Features to know about

Full Bed Use: Tri-Fold Aluminum Design

When you need to haul large gear or tools, it’s nice not having to take your cover off. The BAKFlip MX4 folds up in sections so you can open as much or as little of the bed as you need. The integrated prop rods hold the cover upright when fully open, letting you drive with the bed completely clear. The low-profile, flush-mount design keeps the look clean and doesn’t block your view out the back window.

Everyday Strength: 1/2" Thick Aluminum Panels

If you’re loading heavy boxes or climbing in the bed, you want a cover that can take real use. The MX4 uses 1/2" thick, rustproof aluminum panels with a premium density foam core for extra strength. It’s rated to handle up to 400 lbs of evenly distributed weight, so you can load gear on top when needed. The matte black finish resists scratches, scuffs, and UV damage, keeping it looking sharp through years of use.

Weather Protection That Lasts: Seals and Drainage System

Rain and snow are no match for the MX4’s solid build. Matte black rubber seals wrap around the edges, and an integrated drainage system channels water away from the bed. The rear seal lets you open or close the tailgate whether the cover is up or down, keeping your cargo dry without slowing you down.

Secure and Simple: Automatic Latching Panels

With the tailgate closed and locked, the MX4 automatically latches each panel for a secure bed. You can flip open the cover quickly when you need access, then close it again knowing your gear is protected. The built-in buckle system keeps the cover steady in folded or upright positions, so everything stays locked in place while driving.

Built for Real Use: Easy, No-Drill Installation

You don’t need special tools to get this cover installed. The frame rails clamp inside the bed rails for a clean, no-drill fit, and bolts secure the front hinge rail for extra stability. The aircraft-grade aluminum rails with a black powder coat finish add to the durability and tie the whole setup together. This is a cover built to work as hard as your truck, season after season.

Video Transcript for BAKFlip MX4 Hard Tonneau Cover In-Depth Review and Installation

Hi, I'm Daniel with etrailer, and today we're going to take a look at and I'm going to show how to install the BAKFlip MX4 hard tonneau cover. This tonneau cover is one of the premium ones we have on our site. It's basically going to turn your truck bed into a huge trunk. And these are really nice because it's going to keep water out as well as would-be thieves. So it's going to give you that peace of mind. All your stuff in here is going to be nice and safe.

This cover has a ton of cool features that others don't. The first being you can open your trunk with this fully closed and vice versa. Some, you have to close your trunk before you close your tonneau cover. So I can get this open here and close it without a problem. A lot of the other ones, there's a seal in the way and it could damage it, but this one there's no issue there.

And to open this up, you can do it from either side, but there's a pull cord. You pull that and it'll just flip. Each section will have a pull cord. And another nice feature is you can drive around with this folded up. So if you're hauling around really heavy stuff that sticks up above your tonneau cover, most of the time you'll have to take your hard tonneau cover completely off, which is a huge hassle.

But with this one, there's a prop rod and you can loosen this knob, slide this down, tighten it back up. Just do that on both sides and you're good to go. You can drive around with this. And they did design this so each section would be small enough so it folds up and you can still see your third taillight. So again, when you're driving around, you can have it folded up and still view that taillight.

