BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover | 448339 | Fits 2021 Ford F-150 5' 7" Bed (67.1")

Upgraded from the factory Ford trifold. This top is perfect. Fits excellent. Automatic tailgate opens and closes as it should with no interference. Had a major storm yesterday and the box was completely dry except for some water on the tail gate, which I expected. There is a small clearance at the tailgate to allow for the automatic tailgate release. You could adjust it closer if you need. I'm very satisfied. Looks so much better too.

This is my second BAKFlip hard cover. Had one on my GMC which was destroyed by a falling tree during a tornado passage. After replacing the vehicle I purchased this one from Amazon and installed myself on my new Ford. This one is better and lighter than the original model. Fairly water resistant, but water from a driving rain creeps in from the tailgate area and a little on the sides. If you are carrying something than should not get wet you might consider keeping a trap as extra protection as I do. The best thing about any type of cover for your truck bed, is that once the bed is covered whatever is under the cover is out of sight and out mind. So those tempted to "take what they see" is avoided. The advantage of a sectional hard cover vs a solid or soft cover is the ability to access the full bed easily and lock it closed when the tail gate is up. This cover I found easy to install by myself in about an 1.5 hours. Watch a video, once you figure out how to mount the rails and where to run the water drain tubes it is very easy. My other cover was on my GMC for 10 years and it held up so I am expecting this one to perform similarly.

Quick delivery, well packaged, no missing parts. Easy install. Looks great. Was deciding between the X4s and the M4 but I like that the M4 can be partially open. The X4s is either fully closed or fully opened. Very satisfied.

Absolutely awesome tonneau cover for my 2016 ford f150 5.5' bed. Installing it was a breeze and very straight forward I highly recommend this tonneau cover to anyone thinking about buying one. Keeps everything in my bed nice and dry. Important note is when installing the bed rail clamps, you really have to lock in the clamps into the rail channel so when tightening it up it pushes the rail upward so when closing the tonneau cover it locks in perfect. Fits perfect on my truck and for the price of this cover it's well worth it.

great quality and easy to install, all parts were included. makes the truck look better and everything is secured in the back.
