Construction & Design

The Fabtech 6" Radius Arm System is constructed from high-strength tubular steel, providing exceptional durability and resistance to bending or fatigue under heavy use. The radius arms feature dimple die side plates that reinforce critical stress points, ensuring long-lasting performance in rugged environments. The system's design maintains proper suspension geometry, which is crucial for handling, steering, and tire wear. The coil springs and coilover shocks are engineered for optimal load support and damping, delivering a smooth ride both on and off-road. All components are precision-machined and TIG-welded for quality craftsmanship and a perfect fit, making installation straightforward and reliable.

This lift kit is designed to retain factory steering and suspension geometry as much as possible, reducing the need for additional modifications or alignment adjustments after installation. The use of heavy-duty materials and thoughtful engineering ensures that your truck remains dependable under demanding conditions, whether hauling heavy loads or navigating challenging trails.

Performance & Sound

With the Fabtech Radius Arm System installed, your Ford F250 will experience improved ground clearance, allowing for larger tires and better off-road capability. The system enhances overall suspension articulation, providing better traction and stability on uneven terrain. The optional Dirt Logic 4.0 Coilover shocks offer superior damping characteristics, resulting in a more controlled and comfortable ride during spirited driving or off-road adventures. While this lift kit is primarily focused on performance and durability, it also provides a commanding stance and aggressive appearance, giving your truck a more formidable presence.

Installation & Fitment

The Fabtech 6" Radius Arm System is designed as a bolt-on upgrade, making it accessible for experienced DIY enthusiasts and professional installers alike. The kit uses factory mounting points and requires no cutting or drilling in most cases, although some minor adjustments may be necessary for optimal fitment. The installation process typically involves removing the factory radius arms, shocks, and other suspension components, then replacing them with the new Fabtech parts. Due to the complexity of suspension lifts, professional alignment is recommended after installation to ensure proper handling and tire wear.
