Along the way, we’ll offer tips and tricks to make the installation smooth and ensure a secure fit. We’ll also discuss maintenance tips to keep your tool box in top condition. Let’s get started!

Installing a truck tool box is relatively straightforward and requires only a few basic tools that most truck owners already have in their garage. With a good tool box design, like the ones from UWS, you’ll find that the tool box installation process is intuitive. In this guide, we’ll focus on a crossover truck tool box, which is one of the most popular styles for pickups.

Before you begin, be sure to confirm that the tool box you’ve chosen will fit your truck. We'll go over how to do that next!

Before purchasing a tool box, the first thing you need to do is ensure that it will fit properly in your truck bed. Most tool boxes are designed to fit specific bed sizes, so take accurate measurements. To help you out, we’ve created a guide on how to measure your truck bed for a tool box.

In addition to measuring your truck bed, check your vehicle’s capacity. Avoid obstructing important components such as brake lines or fuel lines. It’s always a good idea to consult your truck’s manual to identify any areas to avoid during installation. Safety is key, so take your time and double-check all clearances.

Once you’ve confirmed that your tool box will fit, it’s time to gather the materials. Most UWS tool boxes come with everything you need to install the box, including:

• Tool box J-hooks
• Washers
• Nuts
• Protective adhesive rail pads
• Instruction manual

• Ratchet
• Socket set
• Measuring tape
• Utility knife (for trimming adhesive pads, if necessary)

Extra hands? Installing a tool box is generally a one-person job. However, having a friend or family member assist can make it easier, especially when it comes to positioning and securing the box.

Now that you’re all set with your tools and your tool box, it’s time to get it installed! Follow these easy steps and you'll have your truck tool box installed in no time. 

The first step is to place the tool box in your truck bed. Start by sliding the box into the bed and positioning it as far up against the bulkhead (the wall behind your truck cab) as possible. This will give you maximum bed space and ensure your box doesn’t obstruct the rear window or cab.

Once you’ve positioned the tool box, check the side-to-side alignment. You want to make sure the box is centered in your truck bed, with equal space on both sides. Using a tape measure, make sure the tool box is centered in the truck bed.

Also, open and close the lid several times to ensure it operates smoothly and doesn’t hit the truck cab or any accessories like a headache rack. If there’s any obstruction, reposition the box accordingly. Make sure that there is clearance between the open lid, top and back of the cab.

Before securing the tool box, install the protective adhesive rail pads that come with your UWS tool box. These pads protect your truck’s paint job from scratches and wear caused by the tool box shifting during travel. Simply peel the backing off the pads and stick them onto the underside of the tool box’s contact points. Trim with a utility knife if necessary.

Now that the box is aligned and protected, it’s time to secure it. UWS tool boxes include J-hooks, which make them super easy to install. Here’s how they work:

• Place a J-hook under the lip of the bed rail and insert the threaded end up through the slot. Only use one hole and J-hook assembly on each side
• Attach with a washer and nut. Snug the hardware, but do not fully tighten
• Repeat on the other side of the vehicle
• Re-measure to ensure the tool box is centered and allows lid clearance when open
• Fully tighten all hardware

The J-hooks will keep the box in place and ensure it’s secure. This method eliminates the need to drill into your truck which can be a major pain.

After securing the box, check the strikers and locks. If they’re not perfectly aligned, make any necessary adjustments to ensure they work smoothly. It’s also a good idea to lubricate the strikers and locks with a silicone-based lubricant to keep them functioning, especially if you travel frequently through rain, dust or grime. That's it! Congratulations on the installation of your new crossover truck tool box. 

 
Installing a truck tool box can present several challenges, especially for first-time installers. Here are some of the most common installation problems that people have when installing a truck tool box. 

One of the most frequent challenges when installing a truck tool box is ensuring a proper fit. Tool boxes come in various sizes and styles, and not all of them fit every truck bed. If you don’t measure your truck bed correctly before purchasing, you might find that the tool box doesn’t sit properly in the bed or obstructs important components like the rear window or cab.

