How Do You Make a Truck Bed Cap?

A truck bed cap is an ideal way to customize and protect the bed of your pickup truck. While it may seem like a daunting job, making your own truck bed cap is relatively easy and cost effective. With the right tools and supplies, you can make a custom truck cap that will fit the contours of your pickup and look great for years to come.

The first step in making a custom truck bed cap is to measure the length, width, and height of your truck bed. This will help you determine how much material you need for your cap. You should also measure the tailgate opening so you know how much material will be needed for that area.

Next, you’ll need to decide what type of material you want to use for your cap. Popular choices include aluminum, fiberglass, or plastic. Each material has its own benefits and drawbacks so it’s important to research which one is best suited for your needs.

Once you have chosen the material, it’s time to cut out the pieces that will make up the frame of your cap. You can use either a jigsaw or a router with a template guide to make precise cuts. Make sure that each piece fits together snugly before moving onto the next step.

The next step is to attach the frame pieces together with screws or rivets depending on what type of material you are using. This part can be tricky so if you are unsure about how to do this properly, it may be best to consult an experienced person before continuing.

After attaching the frame pieces together, it’s time to cover them with sheet metal or other sheeting material of your choice. Once this is done, you will need to drill holes in order to attach hinges if desired as well as other hardware such as locks or handles.


Making a custom truck bed cap requires some planning and preparation but ultimately can be done by anyone who has some basic knowledge of fabrication tools and techniques. With patience and attention paid to detail throughout each step of the process, anyone can create their own durable and stylish truck bed cap that fits their specific vehicle and needs perfectly.
