Product Description

The FOX 985-24-121 is a 2.0 Performance Series front smooth body reservoir shock for select Ford Super Duty applications. It is designed for owners who want better front-end damping control, improved heat management, and more consistent ride quality than standard replacement shocks can provide, especially on trucks used for towing, hauling, rough-road driving, and off-road travel. The external reservoir increases oil and nitrogen capacity to help control heat during repeated suspension movement.

Verified FOX catalog data confirms front fitment for 2005-2016 Ford F-250 Super Duty 4WD and 2005-2016 Ford F-350 Super Duty 4WD with 2 to 3.5 inches of front lift. FOX also lists 2005-2010 F-450 and F-550 Super Duty front coverage for the same part number with the note that it includes a universal bracket. The stated lift amount applies to the front only; rear lift is not provided by this part number.

This part is sold individually, so 2x shocks are typically required for a full front axle installation. To stay accurate, this listing keeps the broader Super Duty fitment split by the year ranges that were explicitly shown in trusted source data rather than assuming one universal year span across every Super Duty model.
