The 2004-2015 Nissan Titan King Cab with the 6'7" bed gets secure, weather-tight coverage from the BAKFlip MX4. It clamps to the factory bed rails with no drilling and folds flush to the cab, so you keep the full bed for hauling while your cargo rides locked and dry. Heavy-duty matte aluminum panels sit low and clean over the rails and keep the weather off your gear season after season.
What's Included:
BAKFlip MX4 hard folding tonneau cover, pre-assembled
Two clamp-on mounting rails
Integrated tailgate seal
Drain tubes
Clamp and hardware kit
BAKFlip hard-folding install guide
Features
The Original Hard-Folding Cover, Now Gen 3 The BAKFlip MX4 defined the hard-folding category and the Gen 3 keeps it at the top. Patented auto-latching, premium aluminum panels, and a low, flush profile give you a cover that looks factory and works like it was engineered for your truck, because it was.
Automatic Latching Security, Standard The patented auto-latch system locks each panel down the instant you fold the cover closed, with no separate key or lever step. With the tailgate shut and locked, your gear sits under a cover that cannot be opened from outside.
Sealed Edge to Edge Against the Weather Revised EPDM perimeter seals and tight-fit clamps close the gap between the cover and your bed rails, and a longer dual-action tailgate seal protects the back edge. Integrated drain tubes carry water off the cover and out through the bed. Like any folding cover it is water-resistant rather than submersible, but it keeps rain, dust, and spray off your cargo.
Built Stronger, Built to Last Heavy-duty aluminum skins over a high-density polymer core make the Gen 3 panels about 22 percent stronger than the original MX4, with a textured matte finish that resists UV and scratches. This is multi-layer construction that will not bow or flex the way single-layer covers do under pressure.
100 Percent Bed Access, Brake Light Clear Fold the panels flush against the cab, secure them, and drive with the bed fully open for tall or oversized loads, no removing the cover. The MX4 is the only hard fold that leaves your third brake light visible in every position.
One-Person Install in Under 30 Minutes The all-new click-in design clamps to your factory bed rails with the included hardware, so most trucks install in under 30 minutes with basic hand tools, no drilling and no second person. Assembled in the USA and backed by a 5-year warranty with US-based product support.

BAKFlip MX4 Fast Facts
This Fast Facts video from RealTruck runs through the BAKFlip MX4 Gen 3" under two minutes: the heavy-duty aluminum panels that are about 22 percent stronger than the original MX4, the weather-resistant EPDM perimeter seals and integrated drain tubes that keep water off your cargo, and the re-engineered automatic latching that locks the cover down as you fold it closed.
You also see the 400 lb evenly-distributed load rating, the textured matte-black finish, and the no-drill clamp-on install, all backed by a 5-year warranty and US-based support.
One-Hand Operation
Drop the tailgate, release the rear latch, and the tri-fold panels fold forward toward the cab in seconds, no second set of hands needed.
The patented auto-latch system locks each panel down the instant you fold the cover closed, with no separate key or lever step. With the tailgate shut and locked, your gear sits under a cover that cannot be opened from outside.
Weather Stays Out
Revised EPDM perimeter seals and tight-fit clamps shed rain and spray across the whole cover so the cargo underneath stays dry.
Revised EPDM perimeter seals and tight-fit clamps close the gap between the cover and your bed rails, and a longer dual-action tailgate seal protects the back edge. Integrated drain tubes carry water off the cover and out through the bed. Like any folding cover it is water-resistant rather than submersible, but it keeps rain, dust, and spray off your cargo.
Frequently Asked Questions
Straight answers on specs, fit and support
Does it work with the Titan Utili-Track channels?
Yes. This BAKFlip MX4 fits the 2004-2015 Titan 6'7" bed with or without the factory Utili-Track system, and the clamps work around the channels.
Which Titan bed is this for?
This is the 6'7" bed, typically the King Cab on the 2004-2015 Titan. If your bed measures about 79", this is the right cover. The 5'7" bed uses BAK-448505.
Does the BAKFlip MX4 keep water out of the bed?
It is built to. Revised EPDM perimeter seals and tight-fit clamps block seepage, and integrated drain tubes route water off the cover and out through the bed. Like every folding cover it is water-resistant rather than fully waterproof, so in a hard storm or a car wash you may see a little misting at the seams, but it keeps rain and spray off your cargo.
Can someone get into my bed when the cover is closed and locked?
No. The Gen 3 uses automatic latching panels with reinforced latch housings. With the tailgate closed and locked, the cover cannot be opened from outside, giving you weather-resistant, lockable bed security.
How much weight can the closed cover hold?
The MX4 is rated for 400 lb evenly distributed across the closed panels, which is fine for gear, a cooler, or a flat load laid across the cover. It is not meant for concentrated point loads or for standing on.
Do I need to drill into my truck to install it?
No. The BAKFlip MX4 clamps onto your factory bed rails with the included hardware, with no cutting, trimming, or drilling, and most trucks install in about 30 minutes with basic hand tools. On applications that use drain tubes, the tubes route through existing bed drain points.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

