How to Install a Top Lit Toolbox on Your UTE?

Gather the necessary tools and materials

You will need a variety of tools to get the job done. First, you will need the actual top lid toolbox. You can purchase this item at some of the many shops providing vehicle accessories and upgrades. Find one that matches your requirements in terms of size, material, and features.

Then, you will need a mounting kit. Most toolboxes come with a mounting kit that includes brackets, bolts, washers, and nuts. Ensure that you have the appropriate mounting kit for your toolbox, such as a power drill, drill bits, screwdrivers, measuring tape, marker or pencil, level, socket set, and a ratchet.

Choose the installation location

Think about where you want to install the toolbox on your UTE. Consider several factors, such as accessibility, convenience, and the impact on the vehicle’s balance. Most UTEs have a bed area at the rear, which is the perfect place for an item like this.

Measure and mark the mounting points

Place the toolbox in the desired location and use a measuring tape to mark the mounting points on your UTE’s bed rails or sidewalls. Ensure that the marks are symmetrical and aligned correctly. If you miss just an inch, you’ll not be able to mount the box properly. This is one of the most important things even though many people fail to take it as seriously as possible.

Pre-drill holes

Using a power drill with an appropriate drill bit, pre-drill holes at the marked locations on the UTE’s bed rails or sidewalls. The hole size should match the diameter of the bolts provided with the mounting kit. Pre-drilling will make it easier to attach the toolbox later.

Install the mounting brackets

Attach the mounting brackets to the toolbox. The brackets should align with the pre-drilled holes in the UTE’s bed rails or sidewalls. Use the provided bolts, washers, and nuts to secure the brackets to the toolbox and the UTE. Tighten them securely using a socket set and ratchet.

Level the toolbox

Use a level to ensure that the toolbox is properly aligned and leveled. Make any necessary adjustments to the mounting brackets to achieve a balanced installation. Although during driving the items inside will surely not stay perfectly flat, it’s important not to cause a reason for concern in front. Additionally, an uneven box during installation will mean a higher chance for issues later.

Secure the toolbox

Once the toolbox is level, double-check that all bolts, washers, and nuts are tightened securely. This will ensure that the toolbox is firmly attached to your UTE. If some of them are not perfectly attached, it may cause your entire box to be loose and eventually cause serious problems while driving. Double check everything, as it is normal to miss some of the screws and think you screwed them, while they are only placed.

Test the installation

Give the toolbox a gentle shake and verify that it is stable and doesn’t move excessively. This will confirm that it is securely installed. It may sound silly, but this is the best way to ensure you’ve done a great job.

Weatherproofing and customization

If your toolbox didn’t come with weatherproofing features, you can add weather stripping or silicone sealant around the edges of the toolbox to prevent water or dust from entering. You can also customize the toolbox by adding additional accessories like locks, dividers, or foam inserts.


It is essential to consult the installation manual provided with your specific toolbox, as the installation process may vary slightly depending on the brand and model. Some boxes may be too complex, so it may be best to let professionals handle this for you.

Those who are sure that this is nothing special, and they can handle the job themselves, must follow the manual precisely. If they do, and handle the task perfectly, they’ll be able to use the top lid box for many years.
