I'll share all my trucking experiences (both great and gross ones) with you. I have a garage full of tools to fix and renovate trucks and a freezer full of ales. Do you want to join me?

Bakflip Fibermax vs Undercover Flex Tonneau Covers: Differences that matters

It’s time to get in details. You already know some of the most prominent differences. Let me tell you how they can make a difference in your truck.

Materials Look/Finish

This is the factor that matters the most. And sometimes the preference depends on it alone.

Undercover Armor Flex is constructed of Aluminum Panels. These panels are both durable and lightweight at the same time. You will find them covered with Line-X Matte Black Finish. 

With Line-X finish, you can protect the panels from harsh elements with tough, durable coatings. Your truck will look more stylish and low-profile with the cover. This will also protect your truck bed and cargo from any kind of heavy impact and damage.

On the other hand, Fibermax covers are made of heavy-duty aluminum panels covered in high-gloss FRP (Fiberglass Reinforced Polymer). You can forget about any scratches or dents with this material.

Also, the glossy black appearance of this material makes it look great in the sun on a bright day. With its FRP surface, the surface won’t be too hot to touch.

Safety Features

Bakflip Fibermax features a latch and hitch system you’ll love. You can keep your cargo safe with all these features on this tonneau cover.

The FiberMax cover has a durable aluminum substructure, robust hinges, and a patented slam latch system. You can operate it from either side of the truck with its sleek, contemporary design.

On the other hand, Undercover Flex Tonneau Covers are featured with Dual Action Tailgate Seal. This seal allows you to close and open the cover even with the tailgate locked. 

The action and operation are way simpler. 

Water resistance

No one wants to see a puddle in their truck bed and their stuff wet and damaged. The fully waterproof tonneau cover is a myth, but a tonneau can be amazingly water-resistant. 

Keeping that in mind, these covers are equipped with EPDM rubber seals. This seal resists water from entering the cover. But in heavy rain or snow, a few drops may enter the cover through these seals. 

For that, Undercover Armor Flex comes with Draining plastic tubes. These drainage tubes sit on the cover rails and drain any water that might have leaked through the seals. In any case, there’s no chance of creating a puddle.

On the other hand, Fibermax comes with Integrated water drainage rails. It is more effective to drain water with these drainage rails. With these integrated drainage systems, water is channeled away from your bed and covered, so there will be no puddles on your bed.

Weight Capacity

This is the game-changing feature when comparing two great tonneau covers.

BAKFlip Fibermax is capable of carrying evenly distributed 300lbs of weight. It is one of the favorite choices of professional truck owners. They can easily carry their stuff on the cover if necessary.

Professional mountain bikers can carry their bikes on the cover if wanted. As mountain bikes are super lightweight, you can carry multiple bikes on them. You can also carry your professional tools on the cover if evenly distributed.

On the other hand, Undercover Flex has a weight capacity of 400lbs. A 100lbs more weight capacity may not seem like a lot. But the preference based on this small difference can change entirely.

For professionals who always have to carry their heavy stuff and are always in a hurry, this is the perfect tonneau for them. Moreover, if you don’t want your truck bed to get dirty by carrying them on it, Flex is the best choice.

Price Range & Warranty

This factor is the second decision-making factor you will face while comparing Bakflip Fibermax Vs Undercover Flex Tonneau Covers. Because budget and value for money are extremely important when choosing a tonneau.

If you want to go for  Bakflip Fibermax, this tonneau may cost around $1000. Along with this, you will get a 3-years warranty. As it is a product of Bakflip, you will also get hassle-free after-sale services.

For extended warranty time, Undercover Flex is a perfect choice. It comes with a 5-year warranty. However, it might cost you around $1200.

But keep an essential factor in mind-actually three.

  • The cost can vary due to some situations. It can vary from website to website. You may find a price stated on website A, which may seem different on website B.
  • The cost can also vary from shop to shop. You might get the best price if you get your tonneau from an official dealer. But if you are getting it from a local auto shop, you could get a sale offered by luck. Otherwise, these shops might put a higher price tag than the dealerships.
  • Last but not least, the weather conditions or season. Because of the weather or season, the demand for covers may rise as well as the price. 

Compatibility

Based on compatibility, you should make your decision.

If you own a  2020 – 2023 Chevy or GMC Silverado or Sierra 2500/3500HD truck, then Undercover Flex Tonneau Cover will be the best choice.

But if you want to go for Bakflip Fibermax, you have to have a 2002-2018, 2019-21 Classic Dodge Ram 1500, or 2003-21 2500/3500 truck.

Now it’s up to you for which truck you want to choose a tonneau for.
