BAK Industries combines the strength and durability of aluminum panels with the scratch and UV resistance of a matte finish for its BAKFlip MX4 tonneau cover. This heavy-duty, folding cover keeps your truck bed and cargo dry, cuts down on wind drag to improve your fuel mileage, and allows for full truck bed access without having to be removed. And because this tonneau mounts inside of your truck bed side rails, you get a low-profile look and you can still use your stake pockets to mount accessories.


Convenient Folding Design

BAKFlip MX4 Cover Operation

One of the BAKFlip MX4's most attractive features is that it can be folded all the way up and remain securely positioned on your truck while you are driving, even at highway speeds. This means that you can haul large cargo without having to completely remove the tonneau. Simply unlatch each of the panels, fold them one on top of the other, and flip them back so that they sit upright against the cab of your truck.


BAKFlip MX4 Tonneau Cover Prop Rod

Then flip up the prop rods that are attached to the tonneau's frame rails, slide the brackets on the cover down over the rods, and tighten the knobs on the brackets to secure the upright cover in place. Rubber bumpers on the cover prevent it from marking your cab or scratching the glass of your rear windshield. When the tonneau is in this position, your vehicle's third brake light will remain visible.


BAKFlip MX4 buckles

If you want to maintain visibility out of your rear window, you can secure the folded panels of the cover without propping them up against the cab using the tie-down straps and buckles included with the cover. Just fold up the first 2 panels of the cover, leaving the panel closest to the cab latched in place. Make sure both buckle clips are inserted into the buckle ends on the front header panel of the cover and adjust the straps to ensure the cover is secure.


Simple, One-Person Operation

BAKFlip MX4 Tonneau Cover Operation Panel Latches

The MX4 is easy to operate. To unlatch the rear panel, drop your tailgate and pull either of the 2 release cords located along the bottom corners of the panel's housing. Either cord will release both of the integrated latches so that you can lift up the panel. To unlatch the second and third panels, pull the easy-to-reach release cords built into the corners of those panels.


To close the cover, simply fold the panels back down. Each panel will securely latch back into place under its own weight. When your tailgate is closed and locked, no one will be able to get in to open the cover, thus safeguarding your truck bed and its contents.


Heavy-Duty Construction

The BAKFlip MX4's rugged construction makes it a great match for your truck, no matter what you do while at work or play. The cover is strong enough to hold up to 400 lbs of evenly distributed weight when it's folded down, so it can support your weight if you sit or stand on it.


BAKFlip MX4 Tonneau Cover Panels Close-Up

Although it appears to be one piece, the cover is made up of aluminum panels that are lightweight but strong. The panels have been enhanced with premium density foam for added strength.


The MX4 is covered with a black matte finish that provides protection from the elements. It resists scratches, scuffs, and harmful UV rays.


Easy, No-Drill Installation

BAKFlip MX4 Tonneau Cover Installation

Installing the MX4 is simple. All you need is a wrench, and you don't have to do any drilling. The tonneau's frame rails clamp to the inside of your truck bed side rails to create a base for the cover. The included bolts secure the front hinge rail to the frame rails at the cab. Slotted brackets on the hinge rail allow the bolts to shift in case you need to adjust the cover to achieve a snug fit.

I have owned this cover for over a year and it has been excellent. It keeps the bed fairly dry as expected and I have had no mechanical issues with it as it still performs like new. I would say the only improvement I would suggest is better foam weather striping for the front of the bed as the original never stuck to the spray in liner very well and eventually came lose and then I just swapped with some similar weather striping I bought locally.



by:

The cover functions ok. The tailgate leaks quite a bit. The manufactured edges that where cut were sharp and not painted or treated. The weather strip along the edges has already discolored/faded. Disappointed in the fading and less than ideal sharp edges. Somewhat expected leaks, but not this much. Average at best rating, especially for the price.



by:

Cover went on easy and looks good on the truck. We put it on our 2020 Colorado which we tow with our motor home. It works great for extra secured storage. The only problem was with the rubber bumpers on the bottom and the two on top , fell off as soon as I opened the box. Not a big deal just had to use a little gorilla glue on them and all has been good.



by:

I have been using this cover for almost a year now, and am very pleased with it. It looks and fits great, and it is secure and keeps most of the bed dry in the rain. A couple of rubber trip bits have needed some improved securing, and I used a little RTV so it was easy. I drove it across the country round trip last summer and it was perfect. I would recommend this cover for a great-looking and pretty secure cover. Finally, it is easy to fold forward when it is time to haul loads taller than the bed rails.



by:

Overall, I am very pleased with my BAKFlip MX4. It has held up well after 1 year. It works well and looks good. It matches my matte black accessories and trim. It was fairly easy to assemble but I did have some tight fitment issues near the cab where the cover connects to the rail. I really like the security of the hardtop and access through the tailgate. Water is generally kept out, but sometimes there are water drips near the tailgate depending on the angle parked. So this cover keeps the bed *mostly* dry.
etrailer was very fast to deliver my cover, and it came in good condition.



