Description

The BAKFlip MX4 was the first matte-finished, hard folding cover to market, becoming America’s 1 Selling Hard Folding Cover in just a few years. Simply put, the MX4 just looks better than other covers. Its sleek no-profile appearance allows you to maintain the appearance of your truck, while enabling you to securely stow cargo in the bed. The MX4’s pioneering, textured matte- finish adds a premium look and feel while also protecting against UV damage, annoying finger print marks, and scratches. MX4 has everything you expect from a premium cover. The engineers at BAK Industries fine-tuned even the smallest elements of the cover, down to adding cab corner caps and rail-end cap, to extending a matte-finish throughout the cover’s side rails, clamps, and elevator bolts. The MX4’s integrated buckle system and automatic latching mechanism allows you to drive with the cover partially or fully opened without covering the 3rd brake light. For 100% bed access, simply unlock the cover from either side via its pull latches and fold the cover all the way up against the cab. From there, you can prop the cover in place by tightening two rods into the underside of the panel. For enhanced durability, the MX4 also features pre-molded, shock-absorbent bumpers on either side of the panel, protecting the folded panels from hitting the cover during turbulent driving. Rain or shine, the MX4 provides confident cargo storage that’s complete with dual drain tubes to divert water away from the truck bed, as well as full perimeter seals to help protect against water intrusion. Finally, the MX4 can hold up to 400lbs of evenly distributed weight and is backed by a 5-year, hassle-free warranty. BAKFlip MX4 is proudly made in the USA with globally sourced materials with a US-based support team.

  • Pricey, but really nice.
Pattern Name: Revolver X4s | Hard Rolling Size: 5' 7" Bed
Pretty straightforward install. Helps to have a second person but not absolutely necessary. Very secure once latched down with gate shut. Would likely take a pry bar to defeat it and not just a slice with a pocketknife. Sits, and stays, nice and flat, until you roll it up. Been through the touch-free car wash a few times and very minimal water intrusion, mostly rear corners along the gate, which then drains right out. ... show more

  • Good fit, easy install
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
I was hesitant to buy this model because the description states “w/o cargo channel system” so I wasn’t sure if it was compatible with the stock bed rails on the ‘24 Tundra. It came with hardware to fit in the rails, did not have to remove them. Works great!

  • Quality, but not without issues
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
First the good. This is a quality piece that once I figured out the installation looks great and performs as it should. Now the bad, and my reason for only 4 stars. I have a 2024 Toyota Tundra. On the companies website, they advise for my model number that the factory tie down racks will be relocated lower and still usable. I watched the factory instal video for my truck on YouTube which also showed this. However, Amazon stated in the listing that the factory rail system could not be used after installation. I would like to use the rail system if possible but some previous reviews advised that they received the kit that relocated the rail system while others advised they did not. Both are the same model number by the way. I even chatted with Katie C. at the factory who advised the Tundra rail system would be relocated with my kit. When the cover arrived I followed the video installation and removed my factory rails, only to find after some confusion that my kit uses the Tundra rail system for attaching the cover, therefore rendering the Tundra rail system unusable. Not a deal breaker but very upsetting after trying to confirm with the factory. Also, you have to mix and match some of the hardware to make the kit work on my Tundra. Included in the cover was weatherstripping for the front of the bed that was not even included in the written instructions but called for in the instal video. I removed it after installation because it caused the front of the cover to lift. It looks better without and still has a bunch of rubber material for weather resistance. Looks good now but was a pain to figure out with the conflicting information. This coming from someone who is mechanically inclined. ... show more

  • Easy to install. Fit great
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
I decided to buy this based on the YouTube video named "2023 Toyota Tundra Bed Cover BAKFLIP MX4" with the fit. Ensuring the rail system is still used (it moves down but is still very usable). Price is a little high but it is a quality product. The fit is good besides the section near the tailgate. Has a few gaps there. Its rained a few times here and no problem. ... show more

  • Great product, HORRIBLE CUSTOMER SERVICE
Pattern Name: Revolver X4s | Hard Rolling Size: 5' 7" Bed
The owner of BAK is RealTruck.com and they have been horrible to deal with. They know that the corner clips on this product are awful so when you order replacements, they send you 3-4 sets to cover for the next few times they break. One of my rails is defective and I sent them a video of it. They responded and asked for my invoice which I provided, and they allegedly sent me a replacement rail 15 days ago and it still hasn't arrived. You can expect about a week between your correspondence to them and their reply to you. If my replacement rail doesn't arrive soon I will be opening a case with Amazon. I initially reached out to Amazon for replacements of defective items and they offered to ship out a full replacement for me to harvest the parts I needed to make my item whole. I declined and decided to go through RealTruck to give them an opportunity to resolve the issue and now I'm seriously regretting it. This is exactly why I bought the product through Amazon instead of RealTruck, because if I had purchased through them directly, I would have been SOL. I hope I never have to contact them again. ... show more

  • Great buy for your truck.
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
We got this for my 2023 Tundra and it was pretty easy to install. We did it in less than 2 hours. My husband watched the YouTube video on how to install. It fits perfectly and easy to open. Saved $400 installing yourself. I highly recommend the Bakflip.

  • Really like this cover
Pattern Name: Revolver X4s | Hard Rolling Size: 6' 7" Bed
The BAK Revolver 4S installed relatively easily on my '23 Tundra 6.5' bed. The shipping box is quite heavy though. It looks secure though no cover is truly secure. It does a good job of minimizing water in the bed but if you drive on dusty roads, the cover creates a vacuum space that sucks dust in past the tailgate. This is not the cover's fault. The tailgate needs a seal. There were a couple sharp edges at the rear of the side rails. I covered these with black tape. Otherwise, I thought the quality of the cover was appropriate to the price paid. I don't like the strap arrangement for travelling with the cover rolled up. It's a bit of a pain to get the straps plugged in and tightened. It does work though. The install instructions were a bit vague - could use an English major's eyes. ... show more

  • Like it, but
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
It came with none of the hardware, but I called and it was sent out in a couple days. There is a pretty significant dent on the cover and I’m still deciding if I will get it replaced. The rub rails will not stay stuck on. The install was easy and it looks good and functions great.
