Designed for the 2017-2022 Ford F250/F350 4WD, Fabtech’s 8-inch 4 Link Conversion suspension system is engineered to deliver maximum suspension performance for both on-road driving and extreme off-road use. This advanced system replaces the factory radius arm suspension with heavy-duty 4 Link components to provide increased strength, control, and durability.
The 4 Link design significantly reduces caster change throughout the suspension travel, resulting in improved steering feel and stability on the road. Off-road, the system offers greater articulation than a radius arm setup, allowing the vehicle to traverse rugged terrain with confidence at any speed.
Unique to this 8-inch system is Fabtech’s exclusive extended-length track bar, designed to address the hyper-sensitive steering found in late-model Super Duty trucks. The track bar is 4 inches longer than stock and offset to the driver side using a heavy-duty 1/4-inch thick steel mounting bracket. This configuration keeps the track bar and drag link closer to parallel, reducing steering push and bump steer while allowing full steering lock with 15.50-inch wide tires on 4 3/4-inch backspace wheels.
Fabtech’s 4 Link system has been proven through more than 10 years of service in rugged commercial and military applications, ensuring long-term durability for daily-driven trucks. Precision-engineered suspension geometry and premium components make this one of the most advanced Super Duty suspension systems available. This system includes a free 5-year or 60,000-mile powertrain warranty.
Each Fabtech component is manufactured in-house and designed with specific features and benefits to deliver superior ride quality, steering control, and long-term reliability.
