Product Details

Designed for the 2011-2016 Ford F350 4WD, this suspension system features Fabtech’s patented Radius Arms built with a full tubular structure and reinforced with dimple die side plates for maximum strength and durability. An adjustable alignment cam at the axle allows precise caster adjustment to maintain proper steering geometry with increased ride height.

Front lift is achieved using Dirt Logic 4.0 coilover shocks, delivering excellent off-road damping performance while maintaining a controlled and comfortable highway ride. The system also includes a track bar relocation bracket, dropped pitman arm, and sway bar drop brackets to ensure correct steering and suspension operation.

Rear lift is provided through a durable block and U-bolt kit, offering balanced stance, reliable load handling, and long-term durability. This complete system is engineered to deliver improved performance, strength, and control for both on-road driving and off-road use.

Our patented Radius Arms feature a full tubular structure strengthened by dimple die side plates with an adjustable alignment cam at the axle to allow caster adjustment. Front spring lift options includes 6 replacement

REAR DIRT LOGIC 2.25 SHOCK

Dirt Logic 2.25’s are designed to replace factory shocks with a larger, more robust configuration. The 2.25 size is what separates it from other replacement take apart shocks for a superior ride, both on and off road. Shocks are pretuned for each Fabtech suspension, accounting for larger tires, providing the finest all around damping.
