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.

    • Installation instructions need to be revised
Style: BAKFlip MX4 Size: 6' 7" Bed
Well made -- looks great - installation is easy, though instructions need to be redone. It is very difficult to get the clamp in the proper position against the bed rail and the instruction say to 'get a second set of hands' to do the job. The MUCH easier option is to simply remove the one screw and cap on the tail-gate end of the rail and slide the clamps into the groove and down the rail into position. I eventually figured this out after struggling with trying to get the clamps into the proper position and for almost an hour and worrying about bending the rail track, when it took 5 minutes after removing the caps. ... show more

    • Love it
Style: BAKFlip MX4 Size: 5' 7" Bed
Love this thing. I shoulda bought one years ago for my tundra. Easy to install. Works great. And only a little bit of water gets in it. I was quite suprised how much rain it kept out. Not 100% waterproof , but I was suprised how good.

    • Superior Cover

Hello, I purchase the bakflip mx4 cover approximately a month ago. The cover is extremely well-made, the drain lines work perfectly and the cover has a extremely low profile fit and finish. Installation was relatively simple with a few basic tools, the only thing that was remotely challenging was finding a 7/8" drill bit to drill through the plastic plugs for the drain lines. I would certainly not hesitate to purchase this cover again, it's extremely well-made, lightweight, and completely folds flat up against the rear window. This was an excellent purchase. ... show more

For the most part this is a great cover. There are, however, a couple of issues that I’ve noticed that aren’t major but warrants mentioning. The pros: First, the cover was easy to assemble. Working alone it took me between 45 minutes to an hour to install the rails and cover. Another thing is the cover is that it simply looks great. I’ve had other truck owners compliment me on how good it looks. Pretty much all the compliments have been from people that currently have the soft covers. Also, I have no rattling or noise when I’m driving; it fits my bed like a glove. The cons: The tube mounted underneath the cover that guides the wire that releases cover has popped out. I plan to go to the hardware store a get a same screw to secure it. At times the rods that act as a prop when the cover is fully opened will fall from the little holders when they’re not in use. This is not to be confused with them coming off while they are propping up the cover. They are very secure. Another issue is that I’ve had to fish a screw or two from the bed an resecure them to the underside of the cover. Lastly, the cover in not completely waterproof. This wasn’t a deal breaker because going in I knew that it was a possibility that it wouldn’t be waterproof since I’ve read mixed reviews regarding this issue. The manufacturer does not guarantee the product to be waterproof, however, some people have had success in the area. It has been my experience that rain will permeate the edges of the cover especially when it’s sitting in the rain. When driving through rain, the rain washes right off before it seeps down through the cover. The amount of water isn’t all that bad; if I had to guess I would say it’s about the equivalent of having two cups of water splashed in the bed and almost always just near the edges so I try to put items that need to stay dry towards the center. Overall, it’s a really nice cover and in the seven or so months I’ve owned it the minor issues I’ve had with the product is far outweighed by the utility, look, and convenience of having the BAKFlip. ... show more

    • A great bed cover
Style: BAKFlip MX4 Size: 5' 7" Bed
This fills my requirement for a sturdy bed cover to protect the items in my bed. This brand is a little expensive. I bought a return with a damaged box. It was complete, and easy to install. It has worked well for me. I keep a couple totes with extra supplies in my bed, and this provides good security and protection for that equipment. It also makes for secure, relatively dry storage for luggage, etc. on longer trips. ... show more

    • The back of the truck looks sexy

I highly recommend this product. I know it's expensive but you will be happy with the look of your truck after it is installed. It wasn't that hard to install, also I like that it's strong and it's going to keep thieves out of my bed.,

The media could not be loaded. Had this for a week. It leaks to me where the center does a double fold when you fold it up. So when it’s down it doesn’t seal good. I have more clamps on there way because the three per side that they provide isn’t enough. This shell has already shifted on me and everytime you let a section down it feels like it’s going to come off the tracks. Wish I could get my money back. 1100 dollars doesn’t grow on trees ... show more

    • Easy install, nice low profile look, almost waterproof
Style: BAKFlip MX4 Size: 5' 7" Bed
Great cover, easy to install, great look. It keeps 99% of rain out, however heavy downpours will leave some water under the cover. If you have something that absolutely can’t get wet, I wouldn’t recommend. Also as some others have noted it is susceptible to hail damage. I had nickel sized hail a week after I installed it and I have 9 faint dents. I have had 3 people come up to me in parking lots and ask me about the cover because they like the look, asking about the brand. ... show more
