FOX Factory Race Series Internal Bypass DSC Rear Shock for 2018–2019 Jeep Wrangler JL, 3.5–4.5-Inch Lift, Part 883-26-078

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

Upgrade your 2018–2019 Jeep Wrangler JL with the FOX Factory Race Series Internal Bypass Piggyback DSC Rear Shock, Part 883-26-078. Developed from FOX off-road race shocks, this performance-tuned suspension component delivers race-proven damping control and improved ride quality for Jeeps equipped with a 3.5- to 4.5-inch suspension lift. Application-specific valving helps maximize performance across changing terrain, vehicle weight, and driving speeds.
FOX patented internal bypass technology creates multiple internal damping zones that regulate oil flow throughout the shock stroke. This design provides a controlled, comfortable ride through the ride zone while increasing damping support as suspension travel progresses. The integrated Dual Speed Compression adjustment allows fine tuning for low- and high-speed compression, helping drivers tailor suspension response for technical trails, high-speed terrain, and varying vehicle setups.
Built for demanding off-road use, the FOX Factory Race Series shock features a heat-dissipating aluminum body, black anodized CNC-machined aluminum components, an external piggyback reservoir, and a durable 7/8-inch shaft with redundant seals. The aluminum construction helps manage heat more efficiently than steel, while the reservoir and internal bypass design support consistent damping performance during extended, aggressive driving. This rear shock is engineered for strength and dependable operation in harsh off-road environments.
