Designed for the 2019-2022 Ford F450 and F550 4WD, Fabtech’s 6-inch 4 Link Conversion System is built to handle the demanding on-road and off-road requirements of Super Duty truck enthusiasts. The F450 and F550 feature a significantly more robust suspension than the F250 and F350, requiring specialized components engineered specifically by Fabtech.
This complete system includes everything required to convert the factory front suspension to a true 4 Link design. The 4 Link configuration minimizes caster change throughout suspension travel, resulting in improved highway stability and steering control. Off-road, the system delivers greater articulation than a traditional radius arm setup, allowing improved terrain traversal at all speeds.
Fabtech’s 4 Link System has been proven through more than 10 years of use in consumer, commercial, and military applications. Precision-engineered suspension geometry combined with high-quality components makes this system one of the most advanced Super Duty suspension solutions available.
Each Fabtech component is manufactured in-house and designed with specific features and benefits to deliver long-term durability, strength, and performance in extreme conditions.
