• Front spring lift options include 6-inch replacement coil springs, providing the desired lift height while maintaining ride quality and load support.
• Complete system includes a Trac Bar relocation bracket, Pitman arm, sway bar drops, and a rear block & U-bolt kit, ensuring proper geometry and alignment after lift installation.
• Supplied with Dirt Logic shocks, these high-performance shocks are engineered for off-road durability and improved damping, delivering a smooth ride over rough terrain.
• Heavy-duty construction and precision engineering ensure compatibility with factory components and ease of installation.
• Designed to support larger tires and wheels, enhancing both aesthetics and off-road capability.
• Manufactured in the USA, ensuring quality and adherence to strict standards for performance parts.

Construction & Design

The Fabtech Radius Arm System features a robust tubular design for the radius arms, providing exceptional strength and resistance to bending or fatigue under heavy loads and demanding off-road conditions. The dimple die side plates add extra reinforcement, further enhancing durability. The system's components are engineered with precision CAD modeling and TIG welding to ensure perfect fitment and long-lasting performance.

The adjustable cam at the axle allows for fine-tuning of caster angle, which is critical for maintaining proper steering response and tire wear. The included coil springs are designed to provide a balanced lift and ride quality, supporting both daily driving and off-road excursions. The shocks are specifically tuned for off-road use, offering superior damping and control over rough terrain.

Performance & Sound

This suspension system significantly improves ground clearance and off-road capability, allowing you to tackle challenging trails with confidence. The upgraded shocks provide better control and stability, reducing body roll and improving handling during spirited driving or heavy loads. While specific horsepower or torque gains are not claimed, the system supports increased load capacity and enhances overall vehicle performance in demanding conditions.

The ride remains comfortable on paved roads, with the shocks and spring setup designed to absorb bumps and vibrations effectively. The system's robust construction ensures long-term reliability and consistent performance, making it a trusted choice for off-road enthusiasts and heavy-duty users alike.

Installation & Fitment

The Fabtech 6" Radius Arm System is a bolt-on upgrade that requires no cutting or welding for installation. It uses factory mounting points and components, simplifying the process and reducing installation time. Basic mechanical skills and standard tools are sufficient for a professional-quality installation. It is recommended to perform a wheel alignment after installation to ensure optimal handling and tire wear.

Some minor adjustments may be necessary to achieve perfect alignment, but no specialized modifications are required. The system is designed to integrate seamlessly with your existing suspension components, providing a reliable and durable lift solution.
