Construction & Design

The Fabtech Radius Arm System features a robust tubular construction, providing exceptional strength while maintaining a relatively lightweight profile. The dimple die side plates add reinforcement to critical stress points, preventing flex and deformation under heavy loads or off-road impacts. The system's design preserves factory-like handling and ride comfort, thanks to precisely engineered components and high-quality coil springs.

The inclusion of adjustable cam bolts allows for fine-tuning caster angles, which is essential for maintaining proper steering geometry after lifting the vehicle. The system's components are TIG-welded and CAD-designed for perfect fitment and durability, ensuring long-lasting performance even in the most challenging conditions.
