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.

It is a great tonneau cover It looks great and was easy to install once I figured out what was going on. It’s not as strong as a CyberTruck tonneau but does support a surprising amount of weight. I like the way it folds out of the way for loading landscape materials with a bucket loader then folds back over the load so the highway speeds don’t blow the material out. And there are no rail troughs to get filled with the material. It isn’t water tight but pretty close to it. ... show more

    • better than expected
This BAKFlip MX4 replaces a broken rolltop cover I had. I installed this with a little help for alignment, and it was easy to do! I put this on a 2002 Chevy Silverado extended cap Z71 with the 6.5 foot bed. It seems durable, looks great and the best part is my wife, who is 5 feet tall was able to open it completely without getting in the bed of the truck. I was impressed, they really put some thought into how this cover should work to be useful and user friendly. In my opinion this was a win all day long; not to mention I think it makes my truck look great!!! The only downside was the instructions, in one hart was a little confusing where they were discussing the use of wedges; they are included ads are thick rubber strips; not what I expected but when installed are perfect! ... show more

I love the look and function of this tonneau cover. Easy install with my son’s help. This is the second MX4 I’ve owned. After having the first with the full functionality of the bed, I knew what I wanted. I wouldn’t own any other cover.

    • Very nice looking unit!
The directions were a little difficult to follow, but after re-reading a couple of times figured out what to do. The paperwork said these would fit my truck even with caps on the truck bed rails, but they did not. So had to spend a day removing part of the plastic rail caps. After that fitting the equipment took some doing, but the end result is great. It would be a nice feature if the unit came with some kind of locking mechanism, as my truck isn't as new as some and the tailgate doesn't lock, so will need to find a way to remedy that. Just recently got it installed, but seems to work nicely. Hoping for a long life! ... show more

Quick delivery. Ordered on a Sunday, delivered on Tuesday. Arrive undamaged and everything in the box in great shape. You can do it solo but I recommend an extra pair of hands. ☆☆☆Note☆☆☆ Be sure to read the extra sheet of instructions for guidance on shims and spacers. Most trucks will need them. If they do. They are easy to add and are included just make sure you do them when called for. Otherwise the cover won't fit right and you will have to remove and replicate effort. Sound like I have experienced this? Yes I did. I also recommend watching YouTube videos to supplement the written instructions. All in all, very happy with product and very happy with the company that sold it to me. ... show more
