Get the advantages of both a hard tonneau cover and a soft tonneau cover for your vehicle with the Revolver X4s. This hybrid tonneau likely has an identity crisis. It's built like a hard cover, but it looks and acts like a soft cover. With the Revolver X4s, you get the strength, durability, and security of a hard tonneau and the sleek look and convenience of a soft, roll-up tonneau - all while protecting your truck bed and cargo and helping to improve your fuel mileage.


The X4s has the features of the original Revolver X4 with upgrades including a matte black aluminum underbody, integrated safety slat caps, rear corner caps, and an integrated bulkhead seal.


Strong, Convenient Hybrid Design

Fully installed coverPartially rolled up cover

The secret to the Revolver X4s's versatility is the aluminum slats on the underside of the cover that make it strong, seamless, and flexible. These individual, hinged slats give the cover its rugged body, while also allowing enough flexibility for the cover to be rolled up. Atop the slats is a tough, 1-piece vinyl layer that adds to the tonneau's sleek look and overall durability while also keeping the slats perfectly aligned. As a result, the Revolver X4s will roll up evenly every time, unlike ordinary soft vinyl covers that can get lopsided as you maneuver them.


Low-Profile Appearance

Cover sits flush for a low-profile appearance

Unlike other tonneau covers that sit 1/2" or more above your truck bed rails, the Revolver X4s sits nearly flush with your rails for a clean, ultra-sleek look.


Full Truck Bed Access

Cover rolled up for full truck bed access

The Revolver X4s gives you full use of your truck bed in a matter of seconds - just roll up the cover and secure it behind the cab. As a result, you can tote around all your gear without having to remove the tonneau. And because the Revolver X4s mounts inside your truck bed rails, you can still use your truck bed stake pockets to mount accessories like tie-down anchors.


Simple, One-Person Operation

Cover is closed and secure

The Revolver X4s is simple to operate. Following installation, just roll the cover out and press down on the rearmost slat at the tailgate to secure the tonneau in place. The built-in latches not only lock down the back end of the tonneau, but they also fasten the sides of the Revolver X4s along the length of the frame rails. The rail tooth runs the entire length of each frame rail. It rotates downward to lock the side rail into the sides of the cover.


Cover is latched closed

When the cover is rolled out and the rear slat is pressed down at the tailgate, the latches on both sides engage. When this happens, the integrated teeth pivot down and rest on top of each slat of the rolled-out cover. Closing the rear slat effectively pins the cover to the rails, ensuring that the cover stays closed from front to back. It's that simple - no Velcro to seal or snaps to wrestle with. When your tailgate is closed and locked, no one will be able to get through the cover, thereby safeguarding your truck bed and its contents. The cover automatically secures as the locking levers at the tailgate engage. These sturdy levers have reinforced gussets that give them added strength and durability. And they will never need adjustment.


Cover unlatched and partially unrolled

To roll up the cover, unlatch the rear slat by dropping the tailgate and pulling either of the 2 release cords located along the bottom corners of the slat's housing. Either cord will release both of the latches so that you can raise the rear slat. When the latches are disengaged, the teeth roll back into the frame rails, releasing the sides of the cover so that you can easily roll it up. Just fold the rear slat over and roll up the cover the rest of the way.


Rolled up cover secured to end of cab by buckle straps - from aboveRolled up cover secured to end of cab by buckle straps - from below

Then secure the tonneau behind the cab with built-in nylon straps and sturdy plastic buckles. These straps help to keep the bundled tonneau from contacting your cab while you drive. And 4 rubber bumpers act as cushioned barriers between the cover and your truck cab.


Heavy-Duty Construction

Heavy-duty, aluminum construction under matte black vinyl

The Revolver X4s's rugged aluminum and vinyl construction makes it an ideal match for your truck, no matter what you do while at work or play. This cover is strong enough to hold up to 400 lbs of evenly distributed weight when it's rolled out. The 1/4" thick, aircraft-grade aluminum slats are covered with a matte black vinyl skin for superior resistance to impacts, UV rays, and weather. This skin is what gives the tonneau its soft, sleek look. While the Revolver X4s may look like a soft cover, its aluminum skeleton provides exceptional security because it cannot be cut through in the same way that a standard soft vinyl cover can be.


Cover lays atop protective felt strips

Felt strips on the underside of the tonneau help to keep the slats from scuffing the vinyl top as you roll up the cover. The soft felt also shields your hands when the cover has gotten hot or cold. And rubber strips overlay your truck's side rails, cab rail, and tailgate, creating a seal that helps to conceal any gaps and works to prevent water from seeping in.


