Fabtech 17-20 Ford F250/350 4WD Diesel 4in Rear Box Kit

Fabtech takes their 4 in. Super Duty systems to the next level with the release of the Dirt Logic 4.0 Coilover Conversion. This bolt on Coilover conversion will transform the ride quality of the Super Duty while providing outstanding damping capacity for rugged offroad use. The Dirt Logic 4.0 Coilover is constructed with a stainless steel body and a NitroSteel piston rod for maximum corrosion resistance. This 4 in. lift Coilover Conversion is offered with Fabtech's Tubular Radius Arm or 4 Link Systems Radius Arm system features an offset tubular design with dimple die side plate for maximum strength. The 4 Link system replaces the stock Radius Arms for an improved ride quality both on and offroad due to a near zero caster change throughout the suspension travel. Both systems include a track bar relocation bracket to center the front Super Duty axle under the vehicle with the new lift height. Rear lift comes from a 5 in. lift block with bump stop relocation brackets. Rear Dirt Logic 2.25 stainless steel shocks are valved to provide a balanced ride to the Super Duty for the finest on road ride quality. These high end 4 in. Systems are the pinnacle of quality and ride performance for the Super Duty. Each system is a bolt on installation and comes with Fabtech's 5 year 60,000 mile warranty.
