When you’re hauling tools, gear, or groceries, keeping them dry and out of sight matters. The Revolver X4s uses a double-coated, reinforced vinyl layer over 1/4" thick, aircraft-grade aluminum slats to keep the bed covered and your cargo protected. The matte black finish resists UV damage, while beveled edges and weather seals direct rainwater off the sides of the cover—no drain tubes required. Even under heavy rain or in the car wash, the cover stays tight and secure thanks to its self-tensioning frame.


Large equipment or weekend projects often call for the full bed, and with this cover, that’s easy. Just unlatch the rear slat, roll the cover toward the cab, and secure it with the built-in straps and buckles. The cover stays up off the cab with cushioned bumpers, giving you all the room you need to haul big loads. Because it mounts inside the bed rails, you keep full use of your stake pockets for accessories like tie-downs or ladder racks.



You get the convenience of a roll-up cover with the toughness of a hard cover. The interlocking aluminum slats automatically latch down the sides and rear when you close the tailgate, forming a rigid barrier that can’t be easily cut or pried. Once the tailgate lock is engaged, the bed is sealed from front to back. The Revolver X4s supports up to 400 lbs of evenly distributed weight, so it’s built to handle real work.



The Revolver X4s sits just about 1-1/2" above the bed rails for a nearly flush, low-profile appearance. The matte black surface gives a uniform look from cab to tailgate, matching modern truck styling without bulk. The self-tensioning frame keeps the vinyl smooth and tight so it doesn’t flap or sag over time.



Installing the Revolver X4s is straightforward and doesn’t require drilling. The rails clamp inside the bed with pre-installed shims and slotted brackets that make alignment easy. Once mounted, the cover rolls out and locks securely into place with built-in latches on both sides. That means you can go from open bed to fully protected cargo without tools or hassle.

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.

I see that this cover comes with a five year limited warranty. The manufacturer prefers to handle all of their own warranty claims. I will send you their contact information via email.
