Fabtech’s 4 Link Conversion system for the 2017-21 Ford F250/F350 4WD (GAS) is engineered to enhance on-road performance while delivering the capability needed to conquer rugged offroad terrain. This premium bolt-on system replaces the factory Radius Arm suspension and includes all necessary components to convert the vehicle to a true 4 Link front suspension.
The 4 Link design reduces caster change throughout the suspension travel range, improving stability and control during on-road driving. Offroad, the system provides greater articulation compared to a Radius Arm setup, allowing the vehicle to navigate challenging terrain with increased flexibility and confidence at any speed.
Included with the system are Dirt Logic 2.25 Stainless Steel reservoir shocks for the front and non-reservoir shocks for the rear. These shocks are precisely ride-tuned to work with Fabtech Coil Springs and oversized tires, delivering exceptional ride quality both on and offroad.
Proven through more than a decade of service in military applications, Fabtech’s 4 Link System showcases high-quality components and properly engineered suspension geometry—making it the pinnacle of Super Duty suspension performance. The system also includes a free 5-year/60,000-mile powertrain warranty for added assurance.
Each Fabtech component is expertly built in-house and features specific design benefits as outlined below.
