Aluminum vs Steel Underbody Comparison
Material Build
The UWS box uses a one-piece tub made from 0.058-inch welded aluminum. This metal choice keeps the weight down while maintaining structural integrity. In contrast, the Buyers Products unit is constructed from rugged 14-gauge black steel. Steel is generally thicker and denser than aluminum of similar gauge. This material difference affects how each box resists dents and impacts. You get a lighter aluminum option with UWS or a heavier steel option with Buyers Products. Both finishes are black, but the base metal determines the overall feel and durability profile.
Storage Volume
Size is the most obvious difference between these two units. The UWS tool box measures 77 inches in length, 17 inches in width, and 24 inches in height. It offers a massive storage footprint for long tools and large equipment. The Buyers Products underbody box is significantly smaller, measuring 30 inches long, 18 inches wide, and 18 inches high. This compact size is designed to fit under the truck bed rather than on top. If you need to carry bulky items, the UWS volume is superior. For minimal footprint storage, the Buyers Products size is more appropriate.
Weight Capacity
Weight impacts your truck bed payload and handling. The UWS aluminum box weighs 58 pounds. The Buyers Products steel box weighs 67 pounds. The steel construction adds nearly ten pounds of weight compared to the aluminum unit. This extra weight might matter if your truck has a strict payload limit. However, the steel box is designed for underbody mounting, which distributes weight differently than a roof-mounted aluminum box. You should consider how each weight affects your vehicle's rear suspension and center of gravity when fully loaded.
Lid Strength
The UWS box features a patented RigidCore lid filled with solid foam. This technology prevents lid binding and adds strength to the low-profile design. The Buyers Products box uses a recessed drop door with a stainless steel compression latch. This system provides maximum protection against theft and moisture. The foam-filled lid of the UWS offers unique structural benefits for daily opening and closing. The compression latch on the Buyers Products unit focuses on sealing and security. Both designs aim to keep your tools safe, but they use different mechanical approaches to achieve that goal.
Mounting Style
Installation location defines how you use these boxes. The UWS box is a low-profile unit designed to sit on top of the truck bed. It comes with pre-drilled mounting slots and hardware for easy installation. The Buyers Products box is an underbody unit, designed to hang beneath the truck bed. It requires separate mounting brackets for installation. The underbody style keeps your bed floor clear for cargo. The roof-mounted style keeps your bed floor clear but adds height. Choose the mounting style that best fits your workflow and bed access needs.
Choose the Right Truck Tool Box
You need large, low-profile roof storage
The UWS box measures 77 inches long and 24 inches high. Its low-profile design improves rear visibility. The 0.058-inch aluminum tub keeps the weight at 58 pounds. RigidCore foam filling prevents lid binding. Stainless steel handles offer wide-spread access. This setup suits trucks where bed space and sightlines matter most.
You prefer secure underbody steel storage
The Buyers Products box is 30 inches long and sits under the bed. It uses 14-gauge black steel for rugged durability. The powder coat finish resists corrosion. A continuous hidden hinge and replaceable gasket seal out debris. The stainless steel compression latch adds security. This underbody mount clears your truck bed entirely.
You want versatile mounting options
This steel box supports underbody or flat surface installation. It fits trailers, service trucks, or custom builds. The 18x18x30 inch size offers compact storage. Multiple height and size variations exist for different needs. Mounting brackets are sold separately. This flexibility makes it ideal for specialized work vehicles or trailers.
