Product Details

This suspension system is engineered to deliver increased ride height, improved strength, and enhanced suspension geometry for off-road and on-road performance. The system features Fabtech’s patented Radius Arms designed to provide superior durability and precise alignment control.

The full tubular Radius Arms are reinforced with dimple-die side plates for added rigidity and strength. An adjustable alignment cam is integrated at the axle, allowing for caster adjustment to properly dial in alignment after lifting the vehicle. This design improves handling, steering feel, and overall drivability.

Front lift is achieved using Fabtech replacement coil springs that provide consistent lift and controlled ride characteristics. Supporting components including a track bar relocation bracket, drop pitman arm, and sway bar drop brackets ensure correct steering geometry, axle positioning, and sway bar operation throughout the suspension travel.

Rear lift is accomplished using a block and U-bolt kit to level the vehicle stance while maintaining load-carrying capacity and ride quality. This complete system delivers a balanced suspension upgrade with improved ground clearance, strength, and reliable performance.

Our patented Radius Arms feature a full tubular structure strengthened by dimple die side plates with an adjustable alignment cam at the axle to allow caster adjustment. Front spring lift options includes 6 replacement
