High quality product
This product is awesome. Love the fit, how it looks on my truck and the overall quality. This product is fairly straightforward on installation recommend two people as it is much easier with two.

Super Easy Install / Looks great.
Just got done installing my RealTruck BAK Revolver X4ts Tonneau Cover on a 2024 F350 platinum. Super easy, one person install. Everything fit perfect and no interference with my auto tailgate. Looks great.

Ford F-450 Platinum, near perfect fit, worth $$$
Excellent product, near perfect fit. - All hardware is well engineered and sturdy. - Flush fit, looks great. - Top is very strong. - No documentation regarding the 8’ bed rail connectors, closeup and printed insert in package would be helpful - A closeup of the clip in rail insert geometry closeup, printed insert in package would be would helpful. I’d give 4stars but the dam thing is so cool, it works fantastic with my Ford F-450 Platinum. *** It’s worth the BIG $$$ THANKS.

An Hour to Install is delusional.
If I could give lower stars I WOULD! I called RealTruck, for assistance because I can't get the cover to latch down. AND NO, it's not an alignment issue. I took it off and reinstalled it making sure to aligh perfectly left to right front to back and it still won't latch down. When I called the manufacturer for assistance RealTruck told me since I bought on Amazon THEY DON'T SUPPORT IT. It is unfortunate because the I think it is a quality cover and looks good. Just can't get it to latch up. If it won't latch it won't secure and if I don't have confidence i won't lose my things then I don't need it.

Cover is great, instructions stink
This product is great! I had it on my last truck, so I knew I wanted another for my new truck. It says you can install the cover in 30 minutes. This is true, but not if you follow the included instructions. They are pretty terrible. After watching a YouTube video, it was actually a piece of cake, and the cover is working fantastic.

Great support and product.
Easy to install. Fits well. Durable. Great support. I’ve had this over a year now. The only issue I had was one of the plastic corners fell off which Bakflip replaced immediately. On the install, you need to ensure the brackets are exactly at a right angle to the bed. This takes a bit of adjusting otherwise the back locks won’t clip. My suggestion would be to increase the latch clearance a bit. I had issues with getting one side to latch but after using it for a bit, now both sides latch when I close the cover.

Time will tell, but I’m optimistic…
Something of a fiddly installation on my ‘25 F350 long bed. Be prepared for much tightening and loosening of the various clamps (do employ a torque wrench… in the end it makes things easier) in order to square the cover up in its tracks. Nothing difficult about the installation, it was just time consuming to get everything just right. I found two (of eight) slam latches required shimming in order to function. Having written all that, the finished product looks good, seems secure, should keep things under it pretty dry… I think I’ll be happy with it.

Easy to install. Impressed with the fit on my F250.
Really nice fit. Easy to install. I like that it cannot be opened without opening the tailgate. If your tailgate locks, the cover will be secure. No cover is completely water tight. Have not tested it with a wash or rain yet but judging from how it looks, I bet this is one of the best covers when it comes to keeping your cargo dry. Looks great on the truck. Very happy with my purchase. Plus saved $100 by purchasing on Amazon vs one of the other online truck accessory dealers. For installation, read the printed directions AND watch the YouTube video. It’s only 7 minutes long but will insure a perfect fit. I rarely do reviews. But this one ranked 5 stars!! Thank you BAK Industries for a nice product!
