Fitment, Shipping & Product Support
The Fox 2.0 Performance Series Front Shock (SKU 985-24-154) is engineered for the 2017–2024 Ford F-250 and F-350 Super Duty, running stock height to a modest front lift. 2.0" impact-extruded and CNC-machined 6061-T6 aluminum body — improves heat dissipation over steel-bodied OEM shocks and resists rust. Race-developed high-flow damping piston with application-specific valving tuned to the F-250/F-350 Super Duty chassis. IFP (Internal Floating Piston) mono-tube design separates shock oil from the nitrogen gas chamber, eliminating oil aeration for consistent damping through heat cycles during towing, hauling, and rough-road use. Sold as a single front shock.
This is the 2017+ Super Duty chassis only. For a 2005-2016/2017 Super Duty, a different Fox part number (985-24-120) is required.

Common Questions
Does this fit my 2015 F-350?
No. This part number is for the 2017+ redesigned Super Duty chassis only. A 2005–2016/2017 truck needs a different Fox part number (985-24-120).
Does this fit an F-450?
No. F-450 and F-550 use different front suspension geometry than F-250/F-350.
Do I need one or two?
This listing is for a single shock. Order quantity 2 for a complete front pair, and replace both sides together for balanced handling.
The Obsidian Take
The 985-24-154 is for the 2017–2024 F-250/F-350 Super Duty owner running at or near stock height who wants Fox's IFP damping and aluminum-body heat dissipation over the factory steel shock — direct bolt-on, application-specific valving for this exact chassis generation.
The check that matters most: confirm your truck is 2017 or newer. This part does not cover the earlier Super Duty generation, which requires a different Fox part number entirely.
Non-Returnable Notice: Once installed, this unit is non-returnable. Confirm model year and front lift height before ordering.
