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. .

Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 7" Bed
Easy enough to install though did take some effort. Just follow instructions or look up a YouTube video and you will be fine. Once on it has been working great. I do get some water from the tailgate area but is minimal and doesn't pass one inch inside the bed. There isn't a seal here so i did expext this. Weater proof tape may fix it. Everywhere else remains dry. Easy to flip open as well. Overall cover exceeded my expectations. ... show more

I never thought I would spend so much for a cover but I'll tell you one thing, it was worth it. My truck bed looks amazing. I received so many compliments. I feel comfortable leaving my belongings in the back knowing the cover is strong and sturdy. Also no wind noise when driving at high speeds.

  • Dry and secure bed!
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
We just got a new truck a few months ago and on our first camping trip with it we quickly learned how much of a pain it is to feel like you have to move things like child carrier backpacks etc into the cab of the truck to secure it if you stop somewhere for lunch. We had a three week road trip to Utah and Canada planned and I knew we’d want a good tonneau cover to secure our cargo in the bed of the truck and keep it dry. After a lot of research on tonneau covers I settled on getting this one and can honestly say I couldn’t be much happier. While on our 5,000 mile round trip we drove through wind and torrential rain at times and everything in the bed stayed dry. Even after raining for two days straight in Canada. I did use the included drain tubes and had them drain out the holes drilled in the plastic plugs they tell you to drill through in the instructions. With getting up to 85 mph on some roads and with crosswinds I never had any problems with the cover rattling in the wind like I had heard one reviewer talk about. I think it may have been a fluke or possibly a different method of installation that may have given them the problem. Having the BackFlip Tonneau cover was a game changer for us and my wife and I were both so glad I had insisted on getting it before our trip. It was pretty easy to install on my 2020 Ford F150 and I had it installed within about an hour and a half including the time it took to find tools etc. It looks really clean and sleek and really serves its purpose quite well. I’d recommend it to my friends and anyone of you who might be looking for a tonneau cover. ... show more

  • Perfect fit
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
Arrived a day earlier than expected. Fits my F150 perfectly and looks great. It’s replacing a 8 year old Bakflip F1 cover that had started to come apart. I hope this one last longer.

  • Broken on arrival
**FINAL UPDATE** After my last update i did receive the replacement roll top and this thing has been flawless for a couple years (yea, totally forgot about updating my review). It has held up really well with Houston weather, operation is simple and keeps everything secure with minimal or no water leakage into the bed. Also i do not have any rattling or flexing while driving (generally 80+ mph down the interstate, gotta keep up with that Texas fast lane). Updating from 1 star to 4 stars, would be 5 if i didnt have all the initial issues. **UPDATE** Received a reply within 2 days of my original review, took me a few days to send the information they were requesting because I was busy with other things. They requested, Serial Number (located on a sticker on the underside of the cover, close to the bulkhead), Shipping Address, Proof of Purchase, and pictures of the issue (Please note: I don't know if theyre flexible with this but if you encounter issues, TAKE PICTURES!). I received a reply within 2 days of sending them the proof they requested and they stated a new cover will be sent to me and had additional instructions on what to do with the old cover, they did not request I send it back. They also stated that theyre sending the cover ONLY, all hardware and rail from the original purchase will be used again. Will update once I receive the replacement. Unfortunately because of demand, theyre estimating another 2 - 3 weeks before the new cover gets shipped. Keeping my 1 Star review until I have a working product. **ORIGINAL REVIEW STARTS HERE** Decided to pull the trigger on this $1K+ cover for my truck. A lot of reviews were read and watched, and seemed to really fit what I needed. A low profile hard cover that didn't take up any bed space and easy to operate. Well after waiting a little over a week I finally got the cover in and started my install. Install went well enough, nothing too difficult, but once I put the cover on to roll out and get positioned I noticed the first issue. The plastic guard piece closest to the tailgate that is supposed to help prevent peeling of the seal and guard you from sharp edges of the aluminum was broken off. Not a deal breaker, I've actually seen several reviews that said this has happened and BAK Industries has simply sent a replacement piece to clip on. Continued my install and noticed a bulge at the top of the cover towards the bulkhead, I immediately knew it was not supposed to look like that. So i went to investigate and to my surprise, one of the links to the cover was actually broken. This completely breaks the covers operation. The full siderail locking isnt able to engage, causes issues with closing, opening and the end of the cover itself (at the tailgate) ends up bowing causing a huge gap center of the tailgate and the side rails flex upward, also causing issues with contact with the cover and seals on the very corners of the tailgate. I have emailed BAK Industries and will hopefully get a reply soon with some sort of solution, if I don't I will be forced to deal with returning this thing. If they do respond and offer a solution I will update my review with information on that. ... show more

  • Great Bed Cover
Pattern Name: BAKFlip MX4 | Hard Folding Size: 5' 7" Bed
I read the reviews and saw people complaining about it not keeping your bed dry. I'm thinking those people didn't do a great install. This bed cover has kept my bed 95% dry. Minimal water gets in when there's a heavy rain near the tailgate and sometimes on the edge of the bed. It doesn't really bother me. I keep my generator in my bed sometimes and needed something to keep it dry and this fits the bill. It's also nice to leave things in the bed and not have to worry about security. It's a little pricey, but I'm hoping to keep it for years. If you need something that will 1. keep your bed dry, 2. last longer than a couple of years, this seems like the cheapest option. I think it looks pretty good too. ... show more

  • Sturdy, and great Customer Service!
Truly easy to install, easy to roll up and unroll. No worrying about alignment of bars under a sheet of plastic that almost always flaps when driving. I had a broken corner piece on the one I received. I called BAK Customer Service and they got the order for the replacement piece submitted right away. One of the better Customer Service experiences I've had in recent years. ... show more
