Features:
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
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.
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.
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
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.
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
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 really love the bakFlip cover. It locks up all my stuff when we are on the road. I really like the looks too.
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
I am very happy with my BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish - BAK48203. Really. And the service I received in its regard was top-notch. It did arrive with a non-functioning blemish but I was compensated by the company, immediately. Also, a part broke shortly after I installed it and again, the company stepped up. As for the tonneau cover itself: •it folds open and closed easily as advertised, •I can stand on it if needed, •it keeps out the rain (I've run it through car washes too, and the contents of the bed remain dry, •it was easy to install •I love that concern for locking the bed by closing before/after tailgate is not an issue.
The BAKFlip MX4 was easy to install, and does what I need. I like the new style where I can close my tailgate without having to lift it.
it looks nice, functions well, but leaks like a sprinkler.
Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
Installation was easy, although it has never aligned perfectly. It has worked well, although it has been designed to be usable in the open position with the last panel (closest to cab) closed and the folded portion strapped into position. I bought it specifically for that so I could access my 5th hitch and tow, with a portion covered. It seems to be stressful on the cover to use it this way…all of the foam bumpers have worn off and have even put some dents in the cover. It’s a great concept, but could use some design tweaking.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
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!

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.

One of the best things I have done and the BAK flip is great

I like the tonneau cover a lot! It's sturdy and helps keep belongings out of sight, out of mind. I had to cut the rail as it was about an inch too long for my truck but besides that the install was easy.

Works great and 5th wheel hitch fits underneath and when folded up I can hitch up my trailer without removing cover. Only issue is the corner pieces on the end section came off and I can’t get manufacturer to help me get replacement.

Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
I am so happy I purchased this BAKFlip. The installations were perfectly understandable which is a big deal to me and the actual installation was easily completed. I did need my wife to help tighten two screws but otherwise I completed the job without assistance in about one hour. After using the BAKFlip for approximately one year I haven't needed to make any adjustments to the product and it works perfectly and looks new. I believe having the BAKFlip has made my personal property in the truck bed more secure in addition to being out of sight. This product has exceeded my expectations and made me very happy. I would purchase this again without hesitation.

Love the MX4 ...Took a little longer to install but looks great...
Sherry H - 05/19/2020Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
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.

Love the BAKFlip. Well-built and easy to work. I did notice, however, that I need to be careful with the foam padding that is attached with sticky tape. It does not always hold. As a result, I have to stick it back on. Will have to figure out a way to make them stick better. Otherwise, I love it!

I've had it for a year. Easy install, but more sturdy then you would think. Only complaint is that one of the plastic buckles broke. Otherwise, great product, as advertised
Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
I had a some trouble putting it on since I had a bed liner on my 2017 Ford F-150. It did have a long scratch on the black paint which is not seen unless I flip it up against the back of the truck cab. Overall the construction quality is very good and it looks like it should last five to eight years under my type of moderate use.
Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
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.
Martin Z - 09/19/2018Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
Fits perfect, looks great and virtually waterproof. Be careful, it can dent rather easily.
Lee V - 05/09/2021Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
This is my second Bak-flip bed cover. First one (aluminum) was on an F-150, second (fiberglass) on a Nissan Frontier. Both have been wonderful, and almost completely leak-free. Only place water has ever gotten in, is at the back corners near the tail gate, and that was only at the car wash. Installation was a snap, and operation has been flawless. Only thing that I would like different is an optional window in each panel, so when it's folded all the way up, you could see your load in the rear view mirror. You know, to make sure it's still there. I recommend getting the fiberglass over the aluminum, if you live in an area where hail larger than pea-size is a possibility. Great product.
Review from a similar BAKFlip MX4 Tonneau Cover in Tonneau Covers
Love the look and the fit of the BAKFlip MX4 but after a light hail storm it is riddled with dents. My 2018 GMC has no damage but the cover does. Bummed.....
