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.

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!

Ram Classic

I have had a couple of soft tonneau's in the past, they don't last, the Velcro fails or the the cover dries out and they are not secure. I decided to spend the extra money for my new truck to eliminate those issues. I couldn't be happier. Installation took less than an hour and it looks great. Bakflip was the only hard folding cover that allows you to fold the last panel against the rear window giving you full use of the bed.

2019 ram 3500 big horn short bed

Had the same cover on my '07 Ram 1500 shortbed and it was a great cover and a breeze to install. The one I received for my new Ram with the same bed was a pain. the rails were too long, so the tail gate wouldn't close. Since my ram came with the plastic bed rail covers, the locking mechanism of the cover jammed and wouldn't operate properly. There was no ability to adjust the locks. Since I needed the cover immediately, I did what was necessary to make it work. Not a great experience!

Install was a breeze. Quality could be a little better. Flimsy arm holders. It does leak a little but I expected that from the reviews. Price point is high. Over all not a bad cover hopefully it holds up.

Excellent Product and Purchase Experience From AutoAnything

AutoAnything had the BEST price! Their order process was easy and efficient, communication was excellent, and the cover arrived quickly. Upon receipt I opened the box and was extremely impressed with how well it was packaged. I was impressed by the ease of installation, the tonneau cover quality, precision fit, the clarity and simplicity of the written instructions and the cover's final fit and finish. Overall, a quality product from BAK and an exception purchase experience from AutoAnything.

Quality Decline

I've done about 10 of these. All went well and looked amazing when done. This one must have been built on Friday at shift end. Horrible QC. Aluminum shavings everywhere. Bulkhead foam was dime store quality. Rubber seals are not symmetrical and were not applied straight at the manufacturer plant. VERY disappointed in this one. Zero attention to detail. It would also be great if AutoAnything would recognize that Ram is NOT a Dodge Ram...

Easy and quick install

Installation was unbelievably quick and easy. Product looks really good and sits almost flush with the truck bed. When unrolling I do have to check and make sure te weather seal on the sides did not curl in places. Also the corners where it meets the tailgate do not have water stripping so I worry that water can get in there. I have not tested yet.

RAM 3500 STD Bed BAKFlip MX4

Tonneau cover delivered with no damage, had it installed in less than 1 hour. I've had BAKFlip tonneau covers before and always bought and had it installed by a retailer...they are ripping you off. This product is simple to install, and as rugged as they come. I highly recommend this tonneau.

Great looking cover!

Due to recent back surgery, I had my tonneau installed by Truck Access Plus in Phoenix. The cover looks awesome on my 2008 Dodge Ram! Works like a charm and I like having the BakBox underneath. $ well spent for both!

Great looking

The installation was a little tricky to make it perfect. I basically was able to install it 90% of the way. But, great cover, looks good and is solid. Seems to help with gas mileage. My biggest thumbs up was I was able to install an auxiliary tank underneath perfectly. Never would know it is there. For that I give it 5 stars.

Quick and strong

I saw this cover online after researching the very best covers for my particular truck which is a 2017 Dodge Ram 1500 Crew Cab. I really like the design so I decided to spend the money. I am so glad that I did I really had it installed completely in 35 minutes. I get compliments all the time on how nice it looks and it gives me Total Access to the bed in less than 5 Seconds. You will not go wrong buying this cover!
