Product Description

The King Shocks 25001-171A Rear Adjustable Shock Set is a premium suspension upgrade for 4WD Ford Super Duty trucks - specifically F-250 and F-350 models from 2005 through 2025. These performance-tuned 2.5" shocks feature external piggyback reservoirs and a wide-range adjustable compression damper, providing enhanced control over rough terrain, highway driving, or when towing and hauling heavy loads. Enhanced fluid capacity and heat dissipation help maintain smooth and consistent damping performance in demanding conditions.

Built with high-quality materials and precision engineering, these shocks bolt directly into the rear suspension using factory mounting points and are fully serviceable and rebuildable for long-term use. Whether you're upgrading stock suspension for daily driving comfort or pairing with lift kits for off-road capability, King's adjustable rear shocks help improve stability, articulation, and overall ride quality on Ford Super Duty trucks.