by:

Well made cover. A lot sturdier than I thought it would. Its not full proof so water does get in the bed but it's minimal. The cover partially blocked my tool box which sit in the bed, so I removed the tool box cover for easy access.



by:

So after a year I am still loving this bed cover. Had the fiberglass version for my 2013 F-150 and loved it as well, that's why I purchased this one for my 2019 Super Duty, it was also the first accessory I purchased for it because I was so used to my other one and knew I couldn't live without it. I never installed the drain tubes on either covers and still haven't had water get it my bed. Also the folks at etrailer are always awesome! Thanks again!



by:

Easy to install. Doesn't leak. Easy to clean, and seems to have improved my fuel mileage a bit. I am happy and would highly recommend this cover. Fits my 2018 Silverado perfectly.



by:

I installed the BAKFlip MX4 in my RAM 2500 Crewcab has the 6' 1/2 short bed, drived 300 miles now. good product, open and close the tailgate without lifting up the cover



by:

Overall satisfied with it. However, the end caps get loose and we lost one within a month. I contacted BAK manfufacturer but have not heard from them. Rather poor service.
Other than that, the only other problem is that the middle hinge often closes with misaligned plastic piece, easy to spot (hinge is buckling) and press the piece into the the rail.



by:

I am a huge fan of the BAKFlip. The installation was pretty straight forward and easy. Anybody with moderate mechanical ability can install. I think it took less than 2 hours. I live in a heavy snow area and had more than 24” of snow on it at one point and the product performed flawlessly.



by:

the bedcover finally came in.
Few pictures
of it installed.



by:

I really love the bakFlip cover. It locks up all my stuff when we are on the road. I really like the looks too.



by:

This tonneau cover can be installed by one person. It works great. It is water proof in the rain.



by:

Solid performance. Only issue is with the glue holding the pads is failing



by:

Love the MX4 ...Took a little longer to install but looks great...



by:

This is the third MX4 that I have owned. This one is on Ford’s Maverick. The first two fit well but not perfect. I don’t really know if the slight issues were the fault of the truck or the cover. This cover is the best yet. Absolutely no leaks!! The fit to the tailgate is very uniform!! When ever I need a cover, I don’t even look at te competition. These are great covers.



by:

After a year of using the cover I found that there are a few things that could be improved and you can do some of these yourself.
The knobs for the cover that actually hold it into the bed-vibrate loose. I added my own lock washers. The poles that you use to hold the cover up when the cover is raised up against the back window-they also vibrate loose-so often that I just removed them and keep them under my seat. The little u-clip pole holders for the poles when not in use-they are too weak-often letting the poles jump out or fall out during normal road driving.
The cover itself is not waterproof --it sheds water away mostly however enough gets into the bed that you can not trust your items to be dry. Bag important stuff to keep it dry.
The rear weather seal slides back and forth too easily--sometimes working itself out about 2 inches until you see it and slide it back into place--i addenda small amount of silicone to stop this from moving.
The cover is strong, looks good and is mostly what I was looking for. Unfortunately I would not buy this again-even more because you have to relocate the bed accessory rails-which then limits the items you can buy for your truck because they are designed for the rails to be in the factory positions.
My next cover will be a roll up so that it allows visibility out of the back window. When this cover is flipped up to its final position it completely blocks the rear window. When I was looking at covers-my thought was well its the coolest looking cover and I can deal with not seeing out the back window--well that has changed. It is not practical. The price is high and there are many other options out there that are. My soft roll up tonneau cover was great-waterproof and I could have bought 6 of them for this price. If one was damaged it would have been better to just throw it away and order a replacement. Sorry guys-look elsewhere for a better cover.



by:

I've had the cover for one year now and the cover has gone through the worst California winter weather for the last 3o years. It kept my stuff 99% dry! It's not 100% leakproof and that was expected but given the conditions esp during rainy season, it has performed above expectations.



by:

I love the cover, very sturdy and has held up very nice for 1 year. The one issue is, I have a long bed Ram and when I fold it up against the cab, it covers the camera for the bed. This is a design flaw and if you use the bed camera when you have a load in the bed and the cover is folded all the way up, you can't use it.



by:

It's a straight forward assembly but photos of the assembly steps would be better than the illustrations.
NOTE: This model allows you to open and close the tailgate without lifting up the cover. The other models require you to lift the cover so the tailgate won't damage it.



by:

This is the second BAKFlip i've owned they vare great,going thru etrailer is an easy process



by:

this was easy to put on, no problem.
you
can see in the picture it looks great on my gmc canyon!



by:

All is well....except, the caps at the joints of the folds keep popping out of place. leaving unsightly bludges in the top. With some work you can pop them back in place, sometimes easily sometimes not. Overall pleased, this is our 2nd BAKFlip and would purchase again.



by:

Excellent cover for the truck. Easy straight forward install. Built to outlast the truck.
