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 quality
Pattern Name: BAKFlip G2 | Hard Folding Size: 6’ 10” Bed
The description of this product was very accurate, it is very easy to assemble and the fit is perfect. My husband did it with no tools in about an 30 minutes. It is very durable and so far no fading.

  • Best Tonneau cover on the market
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
This is the BEST tonneau cover on the market! I was going to order it from Chevrolet and it was nearly $1,600.00. I looked on Amazon and it was less than $1,200.00 for the same cover. I watched the YouTube installation video by BAK that was incredible helpful, precise step-by-step instructions and easy to install. When I say easy to install, at 69 years old, I was able to easily install the cover by myself. While the cover itself is a bit heavy, when you balanced it correctly, it lifted into place in one easy maneuver. I highly recommend this cover to anyone who is looking for one. Thanks BAK for making an incredibly well made product, high-quality construction, and most of all, easy to install! ... show more

  • Very Good Cover!
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
This is the second BakFlip MX4 Hard Folding Truck Bed Tonneau Cover I've owned. I recently sold my old truck with the cover. Before that, I had a BakFlip G2. I love these covers because they are so versatile. I received the cover a day earlier than expected and It took about 45 minutes to install but I took my time. I can fold it up completely for full use of my truck bed, or I can fold up three sections and leave the fourth section down and snapped in, which is what I do when towing my Fifth Wheel. I like the extra security a hard tonneau cover provides because it can't be cut with a utility knife and the cover can't be opened easily when the tailgate is locked. There are two things that I wish were better. Some water will get in when there's a heavy rainstorm or you go to a high pressure car wash but that's true of all covers I believe. Second, after 12-18 months, the paint wears off in spots where the cover panels rub when folded up. This doesn't affect how the cover works and is only aesthetic. I would also like to note that having a tonneau cover on your truck will increase your fuel mileage. I have a 2020 Silverado 2500HD with a Duramax Diesel. I checked my fuel mileage before the cover was installed on a 50 mile trip and got 21.5MPG having cruise control set to 65MPH. Then I took the same trip after the cover was installed and got 23.9MPG. In both instances, the wind and road conditions were the same so I'm pretty happy about that. Of course this would be true of any bed cover but I wanted to make mention for those that were on the fence about whether to install a cover of any kind. You will save fuel. Overall, this is an excellent cover and I would recommend it without hesitation. ... show more

  • Nice solid cover
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
Good solid cover that you can fold up out of the way. The thick insulated panels keep your gear from getting too toasting under the black cover. Put 7000 miles on it and no issues so far and kept the water out from the top but you will still get very little water in from the tailgate vertical seams.
