Fabtech’s 4 Link Conversion system for the Ford Super Duty is engineered to improve on-road handling while giving superior off-road capability. This bolt-on replacement for the factory radius arm suspension converts the front end to a 4-link layout and includes all required components for the conversion.
Key benefits: Reduced caster change through suspension travel for better on-road driving, increased articulation for improved off-road terrain traversal, and ride-tuned shock and spring combinations for balanced comfort and control.
Fabtech’s 4 Link System draws on extensive field-proven designs used in demanding applications. Components are specifically designed for optimized suspension geometry and are matched together—coil springs and Dirt Logic shocks are tuned to work with oversized tires for excellent ride quality both on- and off-road. The system includes a 5 year, 60,000 mile powertrain warranty.
*Installation and compatibility notes: Non-dually models only. Not compatible with gasoline engines. Vehicles with a two-piece driveshaft may require an additional or replacement driveshaft component. Some 2017 models may require a dual steering stabilizer when using oversized tires.
