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.

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 - BAK88ZR

Average Customer Rating:  4.5 out of 5 stars   (73 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:

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:

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 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:

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:

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:

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:

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:

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:

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:

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.



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:

Some of the hardware didn't quite fit, needed to change bolts. Otherwise, excellent. Have now been using it 7 months... love it.



by:

would have given it a 5 star rating ... BUT ...on a VERY windy day in Kansas ... somehow the cover bowed enough to slip out of the latch rail ...very strong side-wind & it was seen floating up & down in my rear view mirror ...I quickly pulled over to secure it! The small rear corner plastic seal was lost and the other later became so warped in the summer heat it was unusable - after an extended period of being in rolled /stowed position! So now I get a wet rear bed liner when I drive through rain & the carwash ... but as my one initial experience with the customer service was not great I have not followed up on trying to get replacement parts! I use black gorilla tape to seal the rear corners! Othe than that -I really like the security for my truck bed contents, the ease of use ease of install and I just double check the latch (& rail alignment) by thumping it upwards each side before closing tailgate ...no more issues with side-winds!



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:

The cover was delivered fast and in great shape. I have used it for a year and it has preformed great. Would highly recommend.



by:

Honest 1-year review. I like the cover but have issues with it. First, let me state the cover is very nice and does a great job as a cover. But if you have motorcycles like I do the cover presents a challenge when trying to haul them in the back of my truck. There is no easy way to take it off and it's a real pain in the butt. I've found one of my bikes has a fender and doesn't fit under the cover and will rub it if I try. The only solution is to remove the cover and it's proven to be a pain in the butt. So more often than not I do not use the truck with this cover on it to haul my motorcycles. I also don't like how the rubber edge strips just project a few extra inches past the front of the cover. Another thing is the cover is unusable if there is ice on it. You can't roll it up unless you melt all the ice so if you needed it in a pinch and store your truck outside like me you'll find removing the cover with ice on it to be a nightmare. But other than that the cover has been very good. I'd give it a 4 star rating for everyday use but when it comes to hauling motorcycles or winter use I'd give it a 3 for not having a quick-release feature and making it difficult to remove.



by:

The Revolver looks clean and is very secure. I get compliments on it all the time! Been installed for just over a year now and still looks great!
Customer service is top notch!!
I love the videos guys. They answer so many questions and help you decide. Thank you for taking the time to make all of them. Smartest thing ever!!!



by:

This item was forwarded to BAK for fulfillment / shipping - Looks like I am going to wait a month or so for delivery - Probably not etrailer's fault but certainly frustrating -



by:

Great cover overall. Let's just a tiny bit of water through, super strong and tough.

My only complaint - at the very end near the tailgate, occasionally the joint between a couple of the slats pops out. You can still use it like this, but it looks like there's a bump in the cover. Takes a little bit of effort to pop it back in.



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:

I was able to install this cover, with help from a friend, on my 2015 Chevy Silverado 6.5' bed in about 45 minutes. Everything aligned perfectly, it closes smooth, seals well, kept out the rain from a torrential rainstorm the next day. The matte finish on the vinyl matches the plastic on my truck, and doesn't look cheap like most other covers. I love the low profile between the rails look, the truck looks like their isn't a cover on until you get above the bedrail. Totally happy with this product!

  • What Ladder Rack is Compatible with a BAK Revolver X4 on a 2020 Jeep Gladiator?
    I have an alternative for you. Unfortunately, since the Yakima HD-style racks install inside the bed's rails, they are not compatible with BAK Revolver X4s Hard Tonneau Cover - Roll Up - Aluminum and Vinyl # BAK88ZR on a 2020 Jeep Gladiator. For a great alternative ladder rack that will allow you to use your BAKFlip MX4, I recommend the Adarac Pro Series Custom Truck Bed Ladder Rack - Aluminum - Matte Black - 500 lbs # A38ZR. Since the Pro Series ladder rack attaches in the stake pockets,...

  • Recommended Tonneau Cover for 2020 Jeep Gladiator with RCI Bed Rack
    We do not offer RCI bed racks, so it's not something we've tested but from looking at it, it's likely that you could make the BAK Revolver X4s Hard Tonneau Cover - Roll Up - Aluminum and Vinyl - Matte Black # BAK88ZR work. It's not going to be a perfect solution because of the design of the RCI rack though, and I do believe there will be trouble rolling it up.. With that said, I think you'll have the best results by using a retractable tonneau cover like the Pace Edwards JackRabbit Retractable...

  • Recommended Black Ladder Rack For A Black 2022 Jeep Gladiator
    We definitely have options available for a ladder rack on your 2022 Jeep Gladiator. As you mentioned possibly wanting to put a tonneau cover on, I will have options for both. To start with one that will not be tonneau compatible, the Thule Xsporter Pro Truck Bed Ladder Rack - Black # TH500XTB will be a great option. This is rated to carry up to 450 and as long as you do not have the bed rail utility track system, this will fit without issues. The somewhat boxy design and black color of...

  • Are Yakima HD Track Adapters # Y75RR Required to Install OverHaul Ladder Rack On 2021 Jeep Gladiator
    If you are wanting to install the Yakima OverHaul HD Adjustable Truck Bed Ladder Rack # Y01151-58 on a set of Yakima 60" HD Tracks # Y74MR then you will need to use the Yakima HD Track Adapter Kit # Y75RR. Those are needed since you are going to have the BAK Revolver X4s Hard Tonneau Cover # BAK88ZR which is mounted on the inside of the bed rails where the Overhaul would typically mount.

  • Will Yakima OverHaul HD Fit 2023 Jeep Gladiator With BAK Revolver X4s Hard Tonneau Cover
    The BAK Revolver X4s Hard Tonneau Cover # BAK88ZR doesn't come with rails that have T-slots so I'm not entirely sure what you have on your 2023 Gladiator. The cover is compatible with the TS Rails for TruXedo Elevate Rack System # TH25FR. If these are the rails you have on your Jeep then you can use the Yakima OverHaul HD Adjustable Truck Bed Ladder Rack # Y01151-5855.

  • Black Ladder Rack that Fits 2020 Jeep Gladiator with BAK Revolver X4s Tonneau
    The Adarac Pro Series truck bed ladder rack part # A38ZR is a confirmed fit for your 2020 Jeep Gladiator, is black, has a 500 lb weight capacity, and is compatible with tonneau covers like the BAK X4 part # BAK88ZR that fits your 2020 Jeep Gladiator. This would be a great rack that fits everything you are looking for.

  • Are There Any Tonneau Covers for a 2020 Jeep Gladiator With Built-In Crossbars
    I do have some great tonneau cover options for a 2020 Jeep Gladiator like the BAK Revolver X4s Hard Tonneau Cover part # BAK88ZR which is what I recommend. That said, none of which have any way to integrate crossbars. Therefore, your best option for this would be a roof rack like the Thule WingBar Evo Crossbar System (Hard Top Models Only) part # TH711520 and part # TH65BJ.
