Ford F250 Suspension Lift Kit - Rear - Fabtech - 4in Rear Box Kit, Dirt Logic 4.0 Coilover, 4-Link Systems Radius Arm - `11-`16 is a rear suspension upgrade designed for owners who want improved ride control and durability for Ford Super Duty trucks. This kit pairs Fabtech’s proven rear box lift with Dirt Logic damping components to enhance handling on- and off-road.
The kit replaces stock rear components with a boxed lift block and bump stop relocation brackets while integrating Fabtech’s Dirt Logic 4.0 technology and 4-link/offset tubular radius arm options. The Dirt Logic 4.0 coilover features a stainless steel body and a NitroSteel piston rod for corrosion resistance and consistent damping. Fabtech’s radius arm options use a dimple die side plate and reinforced tubing for strength and to minimize caster change through suspension travel, improving tracking and ride quality under load.
