This system provides a significant lift to enhance off-road capability, improve ground clearance, and support larger tires, making it ideal for enthusiasts who demand durability and performance both on and off the pavement.

Built with quality and precision, this kit transforms your truck’s suspension to handle rugged terrain while maintaining a smooth, controlled ride. Whether you're tackling challenging trails or upgrading for a bold new look, this system offers the strength and adjustability you need to customize your vehicle’s stance and handling.

Key Features

The Fabtech Radius Arm System is engineered with advanced materials and innovative design features to deliver superior performance and durability. Here are some of the key attributes:

• Full tubular radius arms reinforced with dimple die side plates provide increased strength and rigidity, ensuring long-lasting performance under heavy loads and off-road conditions.
• Adjustable alignment cam at the axle allows for precise caster adjustments, helping you fine-tune your vehicle’s alignment for optimal handling and tire wear.
• The front lift is achieved through the Dirt Logic 4.0 Stainless Steel Coilover Shock conversion, offering adjustable damping and improved ride quality both on and off-road.
• Includes a Trac Bar relocation bracket, Pitman Arm, sway bar drops, and other essential components to ensure proper geometry and steering response after lift installation.
• Rear lift is supported by a block & u-bolt kit, providing a balanced stance and additional ground clearance.
• Supplied with front and rear 2.25-inch Dirt Logic Stainless Steel shocks, designed for durability and consistent performance in demanding environments.
• All components are engineered for easy bolt-on installation, reducing downtime and ensuring a secure fitment.

Construction & Design

The Fabtech Radius Arm System features heavy-duty tubular steel components that are TIG-welded for strength and precision. The dimple die side plates add structural integrity, preventing flex and ensuring longevity. The stainless steel coilover shocks are corrosion-resistant, making them suitable for off-road adventures and harsh weather conditions. The system’s design maintains factory steering geometry as much as possible, preserving drivability and minimizing wear on other suspension parts.

Every component is carefully engineered with CAD software to ensure perfect fitment and performance. The inclusion of adjustable features allows for customization based on your specific driving needs and preferences, whether for aggressive off-road use or street-driven applications.

Performance & Sound

With this suspension upgrade, expect improved ground clearance, better approach and departure angles, and enhanced off-road stability. The Dirt Logic 4.0 coilovers provide adjustable damping, allowing you to tailor the ride quality to your preferences. The upgraded shocks and reinforced radius arms work together to deliver a smoother, more controlled ride over rough terrain, while also supporting increased load capacity.

The system does not significantly alter the vehicle’s sound profile but offers a more confident and composed driving experience both on and off-road.

Installation & Fitment

The Fabtech 6" Radius Arm System is designed as a bolt-on upgrade, making installation straightforward for experienced DIY enthusiasts or professional installers. The kit includes all necessary hardware and brackets for a complete upgrade. No cutting, drilling, or welding is required in most cases, and factory mounting points are used to ensure a secure fit. Proper alignment is recommended after installation to maximize handling and tire life.
