Product Description

The Fox 985-24-174 2.0 Performance Series rear reservoir shock is engineered to upgrade the rear suspension damping on Ford Super Duty trucks from 2017 through 2025 with stock ride height or up to approximately 1" of lift. Featuring a smooth-body design with an external reservoir, this shock increases oil and nitrogen capacity for enhanced heat dissipation and consistent performance under varied driving conditions. Internal Floating Piston (IFP) technology helps separate gas from shock oil to minimize aeration and provide smooth, predictable damping during highway cruising or off-road use.

Constructed with a lightweight yet durable 2.0" impact-extruded 6061-T6 aluminum body with a clear-anodized finish, the 985-24-174 resists corrosion and efficiently manages heat for long service life. Its race-developed high-flow piston and vehicle-specific valving deliver improved control and handling over stock shocks, while quiet nitrile rubber bushings improve articulation and reduce noise. Sold individually with a billet aluminum reservoir clamp included, this rear shock is ideal for Super Duty owners seeking a direct-fit performance upgrade.
