Why is BAKFlip MX4 So Popular?

The BAKFlip MX4 is highly popular for several compelling reasons:

1. Easy to Operation

There are no features missing from the BAKFlip that truck owners would want. With four panels for extra-long beds, this tri-fold tonneau cover is low-profile. Pulling on either cable-pull release will open and release the tailgate. Using cable pulls, each panel may be locked into position and then unlocked. This adds further security to the BAKFlip MX4 along the mounting rails and keeps the panels from being lifted up by strong crosswinds.

Big cargo can fit in your truck bed thanks to the panels’ ability to fold over on themselves. In order to access almost the entire bed, you can either leave the folded-over panels lying horizontally on top of the final panel (secured in place with a strap as you drive along) or fold the panel over one more time so that it stands up against the truck’s back cab window. The tipped-up panels are held in place on either side by a strong lock-rod system.

Additionally, BAKFlip comes with rubber molding that is adhesive-backed and fastens to folded panels. Place the molding in the recommended location to prevent chafing or other damage between the folded panels and the rear of your truck cab. The cover is significantly simpler to unfold. The panels automatically lock into place as you draw them over. With the tailgate up or down, the last panel latches.  

2. Great Materials, Great Construction

The BAKFlip MX4’s lid and side rails are made of a sturdy aluminum alloy with a matte black finish. 400 pounds of equally distributed weight may be supported by the cover thanks to its strengthened aluminum frame. Almost anything can be carried atop the MX4. The BackFlip MX4 makes it simple while you’re working on a weekend project as well as safeguarding your work vehicle.

We’re also discussing specifics here. No exposed aluminum is present. The entire design is modern and all-black, just as you would like your truck bed cover to be. 

Aluminum does not refer to the kind found in foldable lawn chairs either. This aluminum alloy is of the aircraft grade. You may feel confident using it to cover the truck bed if it passed FAA inspection since it must be strong enough to survive their scrutiny. 

Specialized rubber is used to make anything that isn’t metal. To cover the hinges and completely seal the MX4, BAKFlip employs EDPM rubber. The three major components of this mixture are ethylene, propylene, and diene monomers, or EDPM. 

The combination of these three results in a synthetic rubber with a single bond and a molecular structure that is perfect for usage outdoors and over time. EDPM is very flexible, resistant to UV rays, water, and the ravages of time. Even if your truck is an outdoor vehicle that hardly ever enters a garage, it still performs its function and is aesthetically pleasing years later. 

3. Security

Before we discuss the BAKFlip and how it prevents criminals from entering your truck’s bed, let’s briefly discuss security. Tonneau coverings that are impervious to theft are quite rare. In actuality, very little is theft-proof. Any lock or anti-theft mechanism may be defeated by a competent burglar who wants something badly enough. 

Your objective is to avoid drawing attention to whatever is in your truck bed and to make things challenging for anybody who decides to break in. If you are successful in your mission, the thief will go to the following truck in the parking lot.

The BAKFlip MX4 is able to do this. If you have a locking tailgate and the panels are fully extended, nobody can see inside your truck. No one will be aware it is available for theft if you don’t publicize it. Against the side rails and the tailgate, the final panel locks into place. 

By pushing on the recessed cable pulls at each end of the rear rail, you may remove the panels. Only when the tailgate is lowered will you have access to these cable pulls. So, if your truck bed has a locking tailgate, you’ve been successful in making it hard to break into. 

4. Leaks

Tonneau covers are not totally waterproof or theft-proof, just as they are not completely watertight. When you read the tiny print, you’ll discover that the majority of manufacturers are cautious to make this distinction. They are just water resistant. 

However, the BAKFlip MX4 is known for being among the more water-resistant tonneau covers available. There are not many grievances. The installation is the key to having a water-tight tonneau cover. Take your time and adhere to the guidelines. Each side rail of the BAKFlip MX4 has a channel that is designed to capture and divert runoff.

At the front of your bed, there are two drainage hoses where the water can exit the side rail or enter one of them. The hoses stretch down to outlets in your truck’s bed that are intended for drainage, and they tuck discreetly into each corner of the bed up against the bulkhead. 

Once the installation is complete, put it through an automatic vehicle wash. Those sprayers are excellent for aiming water to the bed of your vehicle from all directions. The carwash will locate any leaks you may have. To discover whether you missed a step, double-check your installation. 

5. Durable 

In our experience, this tonneau cover lasts a very long time. It withstands daily usage and repeated use. The seals and weatherstripping are not weakened by repeatedly folding and unfolding the panels or opening and shutting the tailgate. You will have a tonneau cover like this for a very long time. 

Even if you reside in one of these states where the sun never sets, the black-matte finish still looks like new. Specifically, we’re referring to Florida, Texas, Arizona, and California. On the market are preservatives. Apply one of those periodically if you want to practice some preventative maintenance. When the seasons change, we advise doing it. 

