Secure and durable, it’s the kind of cover that works hard and won’t let you down. Simple as that, it looks good, it’s built to last, and it’s got your truck bed covered.

However, it is more prone to dents and scratches because of its aluminum exterior and matte black paint. It’s BAK’s all-time best-seller because of its looks and robustness.

My Personal Experience with the BAKFlip MX4 Tonneau Cover for a 2019 Chevy Silverado:

Things I like about BAKFlip MX4:

  • Excellent Build Quality: Right out of the box, the cover felt robust and well-constructed, promising durability.
  • Simple Installation: I was able to install the cover myself with basic tools and no fuss. It was reassuring to know that I didn’t need to be a pro to get it securely attached and looking great.
  • Aesthetic Appeal: Not only did it enhance the look of my truck, but it also added a practical edge.
  • Ease of Use The design facilitates easy folding for full bed access, and re-securing it is just as effortless. The cover’s functionality in everyday use is admirable.
  • Security Boost: The cover provides a solid layer of security for my belongings, significantly reducing worries about theft during travels.
  • Installation: It was mostly straightforward, although having an extra pair of hands made it easier.

Areas Where It can be Improved:

  • Delivery Issues: My cover arrived with a dent on the frame and a missing clamp, like the closing strap. So I had to call customer service and get a replacement.
  • Water Resistance Not Perfect: I noticed some water leaking near the tailgate area after installation.
  • Fitment Hiccups: Components like the water tubes didn’t fit perfectly and required additional adjustments.
  • Panel Top got some Scratches: I’ve got to admit, I wasn’t the gentlest with maintenance, and as a result, the top did get some scratches.

Theft Protection

BAKFlip MX4 incorporates several features designed to enhance the security of your truck bed, although it’s important to note that no tonneau cover can provide 100% theft-proof protection. The MX4 offers practical measures that act as deterrents and add an extra layer of security.

The fully extended cover, paired with a locking tailgate, conceals your truck bed’s contents, keeping potential thieves in the dark about what’s inside. This out-of-sight approach decreases the likelihood of drawing unwanted attention.

MX4 features recessed cable pulls at each end of the back rail, used to release the panels. These pulls are only accessible with the tailgate lowered. So, with a locked tailgate, the MX4 provides an additional hurdle for would-be thieves.

Moreover, the MX4 allows you to close the tailgate without opening the panel, offering easy access to items at the bed’s end when needed.

While the BAKFlip MX4 significantly boosts your truck bed’s security, it’s vital to take additional precautions. Keep valuables out of sight and choose secure parking spots whenever possible.

Ease of Access and Impact on Driving

Opening and closing the BAKFlip MX4 tonneau cover is a breeze, providing easy access to your truck bed.

Simply locate the recessed cable pulls at the back rail and give them a gentle tug. This releases the latches, allowing you to fold the panels towards the cab effortlessly. It ensures that you have full access to your truck bed whenever you need it.

Additionally, segmented panels can be fixed in position with the help of props, making it effortless to load and unload your cargo.

The BAKFlip MX4’s low-profile design not only enhances the truck’s aesthetic but also improves driving experience by reducing wind resistance.

This leads to quieter rides, ensuring a more peaceful driving environment. Additionally, its aerodynamic structure contributes to overall driving comfort, making journeys smoother and more enjoyable.

The BAKFlip MX4 is known for its sturdiness and weight. It stays securely in place even during high-speed drives or bumpy off-road adventures, so you won’t have to worry about any annoying flapping noise.

Uninstalling the MX4 is straightforward and doesn’t leave any marks on your truck bed.

Overall, the MX4 is user-friendly, enhances the driving experience, and adds a sleek look to your vehicle.

Weather Resistance And Durability

BAKFlip MX4, the company is not claiming to be an absolute waterproof cover, and they want us to know that. So, it’s essential to have realistic expectations and not assume it can withstand a monsoon!

However, if the cover is properly installed, you’ll notice that water getting inside becomes pretty unlikely. It may not keep out every single drop during a heavy downpour, but it’s designed to create a barrier that can handle most everyday situations.

Now, don’t go thinking it’s going to turn your truck bed into an aquarium during a rainstorm. That’s just not the case. BAKFlip MX4 can handle the regular rain showers and splashes that come with normal driving.

It’s important to keep things real and find that sweet spot between expectations and what MX4 can deliver. But rest assured, when you’ve got the MX4 properly installed, water shouldn’t be a major concern for your truck bed.

MX4’s weatherstripping and seals play a crucial role in enhancing its weather resistance. They do a pretty good job of keeping the dust particles and water droplets out.

Because of that, there’s less chance of water and debris finding their way into your truck bed. These seals are built to last and do a great job of keeping things dry inside.

One thing, I would like to highlight, is that it gets scratched easily if you drag anything on it so you gotta be careful.

So, to protect your truck from potential hail damage, it’s advisable to park it in a garage. This precaution helps avoid any dents or damage caused by hail.

The cover performs well in snow, thanks to its impressive weight-bearing capacity, which means you don’t have to remove snow buildup every single day.

If you are concerned about scratches and dents you can check BAKFlip F1. It features an FRP top coat and resistant to scratches, dents and UV rays.

The matte finish on panels maintains its look and doesn’t cause the color to fade for a long period of time. It is built to resist the damaging effects of the sun.

The matte black finish on the aluminum frame isn’t just there for looks, it also serves as a shield against corrosion and UV rays.

That being said, it’s always a good idea to give your truck a little care. Regular cleaning and applying a protective coating can help further shield your BAKFlip MX4 from the sun’s harmful rays and extend its lifespan.

To sum up, the MX4 offers significant resistance to weather elements, although not entirely waterproof. It combines functionality with a sleek design, providing reliable protection for your truck bed against rain, snow, and UV rays, but requires careful use to avoid surface scratches.


BAKFlip MX4, positioned in a moderate price range from $1,199 to $1,249, is accompanied by a reassuring 5-year warranty. To me, this pricing seems reasonable given the cover’s comprehensive features.

It’s capable of supporting a 400 lb weight and features a dual-layer aluminum construction. Additionally, its ease of installation and full bed access are noteworthy. In terms of aesthetics, it certainly outshines many competitors.

The inclusion of a 5-year warranty further balances the cost, making it a compelling option in its price bracket. After all, you get what you pay for, and in this case, it appears to be a great value.

Final Thoughts

In essence, MX4 is a premium looking high quality cover. Its double aluminum construction makes it durable and secure.

It has created quite a buzz with its exceptional quality and performance. It is an affordable and durable choice in the market.
