Description

America’s best-selling truck bed cover just got even better.Introducing the BAKFlip MX4 Gen 3—the latest evolution of RealTruck’s most popular tonneau cover. Now better than ever, the BAK has redesigned the for improved strength, security, and all-weather performance. The Gen 3 MX4 features alloy-based construction, including heavy-duty aluminum side rails and top panels, reinforced with high-density polymer cores. This updated design delivers a 22 percent increase in strength over the previous generation, making it even more capable of handling daily use, heavy loads, and harsh environments. Security has also been upgraded. BAK’s patented auto-latching system secures the cover automatically when closed. Newly engineered lock components provide added resistance to tampering and forced entry, allowing you to transport your gear with confidence. In rough weather, the Gen 3 MX4 holds strong. Revised EPDM perimeter seals and tight-fit clamps offer the best seal yet, helping prevent water intrusion along the bed rails. A longer dual-action tailgate seal weatherproofs the tailgate while preserving full functionality, whether the cover is open or closed. While the MX4 is built tough, it doesn’t compromise on looks. The flush-mount design gives it a sleek, low-profile appearance, while a textured matte-black finish across all surfaces delivers a clean, subtle aesthetic. Installation is easier than ever with a new click-in rail system that cuts install time by up to 12 percent. Day-to-day use is just as simple—drop the tailgate, unlatch, and fold the cover forward. For complete bed access, fold the cover against the cab without blocking your third brake light. The BAKFlip MX4 Gen 3 is proudly assembled in Missouri using globally sourced materials and backed by a 5-year warranty.

    • Easy to install. Impressed with the fit on my F250.
Style: BAKFlip MX4 Size: 6' 10" Bed
Review Image by Dobster Dobster
Really nice fit. Easy to install. I like that it cannot be opened without opening the tailgate. If your tailgate locks, the cover will be secure. No cover is completely water tight. Have not tested it with a wash or rain yet but judging from how it looks, I bet this is one of the best covers when it comes to keeping your cargo dry. Looks great on the truck. Very happy with my purchase. Plus saved $100 by purchasing on Amazon vs one of the other online truck accessory dealers. For installation, read the printed directions AND watch the YouTube video. It’s only 7 minutes long but will insure a perfect fit. I rarely do reviews. But this one ranked 5 stars!! Thank you BAK Industries for a nice product! ... show more

    • Installation can be done DIY but.....
Style: BAKFlip MX4 Size: 6' 10" Bed
Was looking for a hard style bed cover for my 2024 SuperDuty Truck. This unit while pricey fit like a glove. There is a great you tube video showing installation. Keep in mind the video doesn't explain the clamp direction and the importance very well. The clamps have two ways to install. Right and Wrong. If correctly positioned will start at 45degree that straightens out very quickly when tightening. This is the only way they fit correctly. Thus far no leaks and it seems to be well made. Be advised the delivery truck is large for this item. I guess due to the weight. It would have fit very nicely in a Prime Van but instead comes in a 20' large box truck and not sure why. Challenging delivery ... show more

This is my 3rd BAK Revolver X4S on my 3rd Ford F-250 8’ Bed. After researching every other product on the market, I keep coming back to BAK. Their products are extremely well designed and install easily. Their product adds safety, security and beauty to your beloved truck! I was able to install it myself in about 45 minutes and it lined up and fit perfectly. No permanent holes needed for the Revolver X4S, and it can be removed later very easily and quickly (although I have never had a reason to remove it because it rolls up and is kept in place by straps that are provided. You do not lose any area in the bed because it rolls up on top. This is a huge benefit to people like me that use their trucks for work, constantly going into Home Depot or Lowe’s and don’t want to get ripped off. My prior experience is that they are not 100% water tight, however, they do keep your tools dry! One additional huge benefit is that you can install a Adarac ladder or sport rack without interfering with the operation of either. ... show more

    • Nice cover
Style: BAKFlip MX4 Size: 8' 2" Bed
Just installed it on 2024 F-350 long bed. Need to follow the instructions closely. The rails were the most difficult to assemble, rest was easy. It took me four hours to install, mostly assembling and installing rails. Appears well constructed and nice design, time well tell. I didn’t give it five stars, it took over ten days to deliver. ... show more

    • Good looking product worth the money I paid for
Style: Revolver X4s Size: 8' 2" Bed
I bought this product to be installed on my 2024 F350 Lariat 8FT Bed. It was an easy installation all the tools needed is a 9/16 wrench and a box cutter. From un boxing to installation it took me about an hour or just a little bit an hour. The manual that came with this product is clear on the direction on how to install the this product. Over all its a great product and it looks good. I will update this review in a few months to see how it holds but for not I am giving it full marks on installation and product. ... show more

    • Unsafe, needs propping up, and/or flimsy.
Style: BAKFlip MX4 Size: 8' 2" Bed
I don't care for the clamping system that is used, they utilize the grip of the clamp to hold the rails (and thus the entire tonneau cover) to the truck bed. The clamps otherwise are not physically attached to the rails, and if the nuts happen to vibrate loose just a little, the clamps literally fall to the floor of the bed. Murphy's Law, if it can happen, it will happen... They say it never has, but I can't in good conciousness leave my driveway with it on. From there, because I made sure the clamps were tight, the rails are slightly past vertical (even with the angle shims that were attached), so there are resulting alignment problems with the top, and it has to be worked to open, fold, unfold, and close. And I wouldn't dare loosen the nuts on the aforementioned rail clamps to get it better aligned... The little pad strips that are included are imo insufficient to protect the back window and third brake light (it's cheap, and doesn't cover the contact points adequately or at all). I'd feel compelled to get a large piece of foam to cover the back window and strap it somehow to the cover. And btw, it does block most of the third brake light. The prop rods in and of themselves are ok, but the attachment/adjustment point sucks. Once put into position and tightened, it will move if you apply some pressure to it. How tight do you have to get it before it strips out...? This is something that would be used repeatedly, No intention to be negative here as I'd prefer to be writing a positive review. But if I'm buying something at this price, I certainly do not want to be having to figure out how to modify it to make it safe and secure, or to prop it up so that it works as advertised, and doesn't break out my back window, all on DAY ONE... ... show more

This cover was for my '22 F350 6.75' box. I am completely amazed by this. Amazing fit, seems very durable. It keeps everything in the bed secure, and seems to seal the water out. I would make this purchase again over any of the canvas or other kinds. It should be a good investment and should stand the test of time. ... show more
