Construction & Design

The Fabtech 4-inch Crossmember Lift System is built with precision and durability in mind. The main crossmembers are constructed from 1/4-inch thick steel, providing exceptional strength to handle rugged terrain and heavy loads. The high arched design of the lower control arm crossmembers not only enhances ground clearance but also preserves proper suspension geometry, ensuring predictable handling and steering response.

The ductile iron steering knuckles are engineered to retain the factory track width, which helps maintain the vehicle's original handling characteristics and prevents tire rubbing. The system's components are designed for easy installation, with bolt-on assembly that requires minimal modifications. The rear lift is achieved with a straightforward block and U-bolt setup, making it accessible for DIY enthusiasts and professional installers alike.
