Bradford Aluminum 4-Box Pickup Flatbed | Multiple Bed Sizes

Available Flatbed Sizes & Vehicle Footprints

Flatbeds must be carefully sized based on single vs. dual rear wheel chassis capacity to ensure perfect wheel-well flare clearance and turning radii. Note: Standard wheel wells are intended for stock tires. If you are running an oversized tire/wheel setup, call our staff to spec the 40" larger wheel well options.

Below is the master sizing chart to match the Aluminum 4-Box Utility flatbed to your specific chassis runner width and CTA:

The Structural Backbone: Built on a Steel Subframe

To ensure you never compromise on towing capacity or frame rigidity, all Bradford Built Aluminum work bodies are built with a heavy-duty steel subframe to give you superior strength exactly where you need it. The steel frame and hitch components are fully welded and powder-coated to resist corrosion, perfectly supporting the lightweight, rust-proof aluminum deck and skirting.

Comprehensive Standard Features

• Integrated Storage: Comes standard with 4 flush-mounted, weather-sealed underbody insert toolboxes built directly into the deep aluminum skirting.
• Elite Towing Setup: Arrives factory-equipped with a steel 30,000 lb. rated Gooseneck Hitch and a 24,000 lb. Tow / 1,800 lb. tongue weight rated Class V receiver hitch. (Note: Drop or pintle hitches may alter specific capacities).
• Formed Headache Rack: A signature Bradford Built look featuring a bolt-on design for a clean fitment to your truck cab. It comes standard with stop, reverse, and side marker lights.
• Enhanced Body Styling: Extended deep skirting completely shields the truck frame, providing a premium show-truck look.
• Electrical & Accessories: Standard fuel hookup routing, fully sealed LED lighting, and an integrated 7-pole trailer plug-in box to prevent electrical shorts in wet conditions.
