Performance Suspension Upgrade. The FOX 4-6in Lift Rear 2.5 shock is engineered to enhance ride quality and control for lifted trucks. It offers superior damping performance on and off-road using position-sensitive technology, resulting in a smoother and more comfortable driving experience—especially with larger tires and lifts that exceed OEM specifications.

Construction and Appearance. Featuring a 2.5-inch impact-extruded 6061-T6 aluminum body with Type II clear anodizing, this shock resists corrosion and quickly dissipates heat. It includes a robust 5/8-inch hard chrome shaft and an internal floating piston (IFP) that separates oil from high-pressure nitrogen to minimize aeration and maintain consistent damping performance. The hydraulic top-out piston further refines rebound control at the end of the shock’s travel.

Installation. The FOX 2.5 Performance Series shock is a direct bolt-on replacement requiring no drilling or modifications. The top and bottom eyelet mounts ensure easy installation with compatible lift kits.

Warranty. This product is backed by a comprehensive warranty that protects against defects and ensures lasting performance.

Application. Designed specifically for 2017 through 2026 4WD Ford F-350 Super Duty models with 4-6 inch rear lifts, this shock provides optimized suspension performance and ensures compatibility with these trucks.
