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.

    • Tonneau Cover
Style: BAKFlip MX4 Size: 5' 1" Bed
Nice product but the installation instructions aren't worth the paper they are printed on. If you buy one throw away the install paperwork and go to youtube. If you can understand the directions they send install will take 2-3 hours as it took me. Finally looked at youtube to finish the install. The youtube video that someone posted will take you 30 minutes to install. Even their online product review card that they include with the packaging doesn't let you give feed back to them. All it takes you to is product sales. Too bad they ruined the install experience for me. I would recommend the cover. But YOUTUBE THE INSTALL. ... show more

    • Just what he needed
Style: Revolver X4s Size: 6' 1" Bed
Review Image by Amber Amber
My brother in law gave us his old car when he bought his truck, and as a thanks, we bought this for his new truck. Easy installation! He and my husband had it completely installed in just over an hour. The instructions were perfect and they had no trouble. It looks great! It’s durable and secure and does exactly what he needed… keep his bicycle or other gear out of sight and secure while he runs in to the store to grab lunch supplies, etc.. Apparently a tiny bit of water leaks into the bed, but other than that is great. ... show more

    • Ford Ranger - Fits well
Style: BAKFlip MX4 Size: 5' 1" Bed
I am very satisfied with the end product. It looks nice and performs well. Installation goes much smoother with a helper (IMO helper is required and recommended in the instructions). I questioned the the clamps for the rails, but once installed they seem secure. I needed a tap M8x1.25 (found at Northern tool) to clean the threads in my truck bed due to a spray in bedliner. I've used it in the fully open position and the 3/4 open position without any problems. Fully closed is secure. ... show more

    • Beautifully designed yet questionably flawed
Style: Revolver X4s Size: 5' 1" Bed
I was in the market for a retractable tonneau cover but had to go a different route due to the size of the canisters that would not have allowed me to fit my kayak's nose under which meant that I would've lost 1 foot of length, protruding the kayak further out (which I wanted to avoid given how short a Ranger's 5' bed is). I knew I wanted a hard cover but did not particularly like folding covers because of how much space they took when folded up, pretty much covering the entire rear view window. I disliked the idea of not being able to see behind me in order to keep an eye on my cargo or while reversing with the tailgate down. The Revolver X4S's design is pretty much the solve for my situation. Hard cover, gives me full bed access, will not block my view, and no large canister to worry about. Being that this was my first tonneau cover install ever, I made sure to watch as many install videos as possible. As prepared as I was though, there were definitely some hiccups along the way. There were vehicle specific brackets with no install directions that caused considerable confusion. I had to install it without them to then realize I definitely needed them in order to get the fitment correct. After uninstalling the cover and finally solving what position the brackets needed to be in, installation then became quite simple and certainly doable in a span of 30-40 mins. The bulk of the time was really spent on tightening the bed brackets onto the sidewall. Since Ford Rangers (or at least mine) have short smooth sidewalls, it was an aggravating process because of how easy it is for the brackets to slip off regardless of the teeth. After a total 2.5hrs with help, the fitment was where it needed to be. Now for the issues. As other reviews mention, there are quality control issues. Only after finishing the install did I notice these things. My cover is not completely flat. It has a large groove/bump towards the front (same as another review pictured). While the bulge does not interfere with the closing or create any side gap, it IS extremely noticeable visually. So if you're OCD about it, it may give you a problem. For me, I could live with it but I mean, at this price point given that I could have purchased a retractable aluminum for less- this shouldn't be acceptable. It also arrived with a broken corner cap which leads me to the next issue - this is NOT as secure as most other covers. I don't want to elaborate but revealing the closing mechanism is very simple if known. While most covers are not 100% theft-proof, they should act as a deterrent. So being that it would only take seconds for someone to open this cover if they were aware of this is concerning to say the least. Why couldn't this piece have been made of metal and be permanently fixed? I'm not sure. The ends of the rails are also VERY sharp so make sure to shave/file them down a bit. Overall, it looks and feels great despite the issues above. I've emailed the company for replacement corner caps. I don't expect to keep valuable items in the bed but it helps keep things out of view and the elements. Best part is I did not sacrifice much space for it. Time will tell how well this holds up. ... show more

    • No hardware or parts to install.
Style: BAKFlip MX4 Size: 5' 1" Bed
I received the cover which looks great and feels sturdy. I did not receive any hardware to install it nor were there any instructions in the box. I’ve messaged the manufacturer and I am awaiting a response. If I receive the parts I’ll post an updated review: if not I’ll post that and return this.

Be prepared to be disappointed with install. My package was missing the spacers that are needed to level rails. Contacted manufacturer. They were helpful, but sent new kit and the spacers were missing again. Even with spacers I am not convinced the rails will sit where they need to. Seems like product is not really a match for the ford ranger 2019. Reinstalled 3 times and still can't get it right ... show more

    • Great cover, great customer service
Style: BAKFlip MX4 Size: 5' 1" Bed
Great cover, great customer service. I was a little confused with the directions for the installation on my 2019 Ford ranger. After a call to customer service they immediately solved some problems that i had . When the cover is folded back towards the cab it does need some thick bumpers so that the cover will not hit the cargo light on my truck. Other than that I think it’s a great value and a great cover. The customer service from the company was excellent with any concerns I had, I would definitely buy from them again. ... show more

The first time it rained it leaked a little in the corners but after wearing in for a month it doesn't seem to leak anymore. Lost a small corner trim plastic piece, maybe from somebody trying to open it? Emailed support and they just sent me a new one. No trouble since. Its pricy but I would buy one again. ... show more