Solution: Always measure your truck bed before purchasing a tool box. Refer to the manufacturer’s fitment guide and double-check the dimensions of the box against your truck’s specifications. If you’ve already purchased the wrong size, don’t try to force the installation. Return or exchange it for one that is correctly sized. Custom-fit tool boxes designed for specific truck models can also eliminate this problem altogether.

Once the tool box is installed, you might notice that the strikers (the metal parts that latch when you close the box) or locks don’t align properly. This can prevent the box from closing securely, leaving your tools vulnerable to theft or exposure to the elements.

Solution: Check the alignment of the tool box before fully securing it. Open and close the lid several times to ensure it operates smoothly. If the strikers or locks are misaligned, loosen the bolts slightly and adjust the box’s position. Additionally, you can lubricate the strikers and locks with silicone-based lubricant to ensure smooth operation.

Even after a successful installation, some tool boxes may move or shift slightly during travel, especially on rough terrain. This can lead to damage to both the tool box and the truck bed, as well as an annoying rattling sound.

Solution: Periodically check the hardware (J-hooks, clamps, or bolts) securing the tool box to ensure that nothing has loosened over time. Tighten as necessary, but avoid overtightening, which can damage the truck’s side rails.

If your truck is equipped with a headache rack, the tool box installation could interfere with it, making the installation more complicated.

Solution: Many headache racks are designed to accommodate tool boxes, but if there’s interference, you may need to adjust the positioning of the tool box. Move the box slightly forward or backward to create the space needed for both the headache rack and the tool box to coexist without obstruction. Double-check that moving the tool box doesn’t obstruct other parts of the truck or impact visibility from the rear window.

Once your tool box is installed, the job isn’t quite done. Proper maintenance will keep your tool box looking good and working properly for years to come. Here are some key maintenance tips.

1. Regularly inspect the hardware: Over time, vibrations from the road can loosen the nuts and bolts securing your tool box. Make it a habit to inspect them every few months and tighten them as needed.
2. Clean the exterior: Use a mild automotive detergent to clean the outside of your tool box. Avoid using dish detergent, abrasive cleaners, abrasive pads, wire brushes, and other products that may damage the finish.
3. Lubricate the locks: Apply silicone-based lubricant to the locks and strikers every few months to prevent them from rusting or sticking.
4. Check the weather seals: The weatherproof seal on the tool box is crucial for keeping water and dirt out. Inspect the seals regularly to ensure they’re intact and replace them if necessary.

By following these maintenance tips, you’ll extend the life of your tool box and keep your tools safe and secure for years to come.

Installing a truck tool box is a smart way to protect your equipment and make the most of your truck’s storage capacity. Whether you're a contractor hauling tools or an adventurer heading off-road, a well-installed tool box, like a UWS Crossover Tool Box, keeps your tools organized, secure, and ready at a moment’s notice.

UWS tool boxes stand out from the competition thanks to their extra-thick aluminum construction, weather-resistant RigidCore™ lids, and easy installation process. Their J-hook mounting system eliminates the need for drilling, while their protective rail pads help preserve your truck’s finish. With a UWS tool box, you don’t just get a rugged, durable and secure place for your tools. You get a tool box you can be proud to pass down to your children and grandchildren.

Congratulations on a job well done! Your truck is now more organized, functional, and ready for whatever life throws your way.

To determine the right size crossover tool box for your truck, you need to consider several factors, such as the type of truck you have, the bed size, and your specific storage needs. The easiest way to determine what tool box will fit truck is by using our tool box fitment guide.

No, truck tool boxes are not one-size-fits-all. Truck beds vary in width, length, and depth depending on whether the truck is a compact, mid-size, or full-size model. Toolboxes come in various sizes to match these different bed dimensions, so a toolbox that fits one truck may not necessarily fit another.

In many cases, no drilling is required. UWS truck toolboxes come with J-hooks that attach to the truck bed rails. However, some toolboxes may require drilling, especially if you prefer a more permanent installation or if your truck bed is not designed for easy mounting.
