Construction & Design

The Fabtech Sport II suspension components are built with durability and performance in mind. The coil springs are made from high-tensile steel, providing consistent lift height and resistance to sag over time. The track bar brackets and support components are fabricated from heavy-duty steel and feature precise welds for maximum strength and longevity.

The system's design ensures proper alignment and handling characteristics are maintained, even after lifting. The adjustable alignment cams allow for fine-tuning of caster angles, which is critical for steering stability and tire wear. All brackets and mounts are engineered to fit perfectly with the factory chassis and suspension geometry, ensuring a seamless upgrade that maintains factory safety and reliability standards.
