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. 434169

Product was straight forward install, thought the fit and fair is good quality. I dont like how flimsy the topper is at the back near the tail gate. You can lift up at the back even with the tailgate closed. Hope it is secure and somebody wont try and force it open seems like it would pop open without much force. 583199

Review from a similar BAKFlip MX4 in Tonneau Covers


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. 591725

Review from a similar BAKFlip MX4 in Tonneau Covers


My 15 year old and I installed the BAKFlip MX4 in less than 20 minutes. My RAM 1500 Crewcab has the 5'7" short bed with a factory drop in bedliner and this cover fit with a 1/64" too spare. I thought I might have to trim the rails, but no; it was designed to accommodate the bedliner. It looks good, fits well, is easy to operate, and is quite sturdy. Overall a quality product and I am quite happy with my purchase. Not too mention that the folks at etrailer provide great service all around making the whole purchase and installation an enjoyable experience. 479342

Review from a similar BAKFlip MX4 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. 739740


Comments
Im sorry to hear about the issues youve had with your BAKFlip MX4. If youre looking to go back to a more traditional style, soft roll-up cover, I recommend checking out the Access TonnoSport # A22050279
Access TonnoSport Soft, Roll-Up Tonneau Cover
$301.88
because it checks a lot of the boxes of things you liked about your previous cover. The TonnoSport is a soft roll up cover that is on the affordable end of the spectrum. It also includes brackets to mount into the OEM rails while they are in their original location.

Review from a similar BAKFlip MX4 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. 523899

Review from a similar BAKFlip MX4 in Tonneau Covers


well, two things that made it be a three star. On your ordering system for a Nissan titan you ask if it has the utilitrac system, I clicked on that, thinking that , there would be some kind of special adapters or something to fit the two together. There wasn't anything out of the ordinary, ( I guess I should apologize for not having an f-150). Anyway I had to take off the rails , for which anyone that has done that will know that the bolts are extremely difficult to remove, they are locktight in, and the bolts require a star wrench. Some of them I simply could not remove with the wrench, but had to grind the heads off to get them out. The other thing that was and still is annoying is the, prop rods do not fit in the slot with out bumping up the locking holder past the rivets, for which I have to get a wrench every time to do that. Not a lot of work to do that but it just doesn't seem right. 597972

  • What Ladder Rack Will Work with the BAKFlip MX4 Tonneau Cover on a 2020 Ford F-350 Super Duty
    We do have a ladder rack solution for your 2020 Ford F-350 Super Duty with the BAKFlip MX4, part # BAK48330 for short bed or # BAK48331 for long bed, but you are correct that the vast majority out there use a clamping system which makes them incompatible with most tonneau covers. For your application you can use the Adarac Pro Series Ladder Rack, part # A4000952 for short bed or # A4000958 for long bed, because it uses an anchoring system with the stake pockets instead of a clamping...

  • Tonneau Cover Recommendation for 2018 Ford F-350 Short Bed with Fifth Wheel Hitch
    The BAKFlip MX4 part # BAK48330 that you referenced has 4 equal width sections that cover the truck bed. Since your truck bed is 6-3/4 feet long each section will be 20-1/4 inches wide. The other thing you need to consider is the heigth above the bed rails this cover adds when folded up and the potential for clearance issues between it and the overhang of the fifth wheel trailer. You'd need 6 inches between the cover and the trailer overhang at least. The RetraxPro part # RT80386...

    The best tonneau cover for a 2019 Ford F-350 is the BAKFlip MX4 Hard Tonneau Cover part # BAK48330. I prefer the BAKFlip MX4 because it has a hard top which means your contents inside the truck bed are truly safe, it has a low profile design so you don't have to worry it sticking up from the bedsides taking away from the look of the vehicle, and it is very durable therefore you don't have to worry about it getting damaged when using your truck as a truck.

  • What Is The Dimension Of The BackFlip MX4 When Folded Up On A 2017 F-250 6-3/4 Foot Bed?
    The BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish, # BAK48330, is a quad-fold cover. I reached out to my contact at BAK industries and for your 2017 Ford F-250 Super Duty with 6-3/4 foot bed, the depth of all the folds together is 3-4 inches. Each panel is 1/2 inch thick but there are also the support rails. They were unable to give me the dimension exactly for this specific cover when resting on the panel closest to the cab, but that would remove a 1/2 inch....

    Thank you for all of the info! You do bring up some excellent points and while I wish I could tell you that the BAKFlip MX4 # BAK48330 will work, you are correct that you'd have clearance issues so you'll be better off with a different cover. There is a similar cover from BAK Industries with their Revolver X4 # BAK79330. These covers have the same look but the main difference is that that Revolver is a roll up cover as opposed to the folding style of the BAKFlip. The Revolver is still...

    You would be able to install the TracRac SR Ladder Rack part # TH43002XT-508 with the BAK MX4 Tonneau Cover part # BAK48330 but the issue will be that the base rails of the ladder rack are going to interfere with the tonneau cover folding up.

    Usually ladder racks use the inside edge of the top of the bed site to attach to the vehicle, but luckily there are exceptions to that. The Thule TracRac SR is typically compatible with tonneau covers that mount to the inside edges of the truck bed. I spoke with my BAK Industries representative, who confirmed that the SR will work with the BAKFlip MX4 on your truck. The correct Thule TracRac SR for your short bed F350 is part # TH43003XT-785.

The biggest being that the G2 has three sections that fold and the MX4 has 4. The MX4 is also compatible with the BakBox which is a storage box, part # BAK92100. The MX4 also has a weight rating of 400 lbs evenly distributed on it while the G2 isn't rated at all.
