The Benefits of an Undercover Swing Case Storage Box

An Undercover swing case truck bed toolbox is one of those things you needed, but you never knew you needed.

To learn more about how the swing case can change your life, check the section down below:


One of the main benefits this little toolbox offers is convenience.

Having that little toolbox swing out as you unlock the tailgate is super convenient.

You can easily reach your tools, and if you’re working on your truck, you can leave your tools on the tray and then grab them as you’re working.

Keeps Your Tools Organized

A swing case is super convenient when it comes to organization.

They are designed to keep your tools organized even when going over bumps.

If you carry a few shackles, snatch straps, and so on, a swing case would make it easier for you to store them.

In addition to that, if your swing case has a drink holder, you can work on any project you want and still have a drink next to you.

Take It Anywhere You Want

Yeah, keeping your tools organized is pretty cool, but what if you ever want to take off the swing case?

Well, you can do so with the undercover flex replacement parts. Simply lift it up, and then you should be able to pull it out.


If you don’t carry much stuff around daily, you’ve probably thought about getting a swing case or a tonneau cover.

Both of these aftermarket products are quite popular among truck owners. But the latter can be expensive and difficult to install.

The former is pretty easy to install and cheaper. This is quite attractive for drivers, especially if you just want to carry a couple of tools.

Factors to Consider When Buying an Undercover Swing Case Truck Bed Toolbox

Below we’ve broken down the various factors you must consider before getting a swing case from Undercover. With that being said, let’s take a look.


If you don’t have a tonneau cover, you should get a swing case that is closely sealed so water won’t get inside. Your tools could get corroded over time as more and more water gets inside.

Moreover, if you have anything that could easily be ruined by water, you certainly don’t want to risk it. So, make sure the model is watertight.

180 Degrees

Another essential factor you should consider is that your swing case should swing out at least 180 degrees.

This way, you’ll have a much easier time reaching into it.

You could either reach the swing case from the tailgate without having to unlock it or from the side.

Either way, this is a must for any swing case.

Bed Space

As you might know, the swing case takes up a little bit of a truck bed. So, you’ll have to sacrifice some of it.

The main point to take from this is that you should get a compatible model with the tonneau cover.

It should be at least 3 inches away from the bed cover. Otherwise, you’ll have a hard time installing it.

Maximum Capacity

Upon reading undercover swing case truck bed toolbox reviews, we’ve seen consumers point out is how weak their swing cases are.

Putting more than 15-20 pounds will drop the unit.

This is super-inconvenient and defeats the whole idea of getting a swing case in the first place.

To get around that, check the maximum capacity. In general, any decent swing case should easily be able to handle more than 70 pounds.

Anything below that number is just asking for trouble.

Ease Of Use

Generally speaking, swing cases are super easy to install since they have undercover flex replacement clips. You can also check the undercover swing case reviews. However, you only need a wrench and a couple of minutes to install one.

You don’t even need previous experience to mount one of these.

Moreover, any decent swing case should allow the user to easily pull it out.

You shouldn’t have to use tools to mount it. Lifting it up should be more than enough to take it off.


Any long-lasting swing case should be made of ABS plastic. This is an excellent material for swing cases.

Keep in mind that they carry a lot of weight daily, and they’re likely to get damaged at some point.

Hammers and any other bulky tools are responsible for destroying swing cases. So, watch out for that when getting one.

Sliding Tool Tray

Another feature your swing case should have is the ability to remove the trays.

Most swing cases come with two trays. But only one can be removed. The other one is simply attached to the swing case itself.

So, taking them off comes in handy if you want to keep your tools organized but still take the tray elsewhere.

Some models also include a drink holder, which is pretty useful if you’re working on a project and need to take a drink.

Lightweight Design

And finally, your swing case should be lightweight.

The reason is that if you want to carry the toolbox around, you don’t want it to be too heavy.

Think about how heavy your tools are, plus the extra weight added by the swing case itself.

How to Install an Undercover Swing Case Truck Bed Toolbox

One of the most common ways to store tools is to use a swing case. To install one of these, refer to the section below:

1. What You Will Need

For this job, get all these tools:

  • A drill—to install the mounting bracket, you’ll have to drill a couple of holes.
  • A wrench—after installing the mounting bracket, make sure to tighten all the bolts with a wrench
  • Pliers—to remove the rubber caps from the bracket, you might need a set of pliers

2. Set Up The Brackets

If you take a closer look at the small bracket, you’ll notice that it has two little rubber caps. You need to remove those.

To do this, grab your set of pliers and pull them out. After that, take the large one and put it on top of the rubber.

Next up, put the bolts on and then tighten them using the wrench.

3. Undercover swing case truck bed toolbox installation

Depending on your truck, you might have a couple of holes for the swing case to go in.

However, if that’s not the case, you’ll have to drill a couple of holes and then line it up.

To do this, lift the mounting bracket and hold it against the truck.

After that, drill through it. Do not go all the way, and don’t overtighten them.

If you over-tighten them, you’ll strip the bolts. So, be careful.

Now keep doing this for all the bolts. Next up, do the same thing for the horizontal side.

Make sure to perfectly line it up before drilling. After that, grab the wrench and tighten all the bolts you just drilled.

Finally, grab the swing case and put it on the mounting bracket.

And you’re now done with the installation process. This is an effortless job and takes 10 minutes at most.
