Designed for the 2017 Ford F450/F550 4WD, Fabtech’s 6-inch 4 Link Conversion suspension system is engineered to handle demanding on-road and off-road conditions. The F450 and F550 feature a significantly more robust suspension platform than the F250 and F350, requiring specialized heavy-duty components developed exclusively by Fabtech.
This system includes everything required to convert the factory front suspension to a true 4 Link configuration. The 4 Link design reduces caster change throughout the suspension travel, resulting in improved on-road handling and stability. Off-road, the system delivers increased articulation compared to a radius arm suspension, allowing better terrain control 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 delivers exceptional durability, ride quality, and long-term reliability.
Each Fabtech component is manufactured in-house and designed with specific features and benefits to create one of the most advanced Super Duty suspension systems available.
