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.

    • Quality cover
Style: MX4: America’s Top Seller
I got this for my 2024 Maverick Lariat. Installation was straight-forward. It has worked beautifully for months now. Some folks expect their bed covers to be watertight, but I'm not one of them. When I can see light along the edges of a closed tailgate it seems a bit much to expect the cover to be watertight. This cover does fit very well and the seals around the perimeter do lead me to believe that it's doing a good job of keeping rainwater out. I have yet to see any water in the bed of my truck. Everyday use is easy. The one hand operation for opening each section works very well. When I want open access to the whole bed, the provisions for attaching the sections up against the back window are quick and easy. When it's time to close up, it's an easy process of flopping each section over. Since they are self latching no other effort is required. I'm one of those people who will choose function over form every time, but in the case of this cover I don't have to. With its near flush mounting and aluminum finish it looks terrific on my truck. It's added value, utility and good aesthetics to my truck. ... show more

    • The last panel flips up by design

It takes a bit of research to figure out what style of bed cover meets your needs. I read a gazillion reviews that dwell on some very small details. I had already decided I wanted a solid, folding bed cover because I frequently fill the entire bed with yard trimmings to haul to the yard waste recycler. I also use the cover to provide security for luggage. Here's the deal: Many of the solid folding bed covers do not have a way to fold the section closest to the cab into a vertical position. That leaves a pretty big area of the bed that is less useful for hauling large loads. Reading the product descriptions of many other bed covers will offer you little insight about this feature. I would not have known about it without talking to my buddy who paid $1400 for a virtually identical cover on his new F150. We had to use the feature hauling stuff on his truck and it convinced me. Beyond that one key feature I'm most impressed with the light weight yet durable construction of the panels. The panels are finished on both sides. Each panel has a latch, so if you want to haul a load with one or two panels folded over, the next panel will still be latched. Speaking of latching, the first panel will not unlatch unless the tail gate is open. My tail gate locks, so it's a pretty secure system. I sleep better in hotels knowing there is at least some level of security. Installation was not difficult. I did it by myself, but was not assisted by the instructions. I was referred to a web site that offered a video that was in no way similar to the attachment process for my model. The biggest issue that you need to figure out is the six aluminum clamps that attach the frame to the bed of the truck. Look carefully as there are several ways to configure them. I have no regrets on this purchase and expect the BakFlip to last many happy years! ... show more

    • Compared a lot of these covers and found this to be the best.
Style: MX4: America’s Top Seller
Live in CA, wanted to avoid people tearing open a soft top to see what’s inside, did not want a retractable because there’s not a lot of bed in the first place and didn’t want to lose any more space. So, trifold was the way to go. I wanted a well made one that did not occlude the theirs light when flipped up. It was between this one and another cheaper one. But that one had huge clamps to hold the cover down. Those clamps would get into the way of the sliding tie downs in the bed. So, this was the winner. Easy install, looks great and makes the bed usable for running about Town buying Christmas presents. Not a water proof as I would have liked. I’m trying to track down the leak but haven’t found it yet. It’s a small leak so no biggie. ... show more

    • This is the best design if looking for a tri-fold hard top
Style: MX4: America’s Top Seller
Took a little longer than advertised due to my mobility issues but installed easily and is very functional. Adds that extra layer of protection from prying eyes. Works great with the locking tail-gate. This design beats the other hard tops. A true tri-fold hard top that opens all the way against the cab when needed. This was a good point since this a small truck bed in the first place you want all the open room you can get for tall or larger items. Many other hard covers don't open fully from what I've seen. ... show more

    • Good cover with minor flaws.
Style: MX4: America’s Top Seller
I purchased this for a 2024 Maverick with the factory spray in bed liner. It's sturdy and well built. I had a hard time getting the clamps for the bed rails to lock in correctly and had to take the rails off and reset them. Once I did that the cover clicked in to place. The packing for shipping is very good. My initial impression is that the quality and materials are good. It clearly won't be completely waterproof, but I don't expect it to be. I am taking off one star, though, because details matter to me. As mentioned by others below, the two sets of holes drilled through the aluminum frame are poorly done. When I took the tape off there were aluminum shavings in the tape. The holes themselves are not the kind of smooth, clean holes I would expect. They work and they are in the right place, but they looked like someone was trying to get every dime out of a drill bit that needed to be changed out long ago. The cover doesn't come with printed directions. There is a QR code and a URL that takes you to their website. I couldn't find any kind of printed or text directions. There are videos for a few different installs. When I tried to launch one, I got a message that it wouldn't play because I hadn't accepted the privacy policy. It let me read the policy but I never saw an accept button. Thankfully the same videos are on YouTube and you can watch them without any issues. Still, being out in the sun and trying to step through a video on my tablet made the install harder than it needed to be. I'm still happy that I bought this and expect it to meet my needs. But it could have been a five-star review except for a couple of minor issues. ... show more

    • Great product, but...
Style: MX4: America’s Top Seller
This is a solid and well-designed cover. That said, the installation instructions are not included. You have to scan a QR code to get tiny, unreadable instructions on your phone. There are videos but only of you accept all of their cookies. I did but then discovered there was no video for my Maverick, only for other trucks. I figured it out on my own. Lastly, the 3 stick on foam blocks to protect my back window: when I peeled the paper backing off to apply them the adhesive stayed on the paper. Useless. I'm requesting replacements. If that goes well, I'll give them 4 stars. ... show more

Extremely functional, easy to install. Fit my Maverick perfectly. Heavy duty, probably could stand on it. Very well worth the investment. Had many compliments on it.

    • Excellent design and materials. Good fit once installed (but no instructions for Ford Maverick).
Style: MX4: America’s Top Seller
There (currently) are no videos posted by RealTruck that describe installation of this cover on the Ford Maverick. No printed instructions are provided in the box; all information is online only. By watching their videos on other vehicle installations (e.g. the F-150 and Ranger) I was able to figure out how to do it on my Maverick, but it took additional time. Once done, however, this is a very nice cover ... excellent design, materials and fit ... and it's easy to use. ... show more