If you are planning on driving around with it folded up and you might be worried that this vibrating against your cab might damage it, but they do give you durable thick pads you can stick on here. So that won't be an issue. You can also fold it down once and there's clips. So you can clip these on both sides, tighten them down, and that'll keep this from vibrating if you want to drive around with this in this position. This kit is really nice because it's super easy to install. These side rails will just pop on and then you're going to have three clamps per side. You just want to tighten those down and then you get this inner section in place and that's really it. Now another thing I want to mention is when this is folded up, it's going to be super flush to your bed. So this really only sticks up probably less than half an inch. So it's going to be nice clean sleek design. This is also super durable. It's aluminum panels and this can support up to 400 pounds evenly distributed. So if you're at a job site, you maybe want to throw some tools up here or even some plywood, this can handle a lot of weight. But like I said, this is going to be your premium option, but the neighbor who owns this truck, he likes it so much. He actually had three of these. He originally had an F-150 that he got, but he traded in for a F-250, got the same version, and now he's got an F-150 again and got it again. So it's definitely a great tonneau cover to get. Now if you have any further questions about this product or anything else for your truck, please feel free to reach out and I'll be happy to point in the right direction. And like I said, install is super easy on this. Won't take you long at all, but if you don't have the time or tools or space to do this in, you can check out our installer locator and we can find an installer local to you to get whatever you need installed. If you want to do this yourself, follow along and in this video, I'll walk you through the process. Starting off, you want to put the weather seal on the front of the truck. You just want to stick this down. It has a sticky backing on it, and you want to clean this really well with alcohol. And sometimes this rough texture, it's really hard to stick to. So I have sanded it down before with a file or sandpaper just to make it a little bit more flat just where you need to stick this. We can get our side rails up in place and you'll get this over the lip of your bed and push this all the way forward. So your drain tube is going to be facing forward, just want to push it all the way towards your bulkhead. We'll get our clamps on. I already got the front two. We want to get this one about eight to 12 inches from the front. I got that tightened up. And then for the middle one, I got that one roughly in the middle. If you have an eight-foot bed, you are going to need two of these in the middle. And what you're looking for is you want this rail to be perfectly flush with your bed, so you don't want this tilted down or tilted up. But how you get these clamps on, it's pretty straightforward. All you have to do is go in kind of at an angle kind of like this and then go down. I'll clip in like that. For the back part of our clamp, it's going to have the side with the long bend and you want the teeth facing in. I'll get that put in place. That's in the lip of our other bracket. Then I'll take our bolt with a flat washer, get this tightened in. There are filler strips that come in the kit and these can just stick onto the rail. We just want to stick these one closest to the tailgate, the other closest to the front, and then one in the middle. I'll use a 13-millimeter socket and get this snug down. And we can get all of these torqued down to these specs in the instruction. Now we can attach the drain tube on the part of the end of our rails and you are going to have to run this out. So if you don't have a plastic cover you can remove, you are going to have to drill a 7/16 hole. So our neighbor doesn't want this installed. He doesn't want a hole in his bed because he doesn't have any of those plastics to remove. But the best place is probably right here. You can just run this down right there or there is a hole right here, you could open this up a little bit, and run it right next to it. For our clips, we can get those installed and there's pre-drilled holes in here and you can just put your screw in, use a Phillips head. Don't use any power tools, just use a hand drive on this and get that tightened down. On the backside, there's going to be some inserts you'll just have to put in. That's what these thread into. These slots are going to be for our clamp. It's going to be a knob attached to a carriage bolt. I'll slide this in, and this part with the groove, this is going to go on our rail. That'll allow us to tighten this down. So I'll get this on both sides. We can take our tonneau cover. I'm going to lift this in place. We want to push this forward until this weather seal completely covers the front and you can always adjust this front and back a little bit later if needed. You're going to have more pads that come in the kit and you can stick this on this part where it contacts your cab. So just lean this forward and put them wherever you want. And we're ready to put this bracket and this groove on the lip of our side rails and I'll just tighten this down. With both sides tightened up, we can unfold this, make sure it clicks into your rails. And we'll shut our tailgate and you want this to be covered so water doesn't get in there. And if it's not enough, you can always scoot this back a little bit to how you like it. And that does it for look at our MX4 hard tonneau cover. Thanks for watching.

I love how this tonneau cover works. because it allows use of almost the entire bed of the truck when it's fully open. I was a little disappointed with the clamps for installing the side rails, as they didn't seem as robust as the clamps in the cover I bought for my last truck. However, I am happy with its operation, and the fact that the truck bed is a locked compartment when I lock the tailgate.

Thanks for the great feedback! We're glad you're enjoying the tonneau cover and that being able to use almost the entire truck bed when it's open has been such a big plus. It's also nice knowing your gear stays secure when you lock the tailgate. We appreciate you mentioning the clamps too—that kind of feedback is always helpful. Thanks again, and we hope you keep enjoying your new cover!

Bought it used.. I asked if it was complete undamaged.. It arrived complete including a scratch on the inside cover.. I'm glad it wasn't on the outside cover. Shipping was quick. Installation was fairly straight forward
by:
Ordered the BAKFlip MX4 for my son on 12/15 after calling to verify the tonneau would arrive by Christmas. Then received an email that said "Your order has been forwarded to one of our partners for direct shipment to you" and never received another shipping update or any tracking info. Finally on 12/22 I emailed Etrailer.com who told me they didn't know when I would get it. The Tonneau finally arrived on 12/29, 3 days after my son returned to California (he drove his truck, 2100 miles). He won't be back till next Christmas so I have to figure out how to return this product. I had several other buying options to get this here by Christmas, but went with Etrailer because of their reputation. This will be my last purchase from Etrailer.com.
by:
Overall, I am very pleased with my BAKFlip MX4. It has held up well after 1 year. It works well and looks good. It matches my matte black accessories and trim. It was fairly easy to assemble but I did have some tight fitment issues near the cab where the cover connects to the rail. I really like the security of the hardtop and access through the tailgate. Water is generally kept out, but sometimes there are water drips near the tailgate depending on the angle parked. So this cover keeps the bed *mostly* dry.
etrailer was very fast to deliver my cover, and it came in good condition.
by:
The bed cover has been great so far. Followed the instructions and took my time adjusting it and it has been working well. Keeps the bed dry and looks good. I did have to order an extra kit to get enough rail clamps. Once I put the extra clamps on it feels much more secure. For 8ft beds they need atleast 8 to 10 clamps, not 6. The cover has been working in that I don’t have to uncover the whole bed to use it. I just need to open up as much as I need at the time.
by:
So after a year I am still loving this bed cover. Had the fiberglass version for my 2013 F-150 and loved it as well, that's why I purchased this one for my 2019 Super Duty, it was also the first accessory I purchased for it because I was so used to my other one and knew I couldn't live without it. I never installed the drain tubes on either covers and still haven't had water get it my bed. Also the folks at etrailer are always awesome! Thanks again!

