Construction & Design

The Fabtech 5-inch Rear Leaf Spring Block Kit features a robust flat block design made from high-quality steel, ensuring strength and durability under demanding conditions. The blocks are precision-machined to exact specifications for a perfect fit, reducing the risk of movement or shifting during operation. The flat profile maintains a low profile, preserving ride comfort and handling characteristics.

All components are finished with a protective coating to resist corrosion and rust, making this kit suitable for off-road environments and harsh weather conditions. The straightforward design allows for quick installation, enabling you to upgrade your suspension without extensive modifications or specialized tools.

Performance & Sound

By elevating the rear of your truck, this lift kit not only enhances the vehicle's appearance but also improves ground clearance for off-road adventures. The increased height can help prevent bottoming out on rough terrain and support better approach and departure angles. While this kit does not directly increase horsepower or torque, it provides a stable platform for additional modifications if desired.

Since the kit consists of solid steel blocks, it does not significantly alter the vehicle's noise profile or driving dynamics. You can expect a more commanding stance and improved load support, making your truck better suited for towing, hauling, or off-road use.

Installation & Fitment

The Fabtech Rear Leaf Spring Block Kit is designed for a straightforward bolt-on installation. It uses the existing leaf spring mounting points and requires no cutting, drilling, or welding. Basic mechanical skills and standard hand tools are sufficient to complete the upgrade in a few hours. Proper alignment and safety checks are recommended after installation to ensure optimal handling and performance.

• Compatible with 2011–2025 Ford F-150, F-250, and F-350 trucks.
