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.

Looks Great!

Great product easy to install. I appreciated the quality and appearance of the cover. However, there were some water leakage that I will be fixing later but overall I like the cover, and how solid it looks and feels. Expensive but for the fit and look, well wort the price.

Great cover, pricey but worth every penny
Style: Revolver X4s
I researched covers for my Ridgeline extensively and settled on a roll-up BAK. Assembly was straight forward, directions/YT video provided me with what I needed to install it and that took me a few hours. Low profile, very secure, looks great and the only leaks I have right now are in the two back corners that don't impact anything I would have in the back. Plan on eliminating those when I have some free time. Well done and highly recommended. It isn't cheap, but in this case you get what you pay for. ... show more

Ridgeline's Don't Have the Required Drain Holes. Leaky Tonneau Cover. Poor Quality.

Review Image by Jacob Keyes Jacob Keyes
I purchased a BakFlip MX4 for my 2021 Honda Ridgeline. The first thing you will notice upon opening the box is "Made In USA" writing so I was all excited thinking this thing was going to be top quality. However, the cheap quality of the panels themselves was my first disappointment. They are not a hard, durable material with a rich black pigment which I was expecting - they are more of a flimsy styrofoam with a porous dry crackle finish. The install was straightforward although I was constantly thinking to myself, this doesn't seem like it's watertight at all. The design for the prop sticks that hold it open when folded seem to have been designed on a Friday afternoon before a holiday. All of the fasteners and seals are standard China whitebox; several pieces were broke and just plain fell off during the install; Bak Industries is sending me the replacements. There are these drain tubs that are supposed to go into drain holes which I have confirmed the Ridgeline does not have. Saying this tonneau fits a Ridgeline is a questionable statement with that as fact. I called support at Bak Industries and was told to run those into plastic bottles and empty them when they are full; I assure you that is not a joke and 100% truth. We had a good rain storm last night and sure enough the bed is full of water. It leaked it from the front seal, the side seals, and of course the drain tubes. I've ordered a tube of permatex black silicone and unfortunately will have to try and seal up this brand new tonneau cover on a new truck. I have had cheap tonneau covers in the past on other trucks and never really had a problem with leaking. This product is not something I would purchase again or recommend to family and friends. ... show more

Be prepared to make alterations
Style: BAKFlip MX4
Installation on 2019 Honda Ridgeline. Similar to other reviews I have read i ran into many problems during installation. The rail mounting brackets on the back end had to be cut out somthey would allow the mounting holes to line up ( i read on a different review that this would need to be done). You would think Bak flip would have corrected this by now. After that the rails went on smoothly. The next big issue was the cover was assembled too wide for the rails. The locking tab mechanism was mounted too far out and would not clea the rails when dropping the panels into position. Panels would not close properly without force and were almost impossible to open. I had to unscrew all six mounting mechanisms and slide them in so they would clear the rails. Six new holes had to be drilled for each mechanism. Iafter these adjustments the panels opened and clesed smoothly, similar to the cover I had on my 10' ridgeline. Lastly the last panel does not close well. The side material on the panel catches on the rails. Rails need to be moved out some. I do not have a fix for this yet but will try to put a shim im the mounting plate so the rails widen some. I only need a couple mm so i think this will work. As far as overall fit it is much worse than my old back flip cover on my 10'. That assembled and fit like a dream. I question if the seal will work and keep water out. Oh, lastly the water drain tubes at the front do not fit into the drain holes in the bed. Havn't figured out what top do with this yet. After all these modifications I have a workable cover and will probably be happy wih it but if i didnt have the proper tools and work bench i would be very unhappy with an unusable cover. Buyer beware. ... show more

Cover is very good. Customer service is not.
Style: BAKFlip MX4
The BakFlip truck bed cover is a solid choice for my Honda Ridgeline. Its sturdy construction holds up well against everyday use and weather, while the folding design provides convenient access to the truck bed when needed. The cover looks great, adding both style and function. However, installation requires careful alignment, and while it does a good job keeping out rain, some minor leaks may occur in heavy downpours. Overall, it’s a reliable. I did have issues with the company customer service team. Not very responsive. ... show more

Fit perfectly, looks great

Installed in just a few hours. Good directions. Took my time and added a few additional sealing tape strips. Pretty much water tight for rain. Just a little leakage at the jet carwash. I like that the cover is almost flat and that it is secure.
