FOX 883-26-083 Factory Race Series Rear Bypass Shock for 2020–2021 Jeep Gladiator with 3.5–4.5-Inch Lift

Developed from our off-road race shocks, FOX Factory Race Series combines race-proven technology with new, cutting-edge features to provide enhanced ride-quality and winning damping performance you can bolt onto your Jeep. Application specific valving to maximize performance. Uncompromised performance through FOX’s patented internal bypass technology delivers the feel of near-endless suspension travel. Exclusive internal bypass technology allows oil to flow around the piston at some points of the stroke – while creating humongous pressure at other points – supporting the vehicle like no other product can. Floating through terrain is accomplished with FOX’s ride zone – combining a race-developed shock piston, internal bypass and Dual Speed Compression adjustment – allowing fine tuning for weight, terrain and speed. Dominate any terrain with the brute strength of 3- and 2.5-inch aluminum bodies, cactus cooler reservoirs and 7/8” shafts with redundant seals, all proven in the harshest of environments under the toughest of conditions.

• 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
• Multiple Internal Damping Zones

The FOX Factory Race Series 883-26-083 rear shock is engineered for 2020–2021 Jeep Gladiator models equipped with a 3.5- to 4.5-inch suspension lift. Developed from FOX off-road race shocks, this application-specific replacement combines race-proven damping technology with advanced adjustability to deliver controlled handling, improved ride quality, and confident performance across demanding terrain. Vehicle-specific valving helps optimize the shock for the Gladiator platform, while the piggyback reservoir supports consistent performance during extended off-road use.
FOX patented internal bypass technology creates multiple damping zones throughout the shock stroke. This design allows oil to flow around the piston in selected areas while generating increased damping pressure where additional control is needed. The result is a more composed ride with improved bottom-out resistance and suspension behavior that remains predictable over changing terrain, vehicle loads, and speeds. The ride zone combines a race-developed piston, internal bypass operation, and Dual Speed Compression adjustment for precise tuning based on driving conditions and personal preferences.
Built for severe off-road environments, the FOX 883-26-083 features a durable aluminum shock body that dissipates heat faster than conventional steel construction. Black anodized, CNC-machined aluminum components provide long-term durability, while the external reservoir helps manage heat during repeated impacts and high-speed driving. A robust shaft and redundant sealing system support reliable operation in harsh conditions. This rear shock is designed for enthusiasts who want race-inspired performance, adjustable damping, and dependable control from a direct-fit FOX Factory Race Series upgrade for their lifted Jeep Gladiator.
