RealTruck BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover | 448330 | Fits 2017-2026 Ford F-250/350 Super Duty 6' 10" Bed (81.9")

Very happy with product. Looks great. Easy installation - although watching/pausing/rewinding you-tube video vs reading a document was cumbersome. Seemed a little pricey but I feel like it is worth it after a few weeks.

This is more of an installation tip than a product review. I had already owned and used the BAKFlip MX4 on another truck, so I knew going in this is a tried and true good product ...likewise the high marks. But if you're installing one yourself, use a torque wrench when tightening the rail clamps! The instructions (and most of the DIY installation videos) say "DO NOT OVERTIGHTEN," but that's pretty vague. In fact, I don't recall seeing the installer in the video use a torque wrench at all. I figured I could just tighten the clamps by feel and be fine. But that was mistake ...well, at least for me anyway. I tightened them to what I thought was probably around 10 ft-lbs, but I was nowhere it. I was being overly cautious because I didn't want to apply too much force and damage the rails or clamps or both. As a result, I wasted a lot of time trying to figure out why the cover's latches wouldn't engage properly. Once I used a torque wrench and tightened the clamps to the manufacturer's specified 10 ft-lbs, everything changed. The rails pulled into the proper position, the latches engaged perfectly, and the cover worked exactly as it should. Bottom line: Don't guess at the clamp tension. Get a torque wrench and set it to 10 ft-lbs. It will save you time, frustration, and a lot of second-guessing whether you've tightened the clamps enough—or too much.

1) Delivered on time. 2) All parts were there. 3) Easy to follow instructions. 4) Surprisingly SUPER easy install. I did it alone in about 15 minutes. 5) Looks great, low clean profile that looks like it was installed at the factory. 6) I only gave one star for durability simply because I’ve only had it a week. Time will tell. However, it seems solid, doesn’t feel at all like a cheaply constructed disposable product of China. 7) My only criticism is with regard to the drain lines. The tubes provided should be a slightly narrower diameter to fit in the bed wall holes without having to drill them out. Also, a couple of 45 elbows tossed in to direct the drain tubes towards the bed wall would be nice. I was able to use what was provided, and it will definitely “work” but, still went to Ace hardware and bought elbows and tubing that will be a cleaner look and more functional. Again, what’s provided will definitely do the job, I’m just one to always try and “build a better mousetrap”. Overall I’m very happy with the cover and highly recommend it.

I don't care for the clamping system that is used, they utilize the grip of the clamp to hold the rails (and thus the entire tonneau cover) to the truck bed. The clamps otherwise are not physically attached to the rails, and if the nuts happen to vibrate loose just a little, the clamps literally fall to the floor of the bed. Murphy's Law, if it can happen, it will happen... They say it never has, but I can't in good conciousness leave my driveway with it on. From there, because I made sure the clamps were tight, the rails are slightly past vertical (even with the angle shims that were attached), so there are resulting alignment problems with the top, and it has to be worked to open, fold, unfold, and close. And I wouldn't dare loosen the nuts on the aforementioned rail clamps to get it better aligned... The little pad strips that are included are imo insufficient to protect the back window and third brake light (it's cheap, and doesn't cover the contact points adequately or at all). I'd feel compelled to get a large piece of foam to cover the back window and strap it somehow to the cover. And btw, it does block most of the third brake light. The prop rods in and of themselves are ok, but the attachment/adjustment point sucks. Once put into position and tightened, it will move if you apply some pressure to it. How tight do you have to get it before it strips out...? This is something that would be used repeatedly, No intention to be negative here as I'd prefer to be writing a positive review. But if I'm buying something at this price, I certainly do not want to be having to figure out how to modify it to make it safe and secure, or to prop it up so that it works as advertised, and doesn't break out my back window, all on DAY ONE...

Easy to install and a great look. I did have trouble with the latches at first but I think the gaskets needed to settle in

This cover was easy to install watching video and reading the manual. Both are online. Take your time and pay attention to the details and it will fit perfectly with no leaks.

What a beauty. Had it on my f150 for 12 year and held up great. Installed it today on my 2024 f350. Only issue I have is that the video instructions aren't very good for the 8'2" bed. Had to look at the video from a third party. Nevertheless great product.

Cover arrived damage free. Installation was under an hour by myself. At first the clamps annoyed me and I thought I needed another hand. However, and in regards to the review that says its terrible and if loosened the clamps will just fall off, not true. What took a minute to figure out, and comparing to other clamp rail type covers I've installed, the aluminum clamps will snap into the rails. Once you figure out where to install them, "roll" them into place and they will snap into the track and stay there. This also frees up from needing a 3rd hand. Until the clamps start getting pretty tight, the rails will sit on an angle. This also had me baffled at first as I was trying to keep the rails level and as soon as I started tightening the rails would lean in badly. Once it starts getting tight, the rails will level out. Take your time, be patient, its not a hard install and looks great when complete. Oh also, until you get it really tight and the rails straighten out, the latches will not catch. So if your latches dont catch, check your rails and be sure they are level on top. Quality seems nice, looks incredibly clean, folds easily, latches nicely and feels very solid. However, mine, even after a re-install just to try, is the furthest from watertight. The next amount of wetness would be no cover at all. My entire bed was soaked after a hard Florida rain while truck was parked. This makes it hard to decide if I'd buy one again or do another soft roll up that seem way more waterproof than a cover that is 4 times the cost. But the BAK is far more secure. So, leaking is my reason for 3 stars. If it was 95% dry like my soft cover, it would no doubt be a 5 star cover.

Seems like a great product but missing several components, including the rails which are obviously very important! I have contacted Bak Industries to have the issue resolved but have not heard back yet.
