Product Description
Bradford Built | Aluminum 4-Box Utility | 4 Integrated Toolboxes, Steel Subframe, & 30% Weight Savings
The Bradford Built Aluminum 4-Box Utility delivers the ultimate combination of utility, style, and efficiency. By upgrading to lightweight high-strength structural aluminum, you gain a massive 30% weight savings over the steel version, improving your half-ton or heavy-duty truck's payload capacity and fuel economy. It features a 2" fender skirt and a wide deck, giving you a highly refined, 'finished' show-truck look. By shielding the truck frame with deep skirting and integrating four flush-mounted, weather-sealed underbody toolboxes, this bed provides immense storage for tools and chains while standing up to the heaviest Magic Valley workloads.
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.
