Part #: K2243DL

Overview

The Fabtech 6" Radius Arm System with optional 2.5" & 2.25" lift options is a comprehensive suspension upgrade designed specifically for Ford F250 and F350 trucks from 2017 to 2021. Built to enhance off-road capability, improve ride quality, and support larger tires, this system is ideal for enthusiasts who demand durability and performance from their heavy-duty diesel trucks.

Whether you're tackling rugged trails, hauling heavy loads, or simply looking to elevate your truck's stance, this radius arm system provides a robust solution that maintains factory-like handling and stability. The system's design ensures your vehicle can handle challenging terrains while offering a commanding presence on the road.

Key Features

Fabtech's patented Radius Arms are engineered with strength and precision in mind. Constructed from full tubular steel, these arms are reinforced with dimple die side plates, providing exceptional durability and resistance to bending or flexing under heavy loads. The adjustable alignment cam at the axle allows for precise caster adjustments, ensuring optimal steering geometry and tire wear.

• Heavy-duty tubular steel construction with dimple die side plates for increased strength and longevity.
• Adjustable caster alignment cam for precise wheel alignment and handling.
• Includes a Trac Bar relocation bracket to maintain proper axle positioning during lift.
• Comprehensive kit with Pitman Arm, sway bar drops, and a rear block & u-bolt kit for complete suspension enhancement.
• Designed and manufactured in the United States, ensuring quality and craftsmanship.
• Optimized for diesel-powered trucks with 4WD drivetrain for off-road and towing performance.
• Supports larger tires and wheels, giving your truck a commanding stance and improved ground clearance.
• Maintains factory ride quality while providing increased suspension travel and articulation.
• Easy bolt-on installation with all necessary hardware included, no cutting or welding required.

Construction & Design

The Fabtech Radius Arm System features precision-engineered components crafted from high-strength tubular steel, ensuring maximum durability under demanding conditions. The dimple die side plates add extra reinforcement to the radius arms, preventing deformation and extending service life. The adjustable cam at the axle allows for fine-tuning of caster angles, which is critical for maintaining proper steering response and tire wear after lifting the vehicle.

The inclusion of a Trac Bar relocation bracket ensures that the axle remains centered during suspension articulation, preventing unwanted side-to-side movement. The Pitman Arm and sway bar drops are designed to restore factory steering geometry and handling characteristics, even with the increased lift height. All components are finished with a durable coating to resist corrosion and environmental damage, making this system suitable for off-road adventures and daily driving alike.

Performance & Sound

This suspension upgrade significantly improves off-road capability by increasing ground clearance and suspension travel. The robust radius arms and supporting components help support larger tires, which enhance traction and obstacle clearance. While this system is primarily designed for durability and performance, users may notice a slight increase in ride height and a more aggressive stance.

Handling remains predictable and stable, with improved steering response thanks to the adjustable caster cam. The system does not alter the factory noise levels significantly but provides a more commanding and confident driving experience both on and off the pavement.

Installation & Fitment

The Fabtech 6" Radius Arm System is a bolt-on upgrade that requires no cutting, welding, or major modifications. The kit is designed to fit directly onto your Ford F250 or F350 4WD diesel trucks from 2017 to 2021, restoring factory alignment and handling characteristics after lift installation. Basic mechanical skills and standard tools are sufficient for installation, which can typically be completed within a few hours.

• All necessary hardware and components are included for a complete installation.
• Designed for easy bolt-on installation with factory mounting points.
• No additional tuning or alignment adjustments are required beyond the caster alignment cam.
