Description:

Whether you’re transporting a load of furniture to a new house or want to keep your gear out of the weather and away from prying eyes, your stuff deserves the ultimate in open-road protection – the BAK BAKFlip MX4 Folding Tonneau Cover, of course.

Up or down, the BAKFlip MX4 tonneau cover offers full truck bed access thanks to an integrated tailgate seal and long-lasting latch housing components. The truck bed cover has sturdy prop rods on each side, you can even drive at normal highway speeds with the cover fully open. With everything secured by the integrated buckle system, everything will stay in place, and traffic behind you will still have full visibility of your third brake light.

The MX4 sits flush with your bed rails when closed, giving your truck a clean OEM look and feel. Manufactured from heavy-duty aluminum panels – with panel skins 1.5x thicker than the BAKFlip G2 – this tri-fold tonneau cover combines functionality, durability and rugged good looks. And we haven’t even mentioned the dense foam core yet. Well, now we have. Finally, a UV- and scratch-resistant matte black finish and low-profile fit make for a super sharp look from any angle.

But perhaps the most impressive feature of the BAKFlip MX4 folding tonneau cover is the maximum weight rating of 400 lbs! So, you don’t worry about it caving in any time soon. And the manufacturer-backed 5-year warranty will give you peace of mind should any other mishaps happen.

You’ll be happy to know that your new BAK BAKFlip Folding Tonneau Cover doesn’t require any drilling and can be fitted to your truck with a factory-installed look in 30-45 minutes. Plus, you’re still covered by the AutoAnything return/exchange policy and our lowest price guarantee.



Frequently Asked Questions

How secure is the BAKFlip?
Out of sight, out of mind has a significant value in any truck bed cover, but you can lock your cargo secure by simply locking your tailgate. This makes the pull cables which release the cover become inaccessible and turn your truck bed into a lockable storage compartment.

Will BAKFlip damage my cab if its flipped up against the cab?
No. BAK uses D-shaped bumpers to prevent any direct contact between the cab, the back window and your BAKFlip.

Can I drive with the BAKFlip folded open?
Yes, new straps and buckles have become standard on new BAKFlip models. Strapping the cover down flat on the rails behind the cab allows incremental access to the bed and improved rear window visibility. 

How do I lock the BAKFlip if my truck does not have a tailgate lock?
If your truck does not have a locking tailgate, a Pop & Lock or similar lock can be added to your truck to complete the bed security. Sold separately available at AutoAnything.

Is my BAKFlip waterproof?
Ultimately no truck bed cover is totally waterproof. However, if properly installed the BAKFlip in a leader in its class at keeping the bed dry. Although gaps at the tailgate and other areas of the bed can allow minimal water in, there are also special installation techniques to become the most watertight fit possible.

Looks nice, poor quality

My new 1000 dollar backflip came apart at the tailgate release cord, then bolts holding it together stripped in cheap aluminum framework. Nice quality!

Excellent Fit to 2020 Honda Ridgeline

Installed the cover myself, took me about 3 hours. Probably would have been a little bit shorter if I was mechanically inclined. The drain tubes on the Honda Ridgeline are much smaller than the ones provided with this kit. If you want to set up a DIY drain setup that is compatible with the Honda Ridgeline, please visit the forums here: https://www.ridgelineownersclub.com/threads/bak-flip-drains.185754/

Great tonneau cover fits perfect

I chose the MX4 from bakflip because it has the look and style I want for my Tacoma. The fit and quality is great Easy to install and took about a hour.shipping was good for 2021 it came 6 days before promised. I recommend thos cover for anyone wanting or needing a tonneau cover to keep things in their truck bed dry and out of sight, locking the tail gate and you should be good to go.i still have use of the entire bed when needed and can be removed in minutes if needed.

Sharp looking, easy to install

This is the third different type of tonneau I have tried and by far the easiest to install and also my favorite.

Very nice but.....

first off the quality of the fit and finish of the bakflip mx4 is great. I have one suggestion for improvement and had one issue with install. The opportunity for improvement is to have all panels have the locking tab to hold it down firmly in the track system. The improvement would be to have it fit the truck without having to redrill and adjust at the tailgate. Other than that I like!

MX4 for my AT4

This is my second mx4 cover. I had one for my 2018 sierra, now I have one for my 2020 sierra. Bakflip made a few improvements, but there is still a small gap from the top of my tailgate and the cover itself.

Love it

Fits perfectly try on my 2006 Tacoma Long bed. Install was easy. Looks amazing. It's rock solid so far. One thing to note for 2nd Gen Tacoma owners...you will lose your bed rails. I installed extra bed D-Rings so I am OK with this.

Not bad

Cover looks awesome. Had some water entry issues. Think I got is squared away. Cover came a little "rough around the edges" prob from manufacturing. Need the cover to stay, so I can t send it back. Few silver areas that should be black. All in all, nice cover.

BAK BAKFLIP MX4 Review

Product is nice, but some of parts seem to be rather cheap plastic , in the folding joints on each side little small rectangle parts being loose or comes out when you open and close top, on small pieces on end by tailgate are loose and will come out and can get lost, and the pull strings used to open each flap don't work proper, with several attemps of alignment one side you puul string hard and top is hard to open .

Easy to install and looks great!

This was really easy to install although I would say do not do it on the hottest day of the summer in direct sunlight. It looks great and is secure.

2017 Ford F-450

Absolutely a perfect fit widthwise and lengthwise. So easy to install the rail system prior to the cover itself. Adjustments were as per instructions and common sense. The longest time I spent was perfecting the drain hardware for my front bed usage. THIS IS A PLUG AND PLAY mechanical installation for any and all DIYers!!

Great product, easy install

I'm loving my BAKFlip for my F-150. Looks great, no leaks so far. The only reason I did not give Ease of Installation 5 stars is because when I received the cover there was no installation package. I had to wait another week to get that. But once I did installation was easy. I highly recommend this product.
