Construction & Design

The Fabtech Radius Arm System features heavy-duty, fully tubular radius arms constructed from high-strength steel, reinforced with dimple die side plates for added durability. The adjustable cam at the axle allows for fine-tuning caster angles, which is critical for maintaining proper steering geometry after lifting. The 8-inch coil springs are engineered to provide a balanced lift, supporting increased ground clearance without sacrificing ride quality or load capacity.

The inclusion of a Trac Bar relocation bracket ensures the axle remains centered and stable during off-road excursions and spirited driving. The rear add-a-leafs and block & U-bolt kit are designed to complement the front lift, providing a level stance and improved suspension travel. All components are TIG-welded and manufactured to exact specifications, ensuring a precise fit and long-lasting performance.
