Universal mounting brackets for underbody boxes

These black structural steel brackets mount any compatible underbody or undertruck box with a universal hole pattern. The corrosion-resistant finish protects against road salt and moisture in daily driving conditions. Each package includes two brackets and all required mounting hardware for a complete installation.

Simple bolt-on installation with included hardware

The brackets use a universal hole pattern that aligns with standard box mounting points, reducing the need for drilling new holes. Corrosion resistance is maintained only when the supplied hardware is used, as mismatched fasteners can create galvanic corrosion at the contact surfaces. Tightening bolts to the box manufacturer's torque specification prevents loosening from vibration over time.

Verify box hole pattern

Confirm that your underbody or undertruck box uses the universal hole pattern these brackets are designed for, as proprietary patterns will not align. Ensure the vehicle mounting surface is flat and structurally sound to support the box weight without flexing. Check that the 18 inch dimension suits the box width and the available frame clearance on your specific vehicle.
