Undercover Armor Flex Review – A Detailed Look

Key Features & Specifications

People usually ask many questions regarding the features and mechanism of the Tonneau covers. According to my analysis, people mostly get confused during the installation of the Tonneau covers. Many people ask me about the Under Armor Flex Tonneau cover; How do you install an armor flex bed cover?

Armor Flex is more than just a pretty cover. It’s also incredibly easy to use, with a simple and secure latch system that allows for one-person installation and removal. And when you need to access your truck bed, the cover can be easily folded up and out of the way, giving you full access to your cargo.

I love the structure of Undercover Armor Flex. A rugged folding tonneau cover made of aerospace-grade aluminum panels. The best scratch protection is provided by a matte black Line-X coating, which is also UV resistant. So this can bear the intense sunlight and other drastic weather challenges.

Does UnderCover Flex leak? My answer is No; an advanced operating system in the undercover flex leads the water outside the bed. The Armor Flex incorporates EPDM rubber hinges and seals for ultimate resistance to rain and debris. 

Why UnderCover ArmorFlex?

By directing extra water via the included drain tubes, the tonneau rails also help keep your goods protected from the weather. Usually, some covers require drilling holes in the truck bed rails. They also generally required extra effort for their settlement on the truck bed. 

But what I found in the Undercover Flex is, Due to its clamp-on construction, they are easy to install without the need for drilling. Only simple equipment like a socket wrench is required for most automobiles to finish the installation.

Another prominent feature that provides me with much ease and relaxation in cargo management is the complete exposure of the truck bed. The Armor Flex’s fantastic feature allows complete bed access without taking off the cover. 

Panel by panel, just fold the cover to the front of the bed, then fasten the prop rods to keep it standing. Driving the truck at highway speeds is safe while the lid is in this position.

Now let me tell you about its lock system. The undercover armor flex cover has a dual-action tailgate seal mechanism. Using this seal, you can close the tailgate without first opening the cover and the cover without lowering the tailgate. 

Know about locking techniques: How do I lock my truck cover?

Both sides of the bed can use the automatic slam latch, which opens from either side and locks the cover as it shuts. These qualities provide the cover with a flexible motion and make it simple. Undercover guarantees that this cover is free from manufacturing flaws for five years.


  • The slam latches on either side for use assist.
  • Dual Action Tailgate 
  • Seal with Drain Tubes 
  • Aluminum Panels for Enhanced Security 
  • Line-X Matte Black Finish for Ultimate Protection 
  • No-Drill Installation 
  • EPDM Seals Provide Maximum Water Resistance


  • Sometimes any of its areas got broken during the delivery, so always try to bring it by yourself.

Unboxing and Application:

Differences between Undercover Armor Cover with Others

As a Tonneau cover reviewer and expert, I have to compare and then make an analysis according to the comparison ratio, in the case of the Armor Flex Tonneau covers. Several aspects need to be addressed. 

In the case of accessibility, durability, and lock mechanism, people mostly ask me to pass some comments about the undercover armor flex vs ultra flex. So, several things require a detailed discussion. 

But I think there is no prominent difference between these two Tonneau covers. The only difference which can be particular in the GENERAL price of the Undercover Flex is a little bit higher than the Ultra Flex.

I found both Ultra Flex and Armor Flex very efficient and reliable. I used both of them very frequently, and they performed outstandingly, I have also used a BAKflip mx4 cover. The main difference between the undercover and Bakflip is Armor Flex is much better than the BAKflip Tonneau cover. 

They are more reliable in many factors compared to the BAKflip mx4. Both covers perform well, but other aspects also get changed with the price change. So, according to my perception of the difference between these two Tonneau covers, you should buy the Undercover Armor Flex Tonneau cover if you can afford it.

Another relevant analysis of this cover is with the BAKflip G2 Tonneau covers. I also used that cover and found it good in several aspects but not as much as Armor Flex Tonneau covers.

G2 Tonneau cover may be good in manual locking and override switch, but this cover is not as good as the Armor Flex in easy installation for beginners. Armor Flex is also quite efficient in resisting the water and weather.
