Fabtech 11-16 Ford F350/450 4WD 8 Lug 6in Rad Arm Sys w/Dlss 4.0 C/O& Rr Dlss

If you're looking to significantly improve the off-road capability and stance of your 2008-2016 Ford F-350 Super Duty, this 6-inch Radius Arm lift system from Fabtech is a comprehensive solution. It's designed to provide maximum front suspension damping, especially when tackling rough terrain. The system replaces key factory components to allow for larger tires and improved suspension travel.

At the heart of the front suspension upgrade are the Dirt Logic 4.0 Stainless Steel Coilover Conversion units. These replace your stock coil springs and mounts with robust upper mounts made from 1.75-inch diameter DOM tubing, engineered to distribute impact loads across a wide frame section. The lower mounts are constructed from thick 1/4-inch steel and attach directly to the axle, providing a solid foundation for the heavy-duty coilovers. The system also includes Fabtech's patented Radius Arms, which feature a full tubular structure reinforced with dimple die side plates. An adjustable alignment cam at the axle allows for precise caster adjustments, crucial for proper wheel alignment after lifting. To complete the front, you get replacement front springs that provide the 6-inch lift, a Trac Bar relocation bracket, a Pitman arm, and sway bar drops.

The rear of your F-350 is addressed with a block and U-bolt kit to achieve the desired lift height, along with 2.25-inch Dirt Logic Stainless Steel shocks for consistent damping. This kit also includes billet sway bar end links with heim ends for improved articulation and quad-layer limiting straps to prevent over-extension of the suspension. This is a complete system designed to work together, offering a substantial upgrade for your Super Duty's performance and appearance.
