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.

  • Perfect product! easy to install! Beautiful addition to my 2008 Dodge Ram 1500.
Style: BAKFlip MX4 Size: 6' 4" Bed
I am so glad that I made this $1039.00 purchase. There are other, cheaper tonneau covers available on Amazon, but I received input from a professional installer that this was the top-of-the-line cover and I believed it and made the purchase. I am so glad I spent the extra money and got this BAKFlip MX4 cover for my 2008 Dodge Ram 1500. It was a perfect fit, easy to install, is really beautiful, totally functional, and is the perfect cover. I DO RECOMMEND this product for anyone who wants a beautiful, secure, water-tight, easily-accessible, easy-to-install, and sturdy, five-year warranty for a cover. One may spend only a couple hundred dollars on a tonneau cover but one really does get what one pays for. This is the tonneau cover for the discerning pickup truck owner. You will not be disappointed with this purchase even if the initial price is a choking point. It is worth the money!!! ... show more

  • Great way to secure your truck bed
Style: Revolver X4s Size: 6' 4" Bed
I was looking for a way to secure the bed of a 2017 RAM 1500. Did quite a bit of research and settled on this when I saw the neighbor down the street with one rolled up on his truck. The price was right and shipping was quick. Construction is solid and all parts arrived and fit my truck perfectly. Installation was a breeze and I'm not exactly what most people would consider handy with tools. So far, it's kept the truck bed bone dry thru heavy thunderstorms even when going down the interstate. Looks good too. I haven't had it long enough to rate it on durability but might come back in a couple of years and update. My goal with this purchase was to secure the truck bed so I could store items in there without fear of theft. Mission accomplished. ... show more

  • Nice Product - No Regrets
Style: BAKFlip MX4 Size: 6' 4" Bed
Overall, a nice product and I would buy again. As for the question / rating about water resistance - I can't speak to that as of yet, since it is a new install and hasn't been water tested. As for the rest - the installation is fairly simple and the cover is strong and robust. Some things to watch: * Make sure to use the shims if the rails sit at a slight angle, due to some curvature of the bed rails - if they sit at a slight angle, you may have issues with the seal properly contacting the tailgate. There is a supplemental sheet that includes shims and tells you how to use them. Your truck may or may not need them. * They say to install the bulkhead seal as one of the first steps. The install instructions don't clearly specify if the seal should be at the front, rear, or centered on the bulkhead (although the video does say to place it on the edge closes to the rear). I would wait and do this at a later step - for my truck, the bulkhead seal needed to be just a little bit away from the rear edge - meaning I had to remove it and reinstall it (this impacts the adhesive quality!). Its best to fit the cover first, then determine the exact location of the seal. Once the cover is properly fitted and in place, it will be very obvious where the seal needs to be - then you can easily lift off the cover (before securing it) and add the seal. Not having the seal does impact the general install and fitment of the cover - you just need to add the seal before bolting the cover down at the front. * Keep in mind - you don't need the bulkhead seal if you have a drop in bed liner that covers the bulkhead. If the bulkhead surface is painted metal - you need the seal. * While installing the rails, start at the middle (place the first clamp in the middle). I used a vice-grips to initially hold the rail in place - I didn't have a helper and this made it easy for me to keep the rail in place before installing the first clamp. * On the rear panel, I had an issue that required me to remove the latches on both sides of the cover / rear panel, reposition, and reinstall with the sheet metal screws (I used my screw gun for this - but be careful not to strip and over-tighten). The latches were installed with some adjustment capability, but not enough. The latches were sticking out too far and hitting the rails! At first I thought that my rails weren't all the way in - I confirmed this wasn't the issue. A look at the latches on the rear panel compared to the latches on the center latching panel clearly depicted my issue - the latches on the center panel (exact same type of latches) were further in, allowing clearance from the rail. The latches on the rear panel were clearly misadjusted and sticking out too far towards the rails. Again, I didn't have enough adjustment on the latches to compensate. This was fairly simple to do - took an extra 5 or 10 minutes (after figuring out the issue). But this shouldn't have been necessary. If yours sticks - check the rails before moving any latches. You want to make sure the rails are properly seated - otherwise they can interfere with the panels. Overall, nice product and nice look! Hopefully it does a good job repelling water - I have heard feedback both ways. I didn't want to rate that particular function as I haven't tested it. Overall, it took less than an hour to install - even with the minor latch issue. I installed myself without a helper. ... show more

  • BAK company stands by there products!
Style: BAKFlip G2 Size: 5' 7" Bed
This cover is quite expensive but still competitive with other brands out there. I went with BAK cause reviews were quite solid. I found and open box for close to 60% off and took a chance. It was still prime so if it was missing parts or damaged I felt ok with the gamble. I installed it on my 2016 Ram Rebel. Like others have said. WATCH THE VIDEO!! installation instructions aren’t the best especially if your not a bit mechanically inclined. All that said, installation after watching video was straight forward. Very nice looking and quite sound. I was anxious to install and get my tools secure so I did this at 11 pm and it took about an hour by myself. I was rushing and forgot to install the drain cups. (After 2 very heavy thundershowers, very little water got in) So needles to say I installed them the following weekend. I was missing the two prop rods and the two stow clips for the rods. I contacted BAK direct and all I had to do was provide a screenshot of my Amazon receipt and my home address. They expedited the parts with ZERO HASSLE! The lady was super kind and professional. She was adamant about contacting them in the future if there were any issues with my cover. Fast forward 4 days and not only did I get the two prop rods, but they sent me the entire installation kit! They could have easily sent me the parts separately. They didn’t skimp out. I now have extra gaskets and seals and clips for future! ... show more
