FOX 883-26-099 2.5 Perf. Elite Front Shocks for 17-25 Ford F250/F350 w/4-6" Lift

Vehicle Fitment

• 2017-2025 Ford F-250 Super Duty (4WD, models equipped with front lift 4-6")
• 2017-2025 Ford F-350 Super Duty (4WD, models equipped with front lift 4-6")

Fitment Notes

• Designed specifically for vehicles with a **4-6" front lift**; additional suspension components (springs, leveling kits) required to achieve this lift height.
• Installation is for the front axle shock pair -- kit may include or coordinate with separate rear shock kit (883-26-100).
• 4WD models only; not intended for 2WD Super Duty trucks unless geometry and ride-height match specs.
• Mounting: top mount stem (front), bottom mount eyelet (front); verify for your specific year/trim.
• Shock kit does not include lift springs -- required separately if not already installed.

Features

• 2.5" (63.5 mm) CNC-machined aluminum shock body with remote or piggyback reservoir for maximum fluid capacity and heat dissipation
• Dual-Speed Compression (DSC) adjuster -- independent control of low-speed and high-speed damping (10 low-speed + 12 high-speed clicks)
• Impact-extruded 6061-T6 aluminum body with Type III anodized finish for corrosion resistance and strength
• 7/8" hard-chrome plated steel shaft for durability under extreme loads and terrain use
• Application-specific valving tuned for the Super Duty heavy-duty load, towing, and off-road usage scenarios
• Fully rebuildable internally -- designed for long service life and maintainability
• Extended travel range (front travel ~9.98") allowing improved wheel articulation and ride comfort on lifted platforms
• Includes all necessary hardware for mounting, instructions for setup, preload, and tuning guidelines

Product Description

The FOX Performance Elite 2.5" Reservoir Shock Kit (883-26-099) is engineered for the 2017-2025 Ford F-250/F-350 Super Duty 4WD trucks equipped with a 4-6" front lift. Designed from FOX's off-road race heritage, this kit features a 2.50" diameter CNC-machined aluminum body, remote reservoir, and dual-speed compression adjustability to deliver superior ride control, durability, and performance in demanding environments.

With nearly 10" of front travel and premium internal components, the 883-26-099 enhances wheel articulation off-road while maintaining refinement on the highway. It bolts directly into factory or lifted suspension systems (with required geometry matched) and allows fine-tuning of both low-speed ride comfort and high-speed damping for load, terrain, and driver preference. Confirmed fitment through 2025; 2026+ applications have not yet been officially validated.
