Find Your Full-Size Truck Tool Box Here

Driving a full-size pickup gives you serious capability, but all that power and payload capacity only go so far without secure, organized storage. That’s where a full-size truck tool box comes into play. More than just an accessory, it’s a smart, functional upgrade that protects your gear, keeps your bed organized, and helps you get the most out of your truck.

Whether you're a contractor hauling tools to your jobsite, an outdoorsman organizing hunting and fishing gear, or someone who simply wants secure, weather-resistant storage for everyday use, the right tool box transforms your bed into a smarter, safer workspace.

And the best part? With a full-size truck, you’ve got more options to choose from. Larger beds mean more flexibility,  and UWS delivers with a wide lineup of tool boxes built specifically for full-size pickups. From crossover boxes that maximize bed rail space, to chests and side boxes that work seamlessly with tonneau covers and racks, we make it easy to find the setup that fits your truck and your life. Every UWS tool box is made right here in the USA, engineered for strength, sealed for protection, and backed by a legacy of hard-working reliability.

A crossover truck tool box mounts directly to the rails of your truck bed, spanning the full width of the bed behind the cab. It’s suspended above the floor, giving you secure storage without taking up valuable bed space. That means you can haul longer items like lumber or ladders underneath the box, while keeping tools and gear locked up and protected above.

Crossover tool boxes are one of the most popular storage solutions for full-size pickups because they strike the perfect balance between accessibility, capacity, and versatility. You can open them up from either side of the truck and can still use your entire bed floor for cargo.

UWS utility chests are a versatile, all-purpose storage solution designed to sit securely inside the bed of your full-size pickup. Mounted against the cab wall, they offer spacious, top-opening storage without taking up rail space, making them ideal for truck owners who use tonneau covers or ladder racks. Unlike other truck tool boxes, utility chests deliver a large, uninterrupted interior, giving you flexible, reliable storage that doesn’t get in the way.

Every UWS utility chest features extra-thick aluminum construction for superior strength and dent resistance. The RigidCore™ foam-filled lid adds structural integrity while providing smooth, stable operation, even in tough environments. With corrosion-resistant stainless steel latches, a self-opening lid with gas struts, and a weather-resistant seal to keep out moisture and dust, UWS utility chests are built to protect your gear — and keep your truck bed organized and ready for whatever comes next.

UWS side-mount truck tool boxes are expertly crafted to maximize your storage capacity without taking up valuable truck bed floor space. Mounted securely along the inside bed rails of your full-size truck, these boxes offer quick, convenient access to your tools and gear whenever you need them.

Built from extra-thick, heavy-gauge aluminum and reinforced with strong, durable welds, every UWS side-mount truck tool box is designed to withstand the demands of daily work and harsh weather conditions. Our durable MicroSeal™ gasket seals out rain, dust, and debris to keep your gear protected, while corrosion-resistant stainless steel hardware ensures long-lasting reliability. Whether you’re tackling a tough jobsite, heading out on the trail, or simply hauling gear from your local hardware store, UWS side-mount tool boxes provide secure, dependable storage that keeps your truck organized and ready for anything.

Choosing the right tool box or combination of boxes for your full-size truck starts with understanding how you use your truck on a daily basis. Are you hauling tools to the jobsite, transporting outdoor gear, or just looking to keep everyday items organized and secure? Your specific needs will help determine not only the style of box that works best but also how many boxes your setup should include.

Start by thinking through how you use your truck on a day to day basis. Think about your typical workload and what you carry in your truck regulary. A single crossover box is a great all-purpose option and often enough for truck owners who need basic, secure storage with easy access from either side of the bed. If you carry a variety of tools or gear types, adding a pair of side-mount boxes can help organize smaller items without giving up bed floor space. For full coverage, consider combining a crossover with a utility chest or side boxes to create a multi-box system tailored to your workflow.

Bed size also plays a major role. Measure your truck bed to ensure proper fit and compatibility. Full-size trucks generally offer more space, which opens up options for extra-wide or deep boxes that maximize storage capacity. Just be sure to account for how much bed space you want to keep open for hauling larger items.

Consider any existing accessories that could affect box placement or fit. Tonneau covers, headache racks, ladder racks, and even gooseneck hitches can impact your box choice. For example, if your truck is equipped with a tonneau cover, a low-profile utility box may be a better fit than a crossover box. If you’re using a ladder rack, side-mount boxes might provide better access without interference.

Think long term. Your storage needs might evolve as your work or hobbies change. Choosing a modular setup with room to grow can save you time and effort down the road. UWS tool boxes are built to work together, allowing you to expand your system as needed without starting from scratch.

UWS extra-wide tool boxes are designed for truck owners who need more storage without compromising accessibility or bed space. By extending further from front to back, these boxes provide significantly more interior volume than standard-width models. The extra width makes it easier to keep everything organized in one central location, especially for professionals who rely on a wide range of tools every day.

But it’s not just about size. Each UWS extra-wide tool box is built with the same rugged features that define UWS, including extra-thick aluminum construction, our patented RigidCore™ lid for added strength, and stainless steel hardware for long-lasting performance. Despite the added capacity, these boxes are designed to maintain a clean, professional look and a snug fit in the bed of your full-size truck. For those who need more storage without adding multiple boxes, Extra-Wide is the smart, efficient solution.

UWS deep crossover tool boxes are designed for truck owners who require additional storage capacity without compromising accessibility or bed space. These boxes feature a deeper tub than standard models, providing more room to store larger tools, equipment, and gear. UWS Deep Crossover Tool Boxes are also constructed from extra-thick auminum, ensuring they can withstand the challenges of daily use and harsh weather conditions. The patented RigidCore™ foam-filled lid enhances strength and prevents warping, while the MicroSeal gasket keeps out moisture, dust, and debris. Additionally, the self-opening lid provides easy access, and the built-in tool trays and screwdriver holders help keep your tools organized and within easy reach. With these features, UWS deep crossover tool boxes offer a reliable and efficient storage solution for your truck.
