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. .

  • Easy to install. Impressed with the fit on my F250.
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed
Really nice fit. Easy to install. I like that it cannot be opened without opening the tailgate. If your tailgate locks, the cover will be secure. No cover is completely water tight. Have not tested it with a wash or rain yet but judging from how it looks, I bet this is one of the best covers when it comes to keeping your cargo dry. Looks great on the truck. Very happy with my purchase. Plus saved $100 by purchasing on Amazon vs one of the other online truck accessory dealers. For installation, read the printed directions AND watch the YouTube video. It’s only 7 minutes long but will insure a perfect fit. I rarely do reviews. But this one ranked 5 stars!! Thank you BAK Industries for a nice product! ... show more

  • Easy install
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed
After watching a youtube video, it took me about 45 minutes to install. It came to my house on time and in one box. All parts were there and it wasn’t difficult at all. Great product that will protect my property in the bed of my Ford F250 truck. Looks great too!

  • Easy Install, Sturdy Product
Installed in 30 minutes. No rocket science here, easy enough. The cover fits like a glove and is easy to operate. I've always had hard covers on my trucks, but they are a pain when you have to haul large objects. This one rolls up out of the way and secures with two straps. Security is better than most other covers. ... show more

  • Bak makes a great product......but
Pattern Name: BAKFlip G2 | Hard Folding Size: 8' 2" Bed
I bought a topper for my 2022 ford expecting the same value as an Undercover bed cover. the first one not so much. But read on. The seller was great, even offering to handle the sale and return, if that is the direction I decided to go. I got in touch with BAK, and they stood behind their product 100%. The unit I received leaked at the hinges and the top was dimpled with 14 very small dents. I will receive a replacement cover in a week or so. It is refreshing to deal with a reputable company again. Way to go Bak and Parts hawk!!!! ... show more

  • Easy install and looks great
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed
1) Delivered on time. 2) All parts were there. 3) Easy to follow instructions. 4) Surprisingly SUPER easy install. I did it alone in about 15 minutes. 5) Looks great, low clean profile that looks like it was installed at the factory. 6) I only gave one star for durability simply because I’ve only had it a week. Time will tell. However, it seems solid, doesn’t feel at all like a cheaply constructed disposable product of China. 7) My only criticism is with regard to the drain lines. The tubes provided should be a slightly narrower diameter to fit in the bed wall holes without having to drill them out. Also, a couple of 45 elbows tossed in to direct the drain tubes towards the bed wall would be nice. I was able to use what was provided, and it will definitely “work” but, still went to Ace hardware and bought elbows and tubing that will be a cleaner look and more functional. Again, what’s provided will definitely do the job, I’m just one to always try and “build a better mousetrap”. Overall I’m very happy with the cover and highly recommend it. ... show more

  • Super easy to install and works like a champ!
Pattern Name: BAKFlip MX4 | Hard Folding Size: 8' 2" Bed
I looked at the Bakflip MX4 and the roll-up X4. Went with the MX4 as we tow our 5th wheel and for all intents and purposes, the MX4 will lay flat when open. Or basically, I could look out the back window and see a roll or I could look over a 4 or 5" flat (but open) cover. Simply stated...that was the deciding factor. With that being said, I'm very glad I did! The cover was extremely easy to install, especially if you watch the quick installation video. I don't think it took me more than an hour to unpack and install. In then end, it looks great and functions extremely well. As luck would have it, we've had several instances of literal downpours that lasted for an hour or more and honestly....no leaking or nothing that I could easily detect. The installation is on a 2019 F350 and the securing or locking of the cover works exactly as advertised. You have to drop the tailgate to get to the release cable and it's a pretty snug fit! I've always had canopies and this is my first tonneau cover. Would I do it again? In a heartbeat! ... show more

It looks very good on my husband’s truck. He got it professionally installed by a small business company.( only because he was rushed for time)
