How To Install A Tonneau Cover With A Bed Liner

Firstly, let’s begin with selecting the right liner for your truck bed. A good liner should be durable, resilient, and able to withstand the weight of your tonneau cover. Liners come in several types, such as drop-in, spray-on, and bedrug, each with its unique set of advantages.

Before purchasing a liner, it’s crucial to accurately measure the bed of your truck to ensure a perfect fit. Remember, an ill-fitted liner can lead to problems down the line, like water seepage or unwanted movement of the tonneau cover.

Once you’ve selected a liner and measured your truck bed accurately, your next step is to clean the truck bed thoroughly. A clean surface will enhance the adherence of the liner to the truck bed, ensuring a secure fit. It’s best to use a mild detergent and water, and leave the bed to dry completely before applying the liner.

With a clean and dry truck bed ready, you can now install your liner according to the manufacturer’s instructions. Most liners will require some form of adhesive or bolts to secure them to the truck bed. Make sure you follow the instructions meticulously to avoid any potential mishaps.

After the liner is securely installed and given enough time to set, you can proceed to install the tonneau cover. The process involves aligning the cover, clamping it down, and securing it to the bed liner. Always ensure that there is a tight seal between the cover and bed liner to prevent any leakage.

Lastly, remember to regularly inspect your tonneau cover and bed liner for any signs of wear and tear. Regular maintenance will extend their lifespan and keep your truck looking top-notch. Happy driving!

Absolutely! It’s completely feasible to install a tonneau cover on a truck bed that already has a bed liner installed. The process is slightly different but not overly complex.

First, before the installation, ensure your liner is securely attached to the bed of the truck. This is crucial because a loose liner could cause issues with tonneau cover fitment or cause the cover to move around while driving.

Next, you’ll need to make certain that the tonneau cover you choose is compatible with your existing bed liner. Some tonneau covers may not fit correctly with certain types of liners. So, be sure to check the product specifications or consult with the manufacturer if you have any doubts.

The installation process will vary depending on the type of tonneau cover you’re installing. Some require no drilling and can be clamped on, while others may require you to drill into the bed liner. Again, it’s crucial to follow the manufacturer’s instructions to ensure proper installation.

Remember, the key to a successful installation is preparation and patience. Take the time to thoroughly clean the bed liner and let it dry completely before you begin. Then, proceed with care, making sure you align and secure everything correctly.

And there you have it! Installing a tonneau cover on a truck bed with a pre-existing bed liner is a task that’s entirely within your reach. With a little time, patience, and the right tools, you’ll soon be enjoying the many benefits that a tonneau cover can offer.


Many questions arise when it comes to installing a tonneau cover over a bed liner. Here, we aim to address some of the most common queries to help you through the process and ensure a successful installation.

Can I install a tonneau cover myself, or should I get professional help?

While it is entirely possible to install a tonneau cover by yourself, it depends on your level of comfort with DIY projects. The process requires attention to detail and strict adherence to the manufacturer’s instructions.

If you are comfortable with handling tools and have patience, you should be able to manage the installation. However, if you have any doubts about the process, it’s best to seek professional assistance to avoid any potential issues or damage.

Will a tonneau cover fit my truck if it has an aftermarket bed liner?

Yes, a tonneau cover can fit a truck with an aftermarket bed liner. However, it’s essential to check the specifications of the cover and ensure it is compatible with the type of liner already installed on your truck bed.

Also, remember that the bed liner must be securely installed to avoid any issues with the tonneau cover fitment. If you have any doubts, contacting the manufacturer or a professional installer is a good idea.

How do I maintain my tonneau cover and bed liner?

Maintaining your tonneau cover and bed liner is a straightforward process. Regularly inspect both the cover and liner for any signs of wear or damage. Clean them using a mild detergent and water, avoiding any harsh chemicals that could degrade the materials.

If you notice any loose sections or leaks, they should be addressed immediately to prevent further damage. By doing regular check-ups and cleaning, you’re extending the lifespan of both your tonneau cover and bed liner, ensuring your truck remains in top condition.

Final Thoughts

Installing a tonneau cover on a truck bed with a liner may seem like a daunting task, but it’s entirely achievable with the right preparation and patience. Remember, the key to a successful installation lies in the details – from ensuring a clean and dry surface to closely following the manufacturer’s instructions.

The effort you put into the installation process is worth it in the long run. A well-installed tonneau cover provides many benefits, such as shielding your cargo from weather elements, offering additional storage space, and enhancing the aesthetic of your truck.

Meanwhile, the bed liner protects your truck bed from scratches, dents, and rust that could diminish its value. Together, a tonneau cover and bed liner form a formidable layer of protection that will keep your truck in top-notch condition.

So, whether you’re new to truck maintenance or a seasoned pro, don’t shy away from this DIY project. With careful preparation, a keen eye, and a bit of patience, you’ll find that installing a tonneau cover on a liner-equipped truck bed is not only doable but also a rewarding experience. Happy trucking!
