If you’re carrying tools, camping gear, or anything you can’t afford to lose, this cover gives you the peace of mind of a hard shell in a roll-up design. The BAK Revolver X4s uses 1/4" thick, aircraft-grade aluminum slats covered by a double-coated, matte black vinyl skin. That combination blocks out weather, resists impact, and can support up to 400 lbs evenly distributed. The aluminum body prevents cutting or prying while the vinyl surface keeps a sleek look that matches the truck’s lines.
When you need to haul something tall, there’s no need to pull the whole cover off. Just drop the tailgate, release one of the corner cords, and roll the cover forward. It secures neatly behind the cab using built-in nylon straps and sturdy buckles, leaving the stake pockets open for tie-downs or accessories. The hybrid slat design rolls evenly every time, so you’re not fighting with misalignment or bulky folds.
Some covers stick up and make the bed lines look bulky. The Revolver X4s sits nearly flush, only about 1-1/2" above the rails. Its all-matte black finish carries through the vinyl top and aluminum underbody for a clean, uniform appearance. Beveled edges and integrated seals direct water off the sides so it stays tight and smooth through rain or sun without drain tubes or adjustments.
Opening and closing the cover is as simple as pressing down the rear slat. When you do, the built-in latches lock along both sides, and the rotating teeth clamp onto each slat for a secure hold from front to back. With the tailgate locked, the bed is sealed and protected without extra steps or Velcro to fuss with. Pull either release cord to roll it back up in seconds.
The clamp-on rails mount inside the bed with no drilling required. Slotted brackets and pre-installed shims square themselves for a snug fit, so you’re not loosening and retightening clamps to get things aligned. Once in place, the frame stays tight, the cover rolls smoothly, and you get a tough, low-profile solution built for everyday use.

Glad to hear you are still happy with it, Todd! These hard roll up covers are definitely nice and durable. What are you keeping in your bed? I have a bunch of survival type gear in a milk crate. Can never be too prepared!

The cover has been on my truck for a little over a year now. It looks exactly as it did the day I installed it. By far the best tonneau cover I have ever put on one of my trucks. Also, the roll up is much more convenient than the older tri-fold models I have had before. This thing looks good and is tough as nails. It has not been babied over the last year, but shows no signs of weartear. My one year review is 5 STARS!! I highly recommend this cover!

My previous review still stands. I have to reposition cover at least once a month. Still love the cover other than that issue. I believe a redesign of the connector would be in order for this product to get 5 stars.

Not great anymore… the glued on waterproof liner started peeling up about 1 year into service, the the pivot points on the tool up part started to separate towards the back and now it doesn’t roll back flat or seal properly.

I had a second warranty claim in June 2023 due to the same issues. I contacted BAK warranty claims and once again they were quick to respond. I asked them to replace my cover with a BAKFLIP MX4. They agreed and shipped the replacement very quickly. So far the new cover is working fine. Im interested to see how it works in cold and freezing conditions. My personal belief is the BAK Revolver is too heavy when rolled up against the cab on an 8 foot bed. The weight causes it to flex, stressing the hinged ribs. The ribs then start to separate. Im guessing a cover for a shorter bed would not cause the ribs to separate due to less weight when rolled up.

The Tonneau Cover has been working Great no leaks. I really think this product works as advertised. I would and have recommended this product to other people.

Two years in and still very pleased. I get compliments frequently for the tidy appearance and minimal bed capacity impact. One more gotcha I should note: when below freezing, it’s rigid and can be difficult to roll away. Generally a minor issue for me in the mid-Atlantic mid morning sun warms it enough that it’s OK. However, having spent time in NY last winter there were times I simply couldn’t roll it away without concern about damage. If you’re in a more northerly climate, be aware.

After one year of owning and using this thing is still amazing. It may have faded just a little bit but looks great and is holding up extremely well.
Do you have a question about this Tonneau Cover?