Insulation and molding do deteriorate. The insulation may become thin after four or five years. Make an effort to prevent clutter like dirt, leaves, and debris off the molding. It will quicken the procedure. And the majority of moldings are simple to repair if they do wear out.

6. Warranty

The BAKFlip MX4 tonneau cover is a reliable one. In fact, BAKFlip offers a five-year warranty on it. Executives of the company are aware of its brand’s strength. There are multiple accounts of BAKFlip delivering replacement components, and even completely new covers, to customers who were having issues.

How does the BAKFlip MX4 compare to its rivals?

The MX4 has proven to be such a brilliant tonneau cover that even BAKFlip has tried to imitate it, proving the adage that imitation is the highest form of flattery. 

Which choices are better?

1. The MX4 vs. F1 BAKFlip

Actually, not much distinguishes the FI from the MX4. The F1 features a composite core that is sandwiched between top and bottom sheets of aluminum, as opposed to the MX4, which is constructed of aluminum and supported by an aluminum frame. The outcome is the same: a 400-pound weight rating with equally distributed weight. 

What makes a difference, then? The F1 costs between $1,169.00 and $1,219.00 and features a gloss black finish. Some people might believe that the name makes your truck stand out from the competition and is a little bit cooler. The rationale is that it is not an MX4. This is an F1. 

2. MX4 vs. BAKFlip G2

The BAKFlip G2 is the MX4 light, yet there isn’t much quality loss. For individuals who don’t need to carry the entire world on top of their truck cover, the G2 could be the solution at a cheaper price point—$909.00 to $1,099.99—because there is a little less metal in the support frame.

All of the panels lock into place, and it has a matte black surface. Additionally, you continue to receive a three-year guarantee and the fantastic BAKFlip brand.

3. MX4 vs. BAKFlip Fibermax

The gap between the G2 and the MX4 is filled by the Fibermax. The panels have a three-year guarantee and can support 300 pounds of equally distributed weight since they are composed of fiberglass-reinforced polymer. It has a gloss black finish. 

Most BAKFlip products have a solid reputation and excellent customer service, but when they introduced the MX4, they nailed it with a tri-folding tonneau cover that practically everyone appreciates. 

BAKFlip MX4: Real World test

According to the auto expert in the video, the backflip material is quite nice. Once they fold the cover up this part would crack. There would  be a physical crack in the rubber alongside here causing leaks in the plastic clip holder. 

This one feels extremely solid and there are four end caps on each side of the cover at the end so the rubber strip doesn’t peel up. This cover is that you can open and close the tailgate first cuz there’s a Rubber seal on the edge here so that’s a bonus you don’t have to close your tailgate before you close the cover let me hop on the tailgate. 

The Rubber seal that touches the tailgate it’s quite soft and the material seems pretty good with this foam padding here so it sits on the next cover so it won’t scratch padding all along the way the steel cable is covered with a plastic coating.

It would be like metal strips coming off it which pokes your hand when you grab it and the string even falls off so I have to take off the screws to get it fixed where it is.

This one feels quite solid, nothing is rusting yet so that’s a bonus so as you can see when you pull the string it pulls the clip back so you can lift it up.

When you fold the second part there’s a clip that you can adjust the locking into place for both sides so when you’re on the highway, stuff will fly back over and hit whatever you got in the back.


1. Do I need to adjust the cover every time I open the tailgate?

Opening or closing the tailgate does not require you to adjust the cover. You can close the tailgate of the Bakflip MX4 with the cover up or down thanks to an incorporated tailgate seal feature.

2. Can I drive when BAKFlip opens?

Yes. The brand-new straps and buckles are now considered standard on new BAKFlip models. The bed can be partially accessed and rear window visibility is enhanced by strapping the cover flat to the rails behind the cab.

3. Does my BAKFlip require a dealer to be installed?

No. BAKFlip is simple to install if you’re a weekend mechanic and have a few basic tools.  Typically, installation takes 30 minutes.

4. If my truck lacks a tailgate lock, how do I lock the BakFlip?

Easy. Although it appears like every new vehicle has an OE tailgate lock, if your truck doesn’t, a Pop & Lock or other comparable lock can be added to your truck to complete the bed security.

5. Can I drive my trucks while the BAKFlip is flipped up?

Yes. The BAKFlip’s design includes the ability to drive with the device flipped up against the cab. You can drive with the cover open at safe highway speeds by locking the prop rods to keep them open on both sides.

6. Are the BAKFlip truck bed covers simple to remove?

Without the need for tools, BAKFlips can be removed by using a single pin on each side and a thumbscrew underneath.


In conclusion, our BAKFlip MX4 review reveals an exceptional tonneau cover that excels in durability, functionality, and security. With its rugged construction, user-friendly design, and outstanding real-world performance, the BAKFlip MX4 is a top choice for truck owners seeking both style and protection. Don’t miss out on the BAKFlip MX4 – a game-changer for your truck!
