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.

    • Service On Next Level - Item Was As Expected - Solid Fit on 2023 Plat-Tundra
Style: BAKFlip MX4 Size: 5' 7" Bed
First of all I ordered this on a Saturday night around 7PM. Delivery said Wednesday which was great. Upon checking out the delivery moved up to Sunday. Thats right, next day. Going through the process in once again confirmed this date at checkout. Emails and text also confirmed next day delivery. Like promised, the next day it showed up at 1PM. Driver unloaded it in my garage and was super professional. Item was flawless and free from damage. Install took 20 minutes max. Helped to watch a quick video online related to the install first. Item fit like a glove as most have said online. The only issue I had was related to the front cargo bracket which Toyota didnt center correctly. Truck bed is dry and secure. Amazon is amazing on this item. Saved a couple of hundred bucks on the price and got service above what anyone could offer. It wasnt even close. So happy I made the call. 18 hour delivery is something no one else can touch folks! ... show more

    • Easy install and simple to use
Style: BAKFlip MX4 Size: 5' 7" Bed
Easy to install and even easiest to use. I installed it on my 2025 Tundra in a couple of hours. That much time was not required, but it was my first attempt. It fits great it is flush and allows me to use the entire bed when I fully retract it. It came highly recommended by two people I trust..

Style: BAKFlip MX4 Size: 5' 7" Bed
Bought my 2023 Tundra seven days before leaving on a planned camping trailer trip. Ordered this cover the very same day and it came in time to install with two days to spare. Small problem though: Although the shipping box was entirely un-damaged, the very first piece that I came to upon opening the box didn't look right. It was the LH side-rail, the piece that all of the locking tabs engage. One end of this one piece is a section of the extruded aluminum channel with about 80mm left after the rest has been cut away, forming a flat, overlapping projection that lives in the vicinity of the juncture of the bed side and front. This LH piece had that 80mm or so of flat aluminum bent at more than a 90° angle. The RH side piece was perfectly flat and true. I knew that I could probably straighten out that bent end, maybe without actually breaking it off altogether but you know what it's like to bend, and re-bend thin aluminum. You can usually bend it once, even sometimes fairly extremely, but the odds of straightening it back out without seriously compromising the strength of the piece aren't great. I was able to get it fairly straight by securing one end of the piece with a real big crescent wrench while gently working with wide jawed pair of parallel pliers. When it was straight there were definitely small cracks faintly showing up on the surfaces but it was solid enough. After taking a lot of pictures to document what I'd found and done, I continued to install the cover. What a joy. Except for the fact that some of the pieces were really heavy and somewhat awkward for me to do by myself I got it done in about 90 minutes. I hadn't done enough research prior to starting this to realize that the very first instruction to "remove the existing inside bed rails, if present" was not a catastrophe. Oh crap, I thought, one of the things I've always loved about my two previous Toyota pickups was the fact that this really cool rail system was built in. I needn't have worried, as the rails are re-installed in a slightly lower position using some really nicely made bits of engineering. The hardest part of the whole installation for me was trying to get the drain tubes to fit in the existing holes in the Tundra's bed. This cover, in use, is fantastic. It sits very low, hardly visible above the sides of the bed at all. It opens, closes, folds up into several different useful configurations and when the truck is locked, the tailgate is too so there is no really easy way to simply pop it open. I wouldn't leave wads of cash in it out on the street but for camping, shopping and general outdoors use it is the bomb. Almost entirely dry inside even during and after monsoon-type rainstorms we've had here on the East coast recently. I called the manufacturer and after a brief description of what had happened I sent them some photos and in a week they delivered a big package with both LH and RH side rails. Great customer service. ... show more

    • Very good - but not perfect.
Style: BAKFlip MX4 Size: 5' 7" Bed
Do yourself a favor and throw the instructions away before you start assembly. They are basically useless and YouTube has some great instructional videos. Once I got that figured out, install was relatively easy with a second pair of hands. Cover snaps in easily and is flush with bed rails. It looks really slick. Access to the bed is easy and can be done from the side without climbing into the bed. The drain hoses are a nice touch and after testing out a 30 min drive in moderate rain, there was no noticeable water to be found. It’s nice that the rail system can still be in tact after the install as well The buckles that you use to strap in the cover panels when it’s folded are not high quality. They are a bit of a redundancy anyways , but still a little better quality expected on something this pricey. The tailgate needs a seal as I’m sure at some point some moisture/dirt will find its way in there. Overall - good but not perfect. 4 stars for me ... show more
