Ford F350 Suspension Lift Kit - Rear - Fabtech - 4in Rear Box Kit, Dirt Logic 4.0 Coilover, 4-Link Systems Radius Arm - `11-`16. This Fabtech rear lift package combines a 4in rear box kit with Dirt Logic suspension components and upgraded radius arm options to improve heavy-duty ride control and off-road damping for 2011–2016 Super Duty trucks.
The kit pairs Fabtech’s Dirt Logic 4.0 coilover conversion — built with a stainless steel body and NitroSteel piston rod for corrosion resistance — with Fabtech’s choice of a Tubular Radius Arm or 4-Link Systems Radius Arm. The 4-Link design replaces the factory radius arms and is engineered to minimize caster change through suspension travel for more consistent handling on- and off-road. Rear lift is provided by Fabtech’s rear block kit and includes bump stop relocation brackets. Rear Dirt Logic 2.25 stainless steel shocks are valved to deliver a balanced on-road ride while still standing up to rugged use. The system is designed as a bolt-on installation and is covered by Fabtech’s 5 year / 60,000 mile warranty.
