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.

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.

Perfect Fit

I have had 3 tonneau covers on 3 different F150's.From a vinyl top to a roller. the ease of installation and use of this cover bypasses them all. i may sell my roller and purchase another one of these to replace it. I really like the style and overall use of this top. I like being able to use the entire bed instead of losing the area for the roller. You will not go wrong purchasing this top.

BAKFlip MX4 installation

I had to dismantle part of the MX4 latching bracket and reinstall it, making additional holes in the cover. Because the person who assembled it, did not allow for any adjustment for alignment! I was not very happy!!!

Satisfied

Overall I was pleased with this product , looks good held up to some pretty good South Florida rain storms without any water in the truck bed . If you can get an extra set of hands for the installation it help tremendously, other than that no complaints.

BAKFlip MX4

Installed the MX4 on my 2019 Raptor. Mine arrived in perfect condition with no scratches, dents, or dings. Installation was a breeze and fits perfect. Had one big rain storm and did get slight water around wheel well area on both side so not sure it wasn't fully latched along the seam between the wheels. Overall great product.

Seems very watertight. Install pretty straightforward. Last panel has to be really slammed to close. Maybe once it breaks in a little will close easier. Overall a great cover.

Functional but expect better quality for the price

This is my second BakFlip tonneau cover. On the previous truck I had the VP vinyl covered model which is no longer offered. It is functional and there are few folding tonneau available that allow them to be folded up against the back glass allowing full access to the bed. Some of the details just seem cheap, when paying this much for a product I expect a little better. Prop rods are held place with wire clips, there's got to be a better solution. Ends of the rails are left unfinished.

Works well, but a little tricky to close

The cover installed pretty easily. It looks great, and seems to be high quality materials. The one gripe I have is that when I close the back panel, one of the sides does not want to latch easily. I have to slam it down from that one corner. It's a minor annoyance, which might could be corrected somehow.

I like older model

Easy to install, but i used to have the bakflip G2 and liked it much better. The G2 had a completely flat appearance that fit inside the bed rails & tailgate. This one sits over the tailgate allowing you to close tailgate with the cover down. I would prefer the no profile G2 & have to close the tailgate first (not a big deal.) it appears this one would be easier to break into by resting on top of the tailgate. Also noticed rain comes through at corners of tailgate, not completely sealed

Great cover

Quick shipping. Love the matte black. Easy install. I had to fix one of the latches because it wouldn't let the cover close all the way. But overall a solid cover.

nice cover with a little design flaw

You can lift this cover on the back side of the #2 panel just before the wide hinge allowing access the the locks on #3 panel. Other than that its a nice cover.

Looks great. However....poor quality control.

Upon unpacking, found one of the railings had a pretty good dent/bend in the flange that sits vertically next to the rail. The other rail had a smaller dimple in the same place. These were clearly not caused by shipping, the stuff was well packed. These didn't affect the appearance, as it's hidden with the cover on. Other quality control problems: metal shavings at a number of of the drilled holes and a misaligned plastic bolt guide/spacer. Poor instructions. Looks good.

Nice cover

The BAKFlip MX4 was just what I was looking for. I chose it because of the fact that you can close it without having to open the tailgate first. It completes the look of the truck and adds lockable storage. Installation took about an hour, taking my time.
