When you’re hauling tools or gear, you want a cover that keeps everything protected from rain, dust, or snow without giving up strength. The Revolver X4s combines ¼" thick, aircraft-grade aluminum slats with double-coated, reinforced vinyl for a tough, weather-resistant barrier. Rubber seals and beveled edges direct water off the sides, while the matte black finish resists UV damage and looks clean year-round. It’s strong enough to support up to 400 lbs of evenly distributed weight, so you get hard-cover durability with soft-cover flexibility.


You don’t have to choose between a sleek cover and usable bed space. The Revolver X4s rolls up by hand and secures behind the cab with built-in straps and sturdy buckles. That means instant full-bed access for hauling large items without removing the cover. Because it mounts inside the bed rails, you still have full use of stake pockets for tie-downs or racks. The self-tensioning frame keeps the cover tight and smooth every time you roll it out.





Opening or closing the cover is quick and easy. Just drop the tailgate and pull either release cord to roll it up, or press down on the rear slat to lock it shut. The integrated teeth along both rails automatically secure the cover from front to back—no Velcro, snaps, or adjustment needed. When your tailgate is locked, the cover locks too, so your cargo stays secure.


Unlike bulky covers that sit high above the bed, the Revolver X4s sits only 1-½" above the rails for a clean, flush appearance. The matte black aluminum underbody and smooth vinyl top keep the truck’s lines simple and refined while adding scratch and impact resistance.


Mounting the Revolver X4s takes just a wrench—no drilling required. The side rails clamp inside the bed and feature slotted brackets and pre-installed shims that help them align squarely for a tight, even fit. Once installed, the integrated bulkhead seal and felt-lined slats keep the cover snug and quiet through every mile.

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 have bought two of these toppers. I like the ability to throw stuff on top while I open the tail gate and not worry about damaging it. It doesnt take up room in the bed when it is rolled up. It is secured with two straps and never contacts the cab. It doesnt like being rolled up for extended travel. The tabs along the side that fit into the rails come out and prevent the topper from fitting flush into the rails.