Easy, No-Drill Installation

Clamp-on installation

Installing the Revolver X4s is simple. All you need is a wrench, and you don't have to do any drilling. The tonneau's frame rails clamp to the inside of your truck bed side rails to create a base for the cover. The included bolts secure the front hinge rail to the frame rails at the cab.


Slotted brackets at the ends of the tonneau side rails allow the bolts to shift in case you need to adjust the cover to achieve a snug fit. These brackets ensure proper alignment of the tonneau frame on your truck bed side rails. This eliminates trial and error in installing your rails - you won't have to put them on and then take them off again to get the correct fit. Pre-installed shims and spacers also help to ensure that the Revolver X4s rails are installed squarely on your truck bed.

BAK Revolver X4s Hard Tonneau Cover - Roll Up - Aluminum and Vinyl - Matte Black - BAK56ZR

Average Customer Rating:  4.5 out of 5 stars   (83 Customer Reviews)

Weather-resistant, roll-up cover keeps the gear in your truck bed secure and dry. Rolls up quickly by hand for full access to your truck bed. Aluminum slats keep cover tight and help prevent break in. Requires no drilling to install.

by:

Literally the best cover there is on the market. It’s sleet. It’s durable and I get compliments everywhere I go. Thank you etrailer.



by:

Perfect fit, almost completely flush with the bed, very attractive, doesn't flop going down the road. Takes up no bed space when rolled up and does not impair rear view.

by:

Purchased this in February. By August this product was already failing. As a roll up tonneau you would expect it to not fail where the cover sits when rolled up but that is exactly what is happening. Photos speak for themselves. I do not recommend you purchase this.

Will be reaching out to customer service today. Will see how how well they support their product.



by:

Looks great. Seems to be good quality. If installing on a Ranger pickup, find ALL of the instructions, including the one in the hardware package that tells you what to do before step 2 of the main instruction sheet.



by:

Customer service from E-Trailer was exceptional as usual big shout out to Cammi F. Thank you for keeping me updated as this was actually delivered from manufacturer.



by:

The original cover was improperly sized from the factory (direct shipment from BAK due to backorder). etrailer, as usual, went above and beyond to get me the correct fitting cover. The new cover fits perfectly and looks great on my truck. Hopefully it will last, though I worry about the quality considering BAK did not notice they sent me a cover with the wrong dimensions originally. Giving 4 stars due to poor QA from the factory on the original shipment.



by:

I decided to spend more money on a secure bed cover about a year ago. This is a very robust cover and I would definitely recommend. It lets a little water in but other than that it has been terrific. The outside cover looks brand new and it locks securely. I would purchase again but it should last longer than I own the truck.



by:

The tonneau cover fits as advertised no leaks it has been a great addition to my truck I really like the way I have my whole bed to use and still have the security of a hard cover without blocking my view out of the rearview mirror for hoking up my fifth wheel trailer.



by:

1 year of use and no regrets. Phenomenal tonneau cover and it was so easy to install I did it in the dark. This is my 2nd truck that I have installed a BAK product on and I am completely satisfied.



by:

it was a hard pill to swallow $1200, but all I can say it was well worth it. A full-time RV with a truck camper so every time I move, I have to roll back the cover, but it’s so easy to do and it is very watertight no water ever and I’ve been through two hurricanes this last year, and my truck bed has stayed dry



by:

Great cover. Easy to install. I like the ability to set objects on top of the topper without worrying about damage. My only dislike would be how hot the components get in the direct FL sun. It could easily burn your hands when rolling the cover up to its retracted position.



by:

Mostly a great cover. I've had this cover on my 2021 Ram 8' bed for 1 year. Install took about 45 minutes. There are 2 issues. After snow or rain and temperatures drop below freezing the cover's locking system along the rails freezes making it very difficult to open or close. You have to go the rails and pull the mechanism free. This year I will try WD 40 prior to the winter season to displace moisture.

