FOX® 2.5 Performance Elite Rear Shock Pair for 2021-2026 Ford F150 883-26-122

Description

Part number 883-26-122 is the FOX® 2.5 Performance Elite Series external reservoir rear shock pair for 2021-2026 Ford F-150 trucks running 0″-1″ of rear lift. Each shock uses a 2.5-inch Type III anodized 6061-T6 aluminum body, application-specific springs and valving, and an externally mounted reservoir with a Dual Speed Compression (DSC) adjuster.

IMPORTANT: Trim-year coverage is not uniform across the full 2021-2026 range. Limited trim is covered for 2021-2023 only, and Police Responder is covered through 2025. STX coverage begins in 2024. Confirm your specific trim and model year against the fitment section below before ordering.

This shock pair is engineered specifically for the 14th-generation F-150 platform to correct the stock forward rake, level ride height, and increase rear suspension articulation without altering the truck’s factory geometry.

The 2.5-inch impact-extruded, CNC-machined aluminum body is Type III anodized for corrosion and wear resistance. The external reservoir increases oil capacity, removes dead space from the shock body, and reduces the harshness associated with nitrogen ramp-up as the shock compresses, resulting in cooler operating temperatures and more consistent damping through longer travel.

Each reservoir carries a Dual Speed Compression (DSC) adjuster, positioned to clear aggressive tire sidewalls at full steering lock. The DSC adjuster lets the owner tune compression damping for load, terrain, and driving style without removing the shock from the vehicle. A high-flow piston manages stability across pavement, washboard, and rough off-road terrain.

Construction includes a 7/8″ hard chrome-plated steel shaft, a redundant three-stage sealing pack (main seal, wiper seal, scraper seal), and a rear shaft boot to protect against roost spray. Eyelet top and bottom mounts are standard. FOX backs the Performance Elite Series with its Truck & Motorsports product warranty.
