aluminum components, this FOX shock is designed to dissipate heat efficiently for consistent, fade-resistant performance. The race-developed main piston and true internal floating piston separate gas from oil, helping maintain damping control during demanding use. An external reservoir provides additional heat dissipation and supports reliable performance during extended off-road driving.

The FOX Performance Series shock is fully serviceable and designed to withstand corrosion, harsh environments, and repeated abuse. Its application-specific tuning helps maximize suspension performance while increased droop travel can improve wheel control in many vehicle configurations. An aluminum reservoir clamp is included for secure installation. This rear shock is intended for compatible 2024, 2025, and 2026 INEOS Grenadier models, along with select 2025 INEOS Grenadier Quartermaster applications. Professional installation is recommended, and exact fitment should be verified before ordering.