BAKFlip MX4 is a great addition to any pickup. It allows for secure transport of material, keeping it dry in bad weather and yet readily accessible with the flip of a panel. It also keeps the weather away from your 5th wheel hitch. Can be left on when towing.
by:
I have been using this cover for almost a year now, and am very pleased with it. It looks and fits great, and it is secure and keeps most of the bed dry in the rain. A couple of rubber trip bits have needed some improved securing, and I used a little RTV so it was easy. I drove it across the country round trip last summer and it was perfect. I would recommend this cover for a great-looking and pretty secure cover. Finally, it is easy to fold forward when it is time to haul loads taller than the bed rails.
by:
Purchased this BAKFlip for my new 22 RAM Classic 1500. Installation went well, instructions were good to follow, and it fit perfectly. One of the plastic hold down clips had a manufacturer defect with excess plastic mold residue inside the clip that prevented it from properly working. I sent an online warranty claim explaining the problem, and a new clip was sent to me in a reasonable amount of time, and it worked fine. After one year of using the cover, I am very happy with it. Everything functions as it should, and it is very versatile. While it is not 100% watertight, I mostly notice a small amount of leakage around the tailgate seal after washing the truck. Under normal rainy weather, there is no leakage, and we get plenty of rain in the PNW. My four-star rating rather than a 5 star is only because of the manufacturer defect and the curling of one of the rubber cushions on the underside of one of the panels where the adhesive holding it on the edges has not held up under the hot weather (with the black color, when the sun beats down on the cover it gets pretty toasty inside the truck bed with the cover closed). I am thinking that should be an easy fix by applying some good adhesive and taping in place until the adhesive cures. Just haven't gotten around to doing it. Again, really like this cover. Would recommend it to others, and if I ever have a need for one in the future, would definitely not hesitate getting another BAKflip.

The BAKFlip after 2 years is still functioning great. I fixed the curling cushion by applying some strong adhesive to the spots that had detached, taped it in place and let cure for a couple of days. That solved that issue. Would continue to recommend the BAKFlip to others.

Great tonneau cover. Fits as it should.

I installed the BAKFlip MX4 in my RAM 2500 Crewcab has the 6' 1/2 short bed, drived 300 miles now. good product, open and close the tailgate without lifting up the cover
by:
dodge Ram Pickup
Great fit on a Ram 2500 long bed. Everything stays dry on the inside.
by:
The cover functions ok. The tailgate leaks quite a bit. The manufactured edges that where cut were sharp and not painted or treated. The weather strip along the edges has already discolored/faded. Disappointed in the fading and less than ideal sharp edges. Somewhat expected leaks, but not this much. Average at best rating, especially for the price.
by:
Install was smooth and got a timely note when it was completed
by:
I am a huge fan of the BAKFlip. The installation was pretty straight forward and easy. Anybody with moderate mechanical ability can install. I think it took less than 2 hours. I live in a heavy snow area and had more than 24” of snow on it at one point and the product performed flawlessly.
by:
Excellent product! Wait time was crazy but manufacturer is to blame on that one!
by:
I replace a camper shell with the tonneau cover because it is easier to remove when I want to put my pickup camper on the pickup. I am very happy with the cover and am glad I made the switch.
by:
the bedcover finally came in.
Few pictur

I really love the bakFlip cover. It locks up all my stuff when we are on the road. I really like the looks too.
by:
I own three of these on three different trucks. The two I purchased this year and last year are not as good quality as the one I purchased in 2023.For the price they are feeling pretty cheap now and parts are falling off. Latch covers and rubber par to rest the top on when folded up have fallen off on both of the covers. I will not be buying these brand covers again.

Solid performance. Only issue is with the glue holding the pads is failing

Its still amazing. Works just like its suppose to glad I made the purchase.

by:
I have owned this cover for over a year and it has been excellent. It keeps the bed fairly dry as expected and I have had no mechanical issues with it as it still performs like new. I would say the only improvement I would suggest is better foam weather striping for the front of the bed as the original never stuck to the spray in liner very well and eventually came lose and then I just swapped with some similar weather striping I bought locally.

The cover is still excellent and keeps our items dry and secure on those road trips. I stand by my initial review and still wish the weatherstripping would stick the the spray in liner better but its only been a minor annoyance that hasnt resulted in any water getting into the bed.

by:
The cover has been great. I would buy it again. The only gripe from me is that for some unknown reason, one screw rusted ( as shown in the attached photo ). Why one, and not the other 3 ?? who knows...
by:

It's a straight forward assembly but photos of the assembly steps would be better than the illustrations.
NOTE: This model allows you to open and close the tailgate without lifting up the cover. The other models require you to lift the cover so the tailgate won't damage it.

  • Tonneau Cover Recommendation for a 2022 Toyota Tundra with a 6-1/2' Bed
    We have a variety of tonneau covers that are compatible with the 6-1/2' bed on your 2022 Toyota Tundra and out of the linked selection I like the BAKFlip MX4 Hard Tonneau Cover # BAK49AV because it's a folding cover that sits flush with your bed rails and has a matte black finish. All of this combined gives you a great looking tonneau cover that is able to completely secure your cargo as well. This fits whether you have the Deck Rail System or not, but you'll need to remove the system...
