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. .

  • Great product and even better customer service
Style: BAKFlip MX4 Size: 5' 9" Bed
Fantastic bed cover. I bought this through amazon because it would be to me faster than through other various bed cover and truck accessory websites. It also ended up being cheaper through amazon. I received it in 48 hours and installed it in about an hour. I recommend watching the instructional video if this is your first install. It went in easily and looks very clean, to include the drain plugs that you don’t even see. It seals very well. Not water tight but there is so little water that may work it’s way in that it slowly will make its way out of the bed through the normal indentions in the bed. My only initial concern was that the cover I received had some spots on the edge seal(s) that were a little damaged. Well I contacted Bak and was immediately replied to. After providing the requested information and photos they manufactured and sent me an entire new cover right then and there. The only request was for me to destroy the damaged one and send a photo. This makes sense because I’m sure I could have easily sold even the one with the bad seals for several hundred. But I took the opportunity to see how it stood up to a ten pound sledgehammer. It did exceptionally well. This thing is so durable that the hinges took at least 5 direct hits with the sledge and were barely warped. Obviously I was able to go through the panel but only with a strong hit. Bottom line is this is a tough, mostly weatherproof, clean looking product. The only thing better than Bak’s product is their customer service. (And I was not paid at all for this review nor was I asked to write it) ... show more

  • Very Happy Full Circle
Style: BAKFlip MX4 Size: 6' 7" Bed
Very happy with this product. The main reason for purchase was to keep my equipment, luggage, etc sheltered from the elements. Although there are some tiny spots near the tail gate where a very small amount of moisture/rain seeps in, overall it does a good job otherwise. Super easy installation and removal. The last time I removed the cover so I could load my dirt bike, the corner caps near the tailgate fell or broke off. I contacted Bak Industries and they sent me replacements at no cost. Very happy with the full circle experience. ... show more

  • So far I'm pretty impressed with concerns
I like how it looks and what it does for the bed. I just installed it today after work and then went right to the car wash to pressure wash the truck in a manual stall. I spent $11 and went overboard. After i got home I checked the bed and it had water, but not very much considering what it went through and not having any time for the seals to lay flat from coming out of the box. I think the corners are the biggest issue. The front being the most with my spray in liner I had to use a foam strip to get any seal. so I'm guessing in a normal rain it will be almost completely dry. Being in Florida, I will know likely know within the next week and I will report back. I'm not a fan of the idea of drilling a hole in my new truck with 350 miles to mount something I may not be able to keep. I ended up running the hose into the holes for the front moving tie downs instead. Not the best setup, but should keep the rail water out of the dry area. I have yet to load my bike in the truck and I'm worried this won't work. It doesn't take up a lot of room, but I don't see how it's going to hold up with a bike up against it. I just looked at the images again and it looks like they have a tire chock in the bed. I didn't notice this before and may be the reason I send it back. During the summer I try to ride twice a week and winter get cut back to once. I'm not going to mount a tire chalk or remove and install this cover each time I ride. They could have made it much easier to remove and re-install, but didn't. If you don't need to haul a bike and want a good looking way to have a dry locked up bed. This is likely one of the best choices for you. I will report BAK on the bike part later. LOL Sept 2016: The D rings are steel and rusted very very fast. The only awful part of the product. How much would it cost to go with stainless instead? The last leaf I'm going in all the time has loosened up and is not as stiff, but everything still works fine and if the D ring wasn't junk I'd completely love this thing. ... show more

  • Why did I not buy it sooner.
Style: BAKFlip MX4 Size: 5' 9" Bed
Easy to install. I did it by myself. Anybody with home tools can do it. Love to protection it brings. No more worrying about leaving stuff in the back of the bed when on travel with kids for sports. Looks great. Love the flush fit. Enough water protection. No more putting crap in plastic bags. I even got around 1.5mpg more on my 2017 GMC Sierra 5.3L. I don't have a lead foot. If driving 45-65mpg you'll see it. Anymore than that you won't see much. ... show more

  • Customer support is the worst there is. DO NOT BUY
Style: BAKFlip MX4 Size: 5' 9" Bed
The latching mechanism broke for this cover. (Very fast after the install as it is fairly flimsy/cheap plastic). Called customer support for a replacement (warranty) and they said they don't even send this part...instead you have to purchase a new $80 bar kit which requires riveting into the bed cover. Not to mention that I was passed around 10 times before someone could even tell me this...it's a bit ridiculous. When I looked at the bar latch kit...it had horrible reviews....mainly due to customers simply never receiving theirs from shipment. DO YOURSELF A FAVOR AND GO TO THEIR WEBSITE TO LOOK AT REVIEWS. The bed cover is nice enough but I would never buy from them again on customer support alone. ... show more

  • Great buy!
Style: BAKFlip MX4 Size: 6' 7" Bed
I’ve only had this a few months prior to purchasing I noticed people complaining about it, not lasting long because of the rubber and plastic. All I did was spray UV protectant on the entire cover. Just got to take care of it. It’s common sense, exposed to the outdoor atmosphere and living in Arizona that heat and UV destroys stuff. Overall it was easy to install looks good I could actually stand on it but I only weigh 160 pounds, but I definitely tested it out and it does hold up. We’ll see how it does in the summer. ... show more
