Fabtech 4" Radius Arm System with Dirt Logic 4.0 Coilover Conversion

If you own a 2011-2016 Ford F-250 or F-350 Super Duty, you already know that these trucks are built for both work and play. Fabtech's 4" Radius Arm System is engineered specifically for your Super Duty, delivering the heavy-duty performance you need to conquer both on and off-road challenges. This isn’t just an upgrade; it’s a transformation that enhances your truck's strength and capability.

Why Choose Fabtech?

At the core of this system are Fabtech's renowned tubular Radius Arms, designed with insights gained from racing. These arms feature a robust tubular structure, reinforced with dimple die side plates and heavy gusseting, ensuring they can handle the toughest terrains while outperforming the stock stamped arms in strength and durability.

Key Features

  • Dirt Logic 4.0 Coilover Conversion: Provides unmatched damping capacity for off-road adventures while maintaining a smooth ride on the pavement. This coilover bolts directly in place of your factory coil spring, eliminating the need to remove the coil spring bucket.
  • Corrosion Resistance: The Dirt Logic shocks are built with a stainless steel body to withstand the elements, paired with a massive 4" diameter aluminum remote reservoir that mounts above the coilover for optimal compression travel with oversized tires.
  • Rear Suspension Enhancements: Includes a 5" lift block, extended bump stop brackets, and Dirt Logic 2.25 shocks, ensuring a well-balanced ride quality that keeps you comfortable whether you're on the highway or tackling rough trails.
