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.

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.

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.

Great Bed Cover

I have had multiple BakFlip Covers. By far the MX4 is the best so far. I like how it is lighter and stronger that the previous generations. Super easy to install and fits well with the Adarack Cargo Racks for the Bed.

BAKFlip MX4 Review

Very good quality construction and operation. I'm definitely pleased with it, although it leaks a little; not enough to worry about though. Strong and looks good. Had three very small parts missing that aren't very important, but customer care was very good on getting those replaced.

BAKFlip 4 is Amazing

This BAKFlip 4 folding tonneau cover is great. Installation is a breeze - even for one person. Instructions are precise and easy to understand. It fits perfectly and works like a dream. I took a 2500 mile trip shortly after installation and it kept all mt cargo dry and well protected. I highly recommend this BAKFlip 4 tonneau cover.

Very nice looking and easy to use product.

I have a short bed 2020 Ram Rebel with Ram boxes. This was easy to install [under an hour] and slid right into the rails that came with the truck. the only issue was one of the supplied rails had a small ding from shipping which I had to straighten out for it to slide into place. Very happy with the product so far - seems to be water tight as it sat outside in some very heavy rainstorms. A little pricey, but the quality seems to be there for the money and ease of installation.

We love the way it looks on the truck. Matches the texture perfectly to my bed caps. Haven't had it long enough to see how leak proof it is. I would buy for my next truck.
