Very happy with the cover. If I ever need another I would buy it again.

Was a easy install , only had it for a week

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.

Love that I can have a cover on my truck while towing a fifth wheel. It folds up nice and latches to stay out of the way of the fifth wheel hitch. Then I can keep items in the back of my truck while camping and they are secure (my tailgate locks).



by:

This cover has held up well. I would buy this again if needed.
No water leaks around the cab area or the sides. Have a one inch gap at the tailgate. I have sedan expansion foam strip to help seal off the tailgate. Does well at the car wash. The sides have a water or rain gutter that diverts water out the back of the truck.



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.



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:

Overall satisfied with it. However, the end caps get loose and we lost one within a month. I contacted BAK manfufacturer but have not heard from them. Rather poor service.
Other than that, the only other problem is that the middle hinge often closes with misaligned plastic piece, easy to spot (hinge is buckling) and press the piece into the the rail.



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!



by:

Well made cover. A lot sturdier than I thought it would. Its not full proof so water does get in the bed but it's minimal. The cover partially blocked my tool box which sit in the bed, so I removed the tool box cover for easy access.



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:

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:

Easy to install. Doesn't leak. Easy to clean, and seems to have improved my fuel mileage a bit. I am happy and would highly recommend this cover. Fits my 2018 Silverado perfectly.



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:

Cover went on easy and looks good on the truck. We put it on our 2020 Colorado which we tow with our motor home. It works great for extra secured storage. The only problem was with the rubber bumpers on the bottom and the two on top , fell off as soon as I opened the box. Not a big deal just had to use a little gorilla glue on them and all has been good.



by:

the bedcover finally came in.
Few pictures
of it installed.



by:

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:

Great cover. Love the protection it del ivers!



by:

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



by:

After a year of using the cover I found that there are a few things that could be improved and you can do some of these yourself.
The knobs for the cover that actually hold it into the bed-vibrate loose. I added my own lock washers. The poles that you use to hold the cover up when the cover is raised up against the back window-they also vibrate loose-so often that I just removed them and keep them under my seat. The little u-clip pole holders for the poles when not in use-they are too weak-often letting the poles jump out or fall out during normal road driving.
The cover itself is not waterproof --it sheds water away mostly however enough gets into the bed that you can not trust your items to be dry. Bag important stuff to keep it dry.
The rear weather seal slides back and forth too easily--sometimes working itself out about 2 inches until you see it and slide it back into place--i addenda small amount of silicone to stop this from moving.
The cover is strong, looks good and is mostly what I was looking for. Unfortunately I would not buy this again-even more because you have to relocate the bed accessory rails-which then limits the items you can buy for your truck because they are designed for the rails to be in the factory positions.
My next cover will be a roll up so that it allows visibility out of the back window. When this cover is flipped up to its final position it completely blocks the rear window. When I was looking at covers-my thought was well its the coolest looking cover and I can deal with not seeing out the back window--well that has changed. It is not practical. The price is high and there are many other options out there that are. My soft roll up tonneau cover was great-waterproof and I could have bought 6 of them for this price. If one was damaged it would have been better to just throw it away and order a replacement. Sorry guys-look elsewhere for a better cover.



by:

great easy to install and looks good



by:

Love the MX4 ...Took a little longer to install but looks great...



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.

  • Recommended Tonneau Cover For a 2024 GMC Sierra 2500 Compatible With Thule TracRac Ladder Rack
    I recommend installing the BAKFlip MX4 Hard Tonneau Cover on your 2024 GMC Sierra 2500. You will need either the 6-3/4' # BAK448133 or 8' # BAK24FR cover depending on your bed length. These covers will fit the Thule TracRac which fit the SR rails. If you have a TracRac TracONE # TH27000XT style ladder rack you will need the following components to convert it to fit the SR Rails. Modular Base LF/RR # TA01-42003 Qty 2 Modular Base RF/LR # TA01-42004 Qty 2 Knob # TAKB-90030-1 Qty 4 Nylon...

  • Rapid Switch Pro On A 2021 GMC Sierra 2500 HD with 610 bed with Bakflip MX4
    The BakFlip MX4 is compatible with the Rapid Switch Ladder Rack # RS77FR. These systems work well together and the Rapid Switch System is the same for the 8 foot and 6-3/4 foot bed. For your tonneau cover, it all depends on the length of your bed. If you're wanting to get the BakFlip MX4 and you have a 8 foot bed, get this one # BAK24FR and if you have the 6-3/4 foot bed get this one # BAK448133. The rails are long enough to go from the bulkhead of the bed to the tailgate. I have an installation...

    The BAKFlip MX4 Hard Tonneau Cover # BAK24FR will fit your 2022 Chevy Silverado 3500 Dually. DRW will not effect the fitment of a tonneau cover. This quad-fold cover sits inside your Chevrolet Silverado 3500's bed rails and secures upright for unrestricted bed access and will allow you to use certain stake-pocket mounted ladder racks without having to remove your cover. The tailgate will open and close with the cover up or down.

  • Will the B&W Companion Fit Under a Tonneau Cover on a 2022 Chevy Silverado 2500?
    While we have not tested the B&W Companion Hitch # BWRVK3710 with the BAKFlip MX4 # BAK24FR on an 8-foot bed 2022 Chevy Silverado 2500, there are things we can look at to give you a good idea of compatibility. The first thing to note is that the Companion has three hitch height settings, with the lowest being 17 inches. We also know the BAKFlip MX4 will sit approximately 1-1/2 inches below the top of your Silverado's bed rails because this is a low-profile cover that installs inside the...

  • Length of BAKFlip MX4 Tonneau Cover When Propped up Against 2024 GMC Sierra 3500 Window
    Hey Jason, The BAKFlip MX4 Hard Tonneau Cover # BAK24FR panel closest to the cab is about 23" long according to my contact at BAK. They also said they can't guarantee one way or the other if it will block your 3rd brake light camera on your 2024 GMC Sierra 3500. As an alternative, I recommend picking up the BAK Revolver X4s # BAK54ZR because it gives you the security you're looking to get out of a hard cover, but it has individual slats so instead of folding up it rolls up. The roll will...