2nd, issue two of the hinged supports in the cover separated after being rolled up during a several day trip. One about 3 months ago the second 2 weeks ago.The first one was mostly cosmetic. The second separation would not allow the cover to close without forcing it. I contacted BAK and they quickly opened a warranty claim. After sending them photos and a description of the problem they sent a replacement cover. The 5 year warranty is a pluse. Hopefully this is a one off issue. If I have the issue again I will ask for a different cover.



by:

I had these mirrors (same brand but different model) for my 2016 Silverado and used them for the past 8 years when towing our camper. They installed easily and quickly and were also easy to remove until I needed them again. Since getting a new Silverado I opted for these type of mirrors again. I test fit these new ones and again they go on and off easily. I anticipate them holding up as well as my old ones



by:

I’ve had this for a year now. The good: Very nice product, I recommend it. The rollaway ease is great - quick, easy, compact and reliable during near every day use. Effective watertight (not water proof) seal. Definitely recommend the rugged vinyl of the X4 over the X2.

The not so good: the ribs can get kinked and are hard to work back into position when they do. This was really only an issue during initial install, so just be cautious to avoid letting it bend the wrong way. The plastic end caps on the lock rail can pop off, so I recommend using adhesive to hold them firmly in place.

Overall it’s great. Definitely recommend.



by:

It is still in great working condition looks the same as of the day I received the product besides the pollen and it came off of a 2019 gmc 3500 and it on a 2024 gmc 3500 truck now fits perfectly and no leaks very impressed with that when everyone said it not work not at etrailer. They gave me the thumbs up to try it thanks for your time



by:

This is my second BAK cover. I had the flip before this one. I definitely prefer this roll up style as it is much easier to open/close and not nearly as heavy. It would be 5 stars except for the fact that I have to constantly re-adjust and pull the cover back towards the tail gate. It seems to slide forward a micro amount with each opening. So after a few weeks of opening and closing there is a small gap between the tailgate and cover so I have to move it back to seal the gap. Otherwise love this cover.



by:

I use it for my business and it works with a ladder rack. Only complaint is that the little plastic ends that keep falling off. I drilled and put bolts in them to keep them on.



by:

just arrived today got it installed so far it is just what i was looking for.



by:

I like the low profile the easy install and it keeps everything dry. Still looks great after one year.



by:

Fit is a little tight at the latch end even after removing shims, but overall very nice and sturdy. There was some minor damage to the product when it arrived, but nothing that impacted its function or outward appearance. Much nicer than the Revolver (old name) that I had on my last truck.



by:

Love the streamlined fit and added security of this cover. After one year I experienced the same issues others had reported. The hinges used for rolling the cover came separated and caused the closure of the cover to be extremely difficult. Also started to have the vinyl covering separate from metal frame. Thankfully BAK industry stands by the product and replaced the cover under warranty. New cover was shipped for free and already installed. Not 100% waterproof but acceptable trade off for the added protection of aluminum cover. Hopefully the issues with the hinges have been resolved but still have a 5 year warranty.



by:

This is by far the best tonneau out there and BAK is one of the best companies I have ever dealt with. My cover arrived with a broken plastic corner at the tailgate end, I called BAK and without any questions, they sent me the part I needed and also extra ones for both sides. I couldn't be happier.



by:

I am very happy with the purchase 1 year later. I have a 21 Honda Ridgeline and found the instalation easy. You need to install the included sidewalls to accommodate the ridgeline bed shape and they do create an extra seam, but its not an issue. I can still access the trunk. Works well.

  • What Ladder Rack do You Recommend for My Tonneau Cover on a 2021 Ford F-150?
    I have a great ladder rack solution for you. When considering ladder rack compatibility, there is one key aspect to consider: whether the ladder rack mounts onto the truck's bed rails. The reason why this is a deciding factor is because bed rails are used to install most tonneau covers. If you ladder rack interferes with the bed rails, then either the rack or the tonneau can be used at a time (not together). For this reason, the Thule TracRac TracONE Ladder Rack w/ Cantilever - Fixed...

So with that out of the way, we can get into ladder rack and tonneau cover options for you. I have a premium option listed below and a more budget friendly, though still very nice, option below that.

    You're welcome Chad, and I'm happy to help. Starting off with the ladder rack, you're going to need the Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever # TH43002XT-508EX.

  • What Ladder Rack do You Recommend to Use with the Revolver X4s # BAK56ZR on a 2022 F-150?
    As far as the Thule rack, I believe you are referring to the Thule TracRAC SR # TH43002XT-508. You are definitely correct that this works with the BAK Revolver X4s # BAK56ZR. However, it is important to note that since the uprights of the TracRAC SR angle inward toward the truck, there may be some slight rubbing of the X4s against the uprights when opening and closing.

You'd just reverse the process of putting the cover on, and undo the mounting hardware of the cover before removing it.