2026 Maverick cover
This is my third truck to install bak flip tri fold hard cover. Each one was improved and better than the last. My only issue was a wrong part was packed with mine so I had to call customer service to ship out the correct part. I think I have had this issue on the last two covers. Issue was always resolved in a professional and professional way but it is just an added cost to you and an extra step for the customer. You dont expect this from this price point.

First box came without hardware. Second box came with everything but was not straight with one side being longer than the other. They kept asking me for pictures and measurements till I had enough and sent it back for a full refund. Will never buy anything from them again. The funny thing is ,this is the second time they asked me to do a review on their junk.

It leaks
Was initially impressed with the bed cover. Appearance is great, installation was easy. But after a rain, water pools in the middle of the cover and begins to leak in the middle of the bed. Ive had numerous bed covers (roll up/soft trifold/hard trifold) and they all leak and I understand that it is unavoidable. However, other bed covers have leaked towards the cab or at the tailgate. This one leaks right in the middle of the bed. For the price I cannot and would not recommend this cover to friends/family.

The Best Truck Bed Cover Yet!
In 2015, I bought my first BakFlip and transferred it to my second Ram 1500. Here in 2026, I bought my third Ram and decided to get the new BakFlip design and am glad I did. Very easy to install and it took me less than 30 minutes. I love the finished look - like it's from the Ram factory. I like that the folded panels are really secured in place when driving and won't get whipped in the wind plus it leaves room for maximum cargo space. The upgraded cable system for latching and unlatching is another big plus. They really designed a great product and I recommend it over all the others out there. . . well worth the money!

Nice product super easy to install but grab a friend its much easier. Product fits the bed nicely. And the lathes made it easy to fold up. If I had one critique I wish the cover on the Cab side was convex to match the shape of the bed on my 25 raptor. Small critique would make it perfect other than that it still gets an A+ from me.

Amazing Bed Cover
The BAKFlip MX4 was real easy to install and works great. Drove through a severe down pour and everything in my bed remained dry. I feel it may be helping with gas mileage as well. The individual sections allow me to access the everyday essentials in the rear of the bed without having to flip the entire cover open. Worked perfect for camping.

GREAT Tonneau Cover!
This is a fantastic tonneau cover! It fit my 2025 Ram 2500 perfectly! The only issue I had, and it was my own fault, is I was trying to assemble it using Gen 2 instructions and not Gen 3 instructions. Had I used Gen 3 instructions, it would've taken much less than 30 minutes total. This cover is good looking & tough! I would absolutely recommend it!

BAKFLIP MX4 JUST MAKES SENSE.
I made my purchase right as the newer updated version was released. I tend to over research a product before making a purchase but the MX4 was the one that made the best sense to me. Its a great product. Very easy to install, real low profile and does a great job keeping water out. It seems very durable. I think it will last years. I really have nothing to protect in my bed but I really like the fact that it improves on highway mileage gas mileage. I have one issue. I think the plastic clips that are on the two of the latches to hold the nylon straps need to be more durable. One of mine was broken on delivery(thanks FedEx). I really just wanted a replacement latch cover but they sent me a complete unit when I reached out to the excellent customer service team. Sent it back because it had deep scratches on the top. Ill figure something out. Overall I am very pleased with this product and

As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome.
