Rain, snow, or dust—this cover keeps your gear safe from it all. The BAK Revolver X4s has a double-coated vinyl top over 1/4" thick aircraft-grade aluminum slats that lock together to form a tough shell. Those slats give it real strength—up to 400 lbs evenly distributed—while the matte black finish resists UV damage and everyday wear. Integrated rubber seals and beveled edges direct water away from the bed without the need for drain tubes, so your cargo stays dry wherever you go.


When you’ve got larger items to haul, you don’t have to take the cover off. The Revolver X4s rolls up quickly by hand and secures behind the cab with built-in nylon straps and sturdy buckles. The inside-the-rail mount means you can keep using your stake pockets for tie-downs or racks. It’s the flexibility of a soft cover with the durability of a hard one, all in one clean design.


Opening and closing this cover is quick and easy. Just press the rear slat at the tailgate to lock it down—no snaps or Velcro to fuss with. When the tailgate is closed and locked, the integrated latches along the rails automatically secure the cover from front to back. To open, pull either release cord at the back corners, and the whole cover rolls up evenly. It’s a one-person job that takes just seconds.




The Revolver X4s sits nearly flush with the bed rails for a clean, factory look. The matte black aluminum underbody and reinforced vinyl surface blend seamlessly with the truck’s lines. Felt strips underneath protect the finish and your hands in hot or cold weather. It’s strong, sleek, and stays tight thanks to a self-tensioning frame that keeps the cover taut season after season.

Getting it installed doesn’t require drilling or complicated tools. The rails clamp directly inside the bed using pre-installed shims and adjustable brackets for a snug fit. Once it’s tightened down, the frame sits square and secure, ready to roll. Backed by a 5-year warranty, the Revolver X4s is built for reliable use day after day.

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.

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.

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.
