Construction & Design

The Fabtech 6-inch Radius Arm System utilizes heavy-duty tubular steel for the radius arms, which are reinforced with dimple die side plates to resist bending and torsion. The adjustable cam at the axle allows for fine-tuning of caster, ensuring proper steering response and tire contact patch. The coil springs are engineered to provide a smooth ride while supporting the added lift, and the optional Dirt Logic 4.0 Coilover shocks are designed for aggressive off-road performance with improved damping characteristics.

The system's components are TIG-welded for superior strength and precision, and the overall design maintains factory-like handling characteristics. The inclusion of sway bar drops and a trac bar relocation bracket ensures proper suspension geometry, preventing unwanted axle movement and ensuring stability during spirited driving or off-road adventures.

Performance & Sound

This suspension upgrade significantly improves ground clearance and off-road capability, allowing your Ford F250 to conquer challenging terrain with ease. The increased wheel travel and improved geometry translate into better handling, stability, and control. While specific horsepower or torque gains are not claimed, the system helps support the vehicle's overall performance by maintaining proper alignment and suspension geometry after lifting.

Installation & Fitment

The Fabtech Radius Arm System is designed as a bolt-on upgrade, making installation straightforward for experienced DIY enthusiasts or professional installers. The kit uses factory mounting points and does not require cutting or drilling, ensuring a clean and precise fit.
