FOX Race Series 3.0 Internal Bypass Reservoir Rear Shocks for 2019+ Chevrolet Silverado 1500, 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 lifted truck with FOX Race Series 3.0 Internal Bypass Reservoir Shocks, part number FOX883-26-105. Developed from FOX off-road race shocks, this application-specific suspension system delivers controlled damping, improved ride quality, and race-proven performance for demanding driving conditions. The shocks are designed for 2019 Chevrolet Silverado 1500 and 2019 GMC Sierra 1500 applications equipped with a 2–3 inch lift.

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 increasing damping force where additional control is needed, helping provide a smooth, composed ride across changing terrain. The FOX ride zone combines a race-developed piston, internal bypass architecture, and Dual Speed Compression adjustment for tuning based on vehicle weight, terrain, and driving speed.

Built for severe off-road use, the FOX Race Series shocks feature an aluminum body that dissipates heat faster than steel, black-anodized CNC-machined aluminum components, and an external reservoir system for improved thermal management. A 7/8-inch shaft with redundant seals adds durability in harsh environments, while application-specific valving helps optimize suspension performance for the vehicle.
