Construction & Design

The Fabtech 4Link System is built with precision and quality in mind. The heavy-duty steel links are mandrel-bent and TIG-welded to ensure strength and consistency. The race-style Uniballs are sealed to prevent dirt and debris ingress, extending service life and maintaining smooth operation. The steel brackets are laser-cut and formed to exact specifications, ensuring a perfect fit without modifications.

This system's design emphasizes ease of installation, with all components engineered for bolt-on compatibility. The use of thick steel brackets and high-quality materials ensures long-lasting performance under heavy loads and off-road conditions. The inclusion of sway bar drops and trac bar brackets helps maintain factory handling characteristics and proper alignment, even with the increased ride height.
