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. .

    • Well built, tight fitting and low profile
Style: BAKFlip MX4 Size: 5' 10" Bed
Impressed with the design on this. Its low profile, fairly easy to install. Make the truck look good. I gave it 4 out of 5 on installation due to i needed another body to help hold a corner down to have it sit right for bolt down. Even that, wasnt difficult at all. RTFM and golden. I tested it thru many a carwash (Crew Carwash) which has high pressure. Hardly any water gets in. Little by the tailgate. We'll see how it holds to sun damage/coloration and the weather. I personally think it will do well! Foldup: This is a must if you use the bed for hauling things. This top folds ups nice and easy. Simple pull down on the cable and flip it over! The mfg states it can hold up some weight. I'm not going to try it unless I have to. I trust what they say. Its a solid top. If you are thinking on this one, dont hesitate! ... show more

    • Smooth install and quality product for my 2023 Silverado
Style: BAKFlip MX4 Size: 5' 10" Bed
First, I spent a fair amount of time doing research for a decent tonneau cover. When I purchased my truck, I knew I needed a tonneau cover. I initially was leaning toward a retractable-style cover for a couple of reasons. One - I wanted something that would make my bed both secure and dry. Two - I wanted something that would be out of the way when I needed the full bed and was electric actuated. Third - I was fairly certain I wanted something constructed of metal rather than plastic or vinyl. There was one issue with electric retractable tops is they are VERY expensive! So, eventually I had arrived at the conclusion I just didn't want to spend the money for a retractable top, but wanted the sturdiness of a metal retractable top. BakFlip hits 2 of my 3 asks for a tonneau cover - AND at a fraction of the cost! So, this is MY comparison contrast between retractable vs folding tonneau covers. Next, when it arrived, it was packed very securely. I was a bit worried after I had ordered because I had read some reviews that indicated their cover was damaged during shipping. The box was large and bulky, but wasn't unmanageable. My 17 year old daughter actually got it into the house just fine on her own. Installation. My advice on installation is to unwrap the cover and brackets and separate the hardware into piles (nuts, washers, lock washers). The other reviews on here are spot-on! If you are like me and you're a garage 'tinkerer' with cars and trucks and know your way around a toolbox, you will have no problem with the install. It took me about an hour. Just be sure, to pay attention to the alignment and insure the brackets are grabbing your bed rails squarely. Definitely worth going back around to give the bolts a final 'snug' when you're done. Performance. I saw mixed reviews on here that were indicative of the cover leaking. The cover (so far) has kept the gear in my bed dry during the handful of rainstorms we've had since the install. As for the dust? Here's the thing. When you put one of these covers on, you are sealing around the top of your bed. The penetrations and voids UNDER that cover will allow dust (and in most cases water). How is it the tonneau cover's fault? Get creative if you want your bed to be air-tight. Overall, I am pleased with this purchase. In the end I am happy that I decided to save about $1600 because, as it turns out, I don't think having a remote and being able to click a button to retract the cover is worth an extra $1600. I hope this review helps if you are on the fence like I was... ... show more

    • Very easy to install
Style: BAKFlip MX4 Size: 5' 10" Bed
Top notch tonneau cover. Very easy to install. I really like the low profile. It's not 100% waterproof but only leaked a small amount after going through the car wash.

    • Still one of the best covers IMHO
Style: BAKFlip MX4 Size: 5' 10" Bed
I have the same cover on a F150 that I've had for a couple of years. This one was easier to install as I have a spray in bed in this truck vs the drop in bed liner. I really like the ease of installation, the ease and versatility of using it and the overall sturdiness. I would have given it 5 stars except that when it's in the full open position, it blocks the bed camera which is disappointing. One other minor thing is that the edges of the aluminum rail at the sides of the panel which meets the tailgate are shiny aluminum vs painted black - a little thing but given the price and the fit and finish of the rest of the unit it was unexpected. Quick fix with a little dab of paint. ... show more

    • Don't waste your time
Style: BAKFlip MX4 Size: 5' 10" Bed
Don't waste your time. Installed on a GMC Sierra AT4X. I have installed several covers and usually this is a good brand but this was junk! The rails went on fine and I always expect some adjustment of brackets to get the fit just right but this took me forever to get the driver side to latch properly. I did finally get it to latch but as I was doing a few open and close test I dropped down the last panel and the corner piece of plastic broke off. I am sure they would replace it but why have such a weak point at the corner like that. I am also not a fan of how the back fits over the tail gate, maybe mine specifically just had weirdly bent rubber that would smooth out over time but as it closed the first few times it was far from water tight. I have usually had good luck with Bakflip but for this truck I am looking elsewhere. ... show more

    • Cover Install on a '25 Silverado
Style: BAKFlip MX4 Size: 5' 10" Bed
My second Bakflip cover, same style, first one was for a 2023 Colorado and now a 2025 Silverado, both look great on the vehicle and function properly when properly installed. One of the problems here lies in the instructional video that they point you to for assembly because they give you a slip with a QR code linking to the RealTruck site, instead of written instructions, and some important details are glossed over or not shown very well. The other problem that was common between the two covers was the adhesive parts were either too weak, or too strong. With the too weak, they'd not adhere properly and fall off over time, with the too strong, they'd stick to the backing they are initially attached too and rip right off of the bumpers they come on. The only positive about RealTruck is that they are willing and able to send replacement bumpers and seals should that happen, provided you can prove you own the thing. The security aspect is nice, it's the only real reason to get a hard cover over a soft one, the water resistance is good, it never leaks water into the bed that i've noticed, but for the price it really aught to be better, the value at $1300 is not there in my opinion, however this was a brand I used before so I was willing to shell out a bit. ... show more
