Features to know about
Secure Cargo in Any Weather: Heavy-Duty Aluminum Panels
Keeping your gear safe from rain, dust, and snow shouldn’t mean giving up on convenience. The BAKFlip MX4 uses ½" thick, rustproof aluminum panels with a premium-density foam core that adds strength while keeping weight down. The matte black finish resists scratches, scuffs, and UV damage, so it stays looking clean even after years of use. Seals along the rails and a built-in drainage system direct water away from the bed, helping keep cargo dry through storms and car washes.
Full Bed Access When You Need It: Tri-Fold, Fold-Up Design
When you need space for tall or oversized gear, the tri-fold design folds up fast for partial or full bed access. Prop rods hold the cover upright so you can drive with the bed completely open, and integrated buckles let you secure the panels in folded, flipped-up, or closed positions. You don’t have to remove the cover to haul large items, and it stays low enough not to block your rear window.
Low-Profile Look That Plays Well with Racks: Inside-Rail Mounting
The MX4 sits flush inside the bed rails for a clean, factory-style appearance. Because it mounts inside the rails, you can still use stake-pocket accessories or a rack system without interference. That means you can pair it with ladder racks or overland setups while keeping the bed protected underneath.
Simple Security: Automatic Latching System
With automatically latching panels, the bed locks shut as soon as the tailgate closes. You can open or close the tailgate with the cover up or down, and the secure latching keeps your tools or gear protected from quick grab-and-go access. It’s a straightforward setup that gives peace of mind without extra steps.
Built to Last, Easy to Install: Rustproof Aluminum Frame
The aircraft-grade aluminum frame and rails are coated in matte black powder for corrosion resistance and durability. The rails clamp to the inside of the bed—no drilling required—so installation is fast and clean. Once it’s in place, you’ve got a solid, 68-lb cover rated to hold up to 400 lbs of evenly distributed weight, ready for years of daily use.

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!

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
Jason

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.

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...

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.

- Are There Tonneau Covers for 2004 Ford Ranger Stepside 6 ft BedHey Larry, yes we do have tonneau covers that fit your 2004 Ford Ranger stepside. I attached a link to all of them down below but a really popular option is the Extang Trifecta 2.0 part # EX92600 which is a folding vinyl cover.
view full answer... - What Ladder Rack Do You Recommend For My 2021 Ford Ranger With A BAKFlip MX4 Tonneau CoverThe BAKFlip tonneau covers are a good choice. I am not sure what size truck bed you have on your 2021 Ford Ranger, but if you have the 5' bed you would get the BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish, part # BAK448332. The BAKFlip MX4 for the 6' bed is part # BAK448333. My recommended ladder rack, that is black and compatible with your 2021 Ford Ranger is the Adarac Aluminum Series Custom Truck Bed Ladder Rack - Aluminum - 500 lbs - Matte Black, part # A39ZR....
view full answer... - Can you Use a Retrax Tonneau Cover with a Ford Performance Chase BarThe only option to use the Ford Performance Chase Bar on a Ford Ranger with a tonneau cover is to get a tonneau cover that sits inside the bed rails. The reason for this is because any cover that sits above the rails like a Retrax does will take up too much space on the bed rails for the Performance to mount. With that in mind, there won't be tonneau covers that have T-slots available since only the ones that sit on top of the bed rails have this option. I recommend using a BAK tonneau...

The etrailer Hard Tonneau Cover # e83DR for your 2024 Ford Ranger XLT 5' bed is going to sit approximately 1" above the bed rails.
