Product Description

The Fox 985-24-149 2.0 Performance Series rear reservoir shock is a high-performance suspension upgrade engineered specifically for lifted Ford Super Duty trucks including F-250 and F-350 models from 2017 through 2025 with rear lift heights in the range of 1.5" to 3.5". Built with an external reservoir that increases oil and nitrogen capacity, this smooth-body shock provides enhanced cooling and consistent damping under demanding driving conditions. The Internal Floating Piston (IFP) design keeps gas separated from shock oil to minimize aeration for reliable performance over rough terrain or extended highway travel.

Constructed with a durable 2.0" impact-extruded aluminum body finished in clear anodizing, the 985-24-149 resists corrosion while efficiently dissipating heat for long service life. Precision-tuned valving paired with a race-developed high-flow piston delivers controlled rebound and improved ride quality whether hauling, towing, or off-roading. Sold individually with a CNC-machined reservoir clamp included, this shock is ideal for Super Duty owners seeking a direct-bolt performance upgrade for rear suspension on lifted trucks.
