Product Description

The FOX 980-24-665 2.0 Performance Series Rear Shock is engineered to significantly enhance rear suspension performance on lifted Ford Super Duty trucks. Featuring FOX's proven Internal Floating Piston (IFP) technology, this mono-tube shock maintains separation of shock oil and nitrogen gas to prevent aeration and deliver consistent damping over varied terrain and loads. The impact-extruded aluminum body dissipates heat effectively and resists corrosion, ensuring reliable long-term service.

Designed as a direct-fit performance replacement for select 2005-2016 Ford F-250 and F-350 Super Duty models equipped with approximately 4"-6" of rear lift, the 980-24-665 improves stability, ride control, and rear suspension articulation without sacrificing comfort. Its application-specific valving and high-flow piston deliver a controlled and predictable ride whether you're on-road or off-road.
