Tool Boxes

Our truck bed tool boxes fit Ford F-150, Super Duty F-250 and F-350, Dodge Ram 1500, Ram 2500 and 3500, Chevy Silverado 1500, Silverado 2500HD and 3500HD, GMC Sierra 1500, Sierra 2500HD and 3500HD, Toyota Tacoma, Toyota Tundra, and Nissan Titan. Whether you need the best crossover tool box for your Ford F-150, an underbody tool box for your Super Duty, or an UnderCover swing case for your Ram 1500, we carry aluminum truck tool boxes, steel truck tool boxes, and poly construction options from WeatherGuard, UWS, Better Built, DeeZee, UnderCover, and Highway Products — all sized for 5-foot, 5.5-foot, 6.5-foot, and 8-foot truck beds.

Crossover, Side Mount, Underbody & Swing Case Tool Boxes for Every Truck

Our crossover truck tool box selection includes single-lid and gull wing tool box designs in bright aluminum, matte black, and gloss black finishes — available in standard depth and deep angled push-button models for F-150, Ram, Silverado, Sierra, and Super Duty. For trucks that need full bed access, side mount truck tool boxes bolt to the bed rail on one side, leaving the center open for lumber, pipes, and oversized cargo. Underbody tool boxes mount beneath the truck bed frame on flatbeds, cab and chassis trucks, and commercial rigs — a popular choice for Super Duty and Ram 3500 work trucks.

For quick-access storage without sacrificing bed space, swing case truck tool boxes from UnderCover mount inside the wheel well and swing out for tool access at the job site. We also carry chest tool boxes for truck beds in 48-inch and 60-inch widths, low profile truck tool boxes that sit below the bed rail line for unobstructed rear visibility, and trailer tongue boxes for enclosed and flatbed trailers. Need a truck tool box that works with a tonneau cover? Many of our crossover and low profile boxes are designed to pair with tri-fold and retractable covers from our Tonneau Covers collection.

Frequently Asked Questions

What is the difference between a crossover and a side mount truck tool box?

A crossover tool box mounts across the full width of the truck bed behind the cab, sitting on top of both bed rails. A side mount tool box bolts to one bed rail only, leaving the opposite side and center of the bed open for tall or oversized cargo like lumber, ladders, and pipe. Crossover boxes offer the most storage volume, while side mount boxes preserve more usable bed space for hauling.

Can you use a truck tool box with a tonneau cover at the same time?

Yes — low profile crossover tool boxes and notched-lid designs are specifically built to sit below or integrate with tri-fold and retractable tonneau covers. The tool box mounts behind the cab and the tonneau cover installs from the tool box forward to the tailgate. Check compatibility with your specific tonneau cover model before purchasing, or contact our team for fitment confirmation.

Is an aluminum or steel truck tool box better for durability?

Aluminum tool boxes are lighter, naturally rust-resistant, and better suited for trucks that need to manage payload capacity — making them the top choice for F-150, Tacoma, and half-ton trucks. Steel tool boxes are heavier and stronger, with higher impact resistance for heavy construction and industrial use on Super Duty, Ram 2500/3500, and Silverado HD work trucks. In Canadian climates with road salt and moisture, aluminum holds up better long-term without requiring paint or coating maintenance.

What is the best truck tool box for contractors and tradesmen?

Contractors and tradesmen typically need a crossover or side mount tool box paired with an underbody box for maximum organized storage. WeatherGuard and UWS are the most popular brands for commercial and trade use because of their heavy-duty latching systems, weatherproof sealing, and reinforced construction. For job site access without climbing into the bed, an UnderCover swing case mounted in the wheel well gives quick reach to frequently used hand tools and power tools.

Is a swing case better than a crossover tool box for daily use?

A swing case is better for truck owners who need quick access to a smaller set of tools without losing any bed space — it mounts inside the wheel well and swings out at the tailgate. A crossover tool box is better for truck owners who carry a large volume of tools, hardware, and equipment that needs to be locked and organized in one place. Many contractors run both — a crossover for bulk storage and a swing case for frequently used items.

Are truck tool boxes waterproof or do they leak in rain and snow?

Most quality truck tool boxes from WeatherGuard, UWS, and Better Built use foam gasket seals and overlapping lid designs that are weather-resistant but not fully submersible waterproof. They will keep rain, snow, and road splash out during normal driving and parking conditions. For Canadian winters with heavy snow buildup, a tool box with a raised lid seal and drainage channels will prevent standing water from pooling and seeping into the box over time.
