Designed for the 2017 Ford F450/F550 4WD, Fabtech’s 6-inch Radius Arm suspension system is engineered to handle the demanding on-road and off-road conditions required by heavy-duty Super Duty trucks. The F450 and F550 feature a more robust suspension platform than the F250 and F350, requiring specialized components developed exclusively by Fabtech.
This Radius Arm system is a complete upgrade to the factory suspension, providing increased strength and durability for use with oversized tires. The design has been proven through more than 10 years of service in consumer, commercial, and military applications, delivering reliable performance in the harshest environments.
Fabtech’s precisely engineered suspension geometry and high-quality components set this system apart from other radius arm designs. Each component is designed with specific features and benefits to improve ride quality, steering control, and overall suspension performance while maintaining proper driveline and steering geometry.
