FOX Factory Race Series 3.0 Rear Internal Bypass Shock with DSC, Part 883-26-058, for 2018+ Jeep Wrangler JL with 2-3 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

Upgrade the rear suspension of your 2018 and newer Jeep Wrangler JL with the FOX Factory Race Series 3.0 Internal Bypass Shock, part number 883-26-058. Developed from FOX off-road race shocks, this application-specific shock combines race-proven technology with advanced damping control to improve ride quality, handling, and performance on demanding terrain. Vehicle-specific valving helps maximize suspension performance for the Jeep Wrangler JL with a 2- to 3-inch lift.
FOX’s patented internal bypass technology creates multiple damping zones throughout the shock stroke. Oil flows around the piston in selected areas for a controlled, compliant ride, then encounters increased resistance where additional support is needed. The result is suspension performance designed to deliver smooth operation over changing terrain while maintaining control during aggressive driving. The integrated Dual Speed Compression adjustment allows drivers to fine-tune damping for vehicle weight, terrain, and speed.
Built for severe off-road use, the shock features a durable aluminum body that dissipates heat faster than steel, along with black anodized, CNC-machined aluminum components. The external reservoir system improves heat management during extended operation, while the robust shaft and redundant sealing system provide dependable performance in harsh environments. Multiple internal damping zones further support consistent control throughout the suspension cycle.
