MX4 is one of the most stunning products from BAKFlip’s range of hard folding truck bed covers. It is worth every penny that you spend as it comes packed with exciting features. The tri-folding design ensures that you get complete access to the entire truck bed.

This cover works well for carrying both small and large items. It is one of those covers that strikes a balance between protection and convenience.

The product is very durable and offers protection against water, UV rays, and dents. Additionally, you can install it easily, without any third-party mounting brackets or drills. 

Before we discuss the different features in this BAKFlip MX4 review, let’s run through the pros and cons of the product.


When it comes to design, the MX4 is a pretty straightforward product. It features a three-fold design, which means that the cover has three segments that fold towards the inside of the cab.

Hard folding covers are pretty easy to handle. The folding design makes it all the more convenient to deal with the cover whenever you wish to access the truck bed.

Moreover, rolling covers can either remain open or closed. However, the tri-folding cover design of the MX4 makes it possible to open just one or two panels at a time, keeping the rest of the truck bed covered.

Each segment of this cover is made with aluminum paneling for increased rigidity. The aluminum offers better, more sturdy protection in comparison to traditional softcovers.

The MX4 also features an injection-molded latch buckle system. It helps you conveniently control the folding mechanism. The integrated buckle system on each of the folds is ideal for securing the cover without using any straps or bungees.

The cover also features a safety strap with prop rods that keep it in place when fully folded. It ensures unobstructed access to the bed while allowing you complete visibility over the third brake light.

You can fold the cover from either the driver side or the passenger side with the help of pull latches hidden under the covers.

Build Quality and Durability

The aircraft-grade aluminum paneling and frames ensure a high-quality product. They are advantageous for two reasons. Not only does aluminum ensures that the tonneau cover remains sturdy, but it also makes it very lightweight.

The perimeter seals on the cover are made with heavy-duty materials so that they remain solid. Moreover, this cover also comes with additional hardware and accessories of the best quality.

The cover panels can hold up to 400 lbs of weight, as long as it gets distributed evenly.

The best part, perhaps, is that the cover is completely water repellent. It does away with any moisture on its surface and doesn’t let water leak into the bed.

In addition, it is also UV-ray resistant and dent resistant. The finish works wonderfully against various scratches, fingerprints, etc.


Installing the MX4 is a pretty quick and straightforward task. You can get the job done in under 15 minutes, thanks to the clamp-on installation design.

Unlike the complicated rolling covers, the simple fold design makes the task pretty convenient. You will not need any mounting brackets or drills to install this cover. However, it may not be a one-person job as it requires lifting the bed cover over the truck.

The MX4 comes with a dual-action tailgate seal. It implies that you can close the tailgate without worrying if the bed cover is open or closed.

Upon installation, the cover sits atop the bed rails and leaves a little space at the edges on most trucks. You can fasten the supporting rails using clamps on either side of the truck to ensure that the cargo doesn’t move around when the truck does.

Security and Protection

Since this truck bed cover is hard folding instead of rolling, it is a pretty secure option. If you close it completely, no one will be able to access the bed from outside. The MX4 protects the truck bed with a locked tailgate.

Unfortunately, the smart locking mechanism enables anyone to access the cover latch even if the tailgate is up.

The bed cover is integrated with dual drain tubes to offer protection against rain. The tubes remove the water from the cover and direct it outside the truck bed. Additionally, the sealed perimeter prevents rainwater from entering.

The Final Verdict

This BAKFlip MX4 review shows us that it is one of the most versatile tonneau covers available. It is worth every penny you spend, owing to its stunning features.

While the security of the cover could use some improvement, the build quality is truly commendable. Moreover, there is a 30-day guarantee that entitles you to a refund if you are not happy with the product.

If you’re looking for an affordable truck bed tonneau cover that offers simplicity, protection, and flexibility, this product will serve you well.

We hope this BAKFlip MX4 review helps you getter a more detailed look into the product and make an informed decision.
