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. .

  • Excellent fit and perfect for towing a 5th wheel.
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
I wanted a bed cover that was decent quality and one that could withstand the heat of Arizona summers. I did a lot of research and this fit the bill for me. You can open it up partially to allow towing a 5th wheel while still covering a 1/3 of the truck bed.

  • Great customer service when I asked a couple of questions!
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
No dislikes. Excellent quality and I had a small reason to contact customer service, they were on top of it and resolved promptly. This product also fits the 2024 year model, Amazon seems to have yet to update the website in the product description and custom fit. This is my second vehicle with this product, the first being a 2018 F-150. Loved it then and even more so now! ... show more

  • 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

  • Nice cover but fit and finish needs more attention
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
This is a nice cover, concept is on point, but (there's always a but) the factory needs to pay attention to some of the little things. First the rubber on the front of the cover doesn't stick very good or at all, on my first trip the rubber on the passenger side blew off, the driver side is hanging on for dear life. Second this happens on both sides, the rubber that runs down the sides that is supposed to keep water out, we'll it folds inside the cover, I'm sure that when this happens and it rains or you go through the car wash stuff inside is getting wet. These are little things, however when you pay a premium price you expect stuff to fit better, you kind of expect the molding pieces to stay attached, the seals to stay in place, not curl under. The molding that is under the panels, these are also peeling off, I just didn't get any pics. Also, beware that of you go anywhere that it's hot and your truck sits in the sun, wear gloves because the panels, the pull cords, everything gets extremely hot. Ask me how I know... ... show more

  • Easy install

Super easy install. Not water proof but only small amounts of water get in. Love I can open it to use a gooseneck or fifth wheel. Perfect

  • Not as durable as I hoped
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
Two weeks after installing on my '22 Silverado 2500HD, I was getting something out of my truck bed and noticed that something fell off the back of the truck onto the ground. I picked it up and found out that it was a corner piece of the cover. Then I looked at the other side and found that the one on that side was already missing. Considering it was brand new and had not even really had any use or abuse, I was kind of surprised. I decided not to return the item because that would involve uninstalling and repacking the entire thing, and most likely the replacement would have the same issue. Also, it's not like I can just order a replacement part, because the parts that broke off were part of the metal frame. I would have to have the entire cover replaced. Now I have water leaking into the rear of the bed, and the moisture is creating rust on the tools I keep stored in there. I still like the cover, but for the price I expected a much more durable product. ... show more

  • corners are very flimsy
Pattern Name: BAKFlip MX4 | Hard Folding Size: 6' 10" Bed (HD Series)
This is my second bak-flip. I was really satisfied with the first one but my new Chevy has a 4 inch longer bed so I had to buy a new one. The design of the corners is terrible, held on but a very thin strip of plastic (see photo) and broke in the box. I didn't notice until it was installed and then found the missing corner in the box in the trash. It's still a great cover but I don't feel I should have to do a gorilla tape fix on a $1000+ product! More to follow once I file a warranty claim... ... show more
