The Revolver X4s blends the strength of a hard cover with the flexibility of a roll-up. Beneath its one-piece vinyl top are 1/4" thick, aircraft-grade aluminum slats that lock together for a rigid, cut-resistant surface. When closed, the latching system secures the cover from front to back—simply drop your tailgate and pull either release cord to open it from either side. Once latched, it stays tight against the rails and can’t be lifted when the tailgate is locked, keeping tools and gear protected from weather and theft.



This cover is built for everyday use through rain, snow, and sun. The matte black vinyl skin is double-coated and reinforced over aluminum bows to resist tears while maintaining a sleek, flush look that sits just 1-1/2" above the bed rails. Beveled edges and integrated weather seals help channel water off the sides without drain tubes. The felt underside prevents scuffing and keeps the slats rolling smoothly even after temperature swings or long-term exposure.


You don’t lose any bed space with this design. The Revolver X4s rolls up level with the top of your bed rails and secures behind the cab using built-in straps and buckles. It stays clear of your rear window for good visibility and leaves your stake pockets open for racks or tie-downs. With no bulky canister or obstruction at the bulkhead, you keep every inch of usable bed space for large loads or fifth-wheel towing.



Mounting the Revolver X4s is straightforward—no drilling required. Clamp the frame rails inside the bed rails, align using the slotted brackets and pre-installed shims, then fasten with a wrench. The design self-levels as you tighten it down so the cover sits evenly across your bed. Once installed, it can support up to 400 lbs of evenly distributed weight and is backed by a 5-year warranty for long-term peace of mind.

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!

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.

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.

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.
Do you have a question about this Tonneau Cover?
