The Revolver X4s gives you the toughness of a hard cover and the flexibility of a soft one. Aluminum slats hidden under a single layer of matte black vinyl create a rigid shield that can hold up to 400 lbs of evenly distributed weight. When locked, the slats interlock along the side rails so the cover can’t be pried up or cut through like a typical soft cover. Close the tailgate and everything inside stays secure and out of sight.
You don’t need clamps or tools after installation—just roll it out, press down on the rear slat, and it locks automatically along both sides. To open it, drop the tailgate and pull either release cord. The latches retract, and the cover rolls up evenly in seconds. Built-in straps and rubber bumpers keep it secure behind the cab without touching the paint, so you can drive with the bed open when hauling tall gear.
A double-coated, reinforced vinyl top and weather seals block rain and dust without using drain tubes. The self-tensioning frame keeps the surface tight, even in heat or cold, so water sheds off the beveled edges instead of pooling. Whether it’s snow, sun, or a car-wash blast, the Revolver X4s keeps your bed dry and your gear protected.
The cover sits only 1-1/2" above the bed rails for a low, streamlined look. The matte black vinyl and aluminum underbody blend in with the truck’s lines instead of standing out. Every part of the cover—from the rail caps to the bulkhead seal—carries the same uniform black finish for a simple, consistent style that looks sharp and stays that way.
Mounting the X4s takes just a wrench. The frame rails clamp inside the bed rails—no drilling required. Slotted brackets and pre-installed shims make alignment easy, keeping the rails square for a snug, watertight fit. Once it’s tightened down, you’re ready to roll up, lock down, and put the cover to work.

Hi everyone, it's Evangeline. And today we'll be taking a look at the BAK Revolver X4s, a premium tonneau cover. So we'll take a look at some of its specs and measurements right here at etrailer.com. So this has the best of both worlds. It looks and works like a soft tonneau cover but then you have the benefits of a hard rolling tonneau cover. So we'll talk about how that works.
And then you can see on our individual pages here at etrailer if it fits your specific truck. So if you're familiar with the Revolver X2, this is going to be the upgrade. And you can tell because of its matte black finish. So if you see something like this driving down the highway, you'll know that it's the Revolver X4s. This is extremely low profile.
So we have this installed on our 2022 Ford F-250. The installation is gonna be different depending on your truck. But if you're curious to see how it works, you can check that video out here at etrailer. But see here on our truck bed how much rise we have, pretty much none at all. Let's take that measurement.
So you can see here how our rails go up here. And then we have the tonneau cover itself being the highest point. And even at its most high point, it's barely a quarter of an inch above our truck bed. So the rail itself is gonna be two inches out. So even that doesn't decrease your actual usable space.
So speaking of flush against our vehicle, notice the way this sits right up at our tailgate. So if you have your tailgate closed you also close the access to your tonneau cover. Awesome if you have important items inside and you wanna keep them secure. And when you wanna open up your tonneau cover, you just open up your tailgate and then you are able to open up that latch. When you got whatever you needed, go ahead and slam your tailgate on it. Just like that, you can see how everything is low profile and flush. So you can actually close this with your tailgate open or your tailgate closed. The way this works is we have that latch system. You just pop them into place, push down. You are gonna have to latch it on both sides. There's also gonna be a string over here which allows you to open up that latch on both sides. So if you're accessing it from the passenger side or the driver's side, you just pull that string, pop right open. So this just rolls along on the rails. So when you're unrolling it, you just bring this back in and it pops into those brackets. You lift it back up and it continues to offer you access to your truck bed. So this creates a very smooth cover on top of your truck bed. So you can see how it blends a soft tonneau cover with the benefits of a hard tonneau cover, like a soft tonneau cover you have that nice matte black finish, but with it blended with the aluminum you actually have 400 pounds of weight capacity evenly distributed on the cover itself. And that also solves the issue that soft tonneau covers have. Some of them, you just rip open that vinyl and people could get access to your cargo on the inside. Since this is hard all throughout, they have that security feature there and you feel better about whatever you're storing in your truck bed. Now, what if it rains or pours or snows Well, you can see here with the rubber seals on each side it creates a weatherproof cover. So with that rain coming down this will drain on the inside, or it will go down the cover, down the rails and right off of your truck bed. Make sure to have everything sealed on the inside. This does not include drain pipes because really, water shouldn't be getting inside in the first place. This rolls up all nice and neat against your bulkhead. You do have straps to secure in the open position. So those secure right up there and then you can see here as well that this does not take up any space underneath or inside of your truck kit. So compared to canister style tonneau covers where they roll up underneath the bed, this one goes up on top. So let's take some measurements to see how much height this is gonna add. Now this will be a little different depending on the truck you have that's installed on but on our F-250 that's pretty much how much height it's gonna add which is from the top of our bed to the top of the roll is eight inches. So if you have a longer bed, it might be a little bit more but still very low profile for a rolling tonneau cover. So this is the style of strap it's gonna use to secure the tonneau cover. I personally prefer something a little bit more secure since this is a metal buckle. So just make sure to tighten down both sides. That way there isn't any movement of the cover itself as you drive around. Having it rolled up like this is also a perfect way to see how we have those different layers. So this is the flat design, which allows you to roll this up and still maintain the hard tonneau cover benefits but still have the soft tonneau cover maneuverability. Then you can also see the rubber seal on this side giving it that weatherproof experience. So this is gonna include pretty much everything you need to install this on your vehicle, but there may be some differences depending on your different trucks. So try to check out our fit guide here at etrailer, that way you can see if we've tried this tonneau cover out on your vehicle and show you the process of how it goes. Now, this includes the bumpers. This includes the straps, things like that. What doesn't include, but I recommend adding on is gonna be a 9/16" socket. This may need another socket size or multiple other tools. So check out those instructions. You're also gonna need some measuring tape just to make sure everything is square. And depending on your truck, you may even need some extra shims if things are not aligned for your truck bed itself. So definitely check out whether you have things like a drop-in liner, the length of your truck bed as you use our fit guide to get the best fit for you. So I've installed a couple of different tonneau covers before. So I have some personal thoughts about this one. And the main thing is that this is probably one of the most low profile tonneau covers I've seen. You can see how it's super flush with our rails. And I really like the concept of a soft tonneau cover with the benefits of a hard tonneau cover. Since we have it where it doesn't take up too much room behind your cab, you get the full access to your truck bed. As you can see here, we have a fifth wheel hitch inside of our truck bed, and we still have access to the side of the bed like those slots or those stake pockets to install a ladder rack. So this opens up a lot of options because you don't need to get extra lax. You don't need to worry about security. You don't need to worry about someone seeing your fifth wheel hitch and being interested in it because you have this tonneau cover on top, protecting it nicely, securely and with style. With this right here was a look at our BAK Revolver X4s premium tonneau cover right here at etrailer.com. My name is Evangeline, and I hope you enjoyed the journey..
Ratings & Reviews
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.
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.
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.
Great fit and easy to install
I like its slim profile look and solid top. I highly recommend this cover with the following exception. In cold weather, the top can freeze in its tracks after a car wash or rain. It is then almost impossible to roll up without putting a heater in the bed. This is the only reason I give it 4 stars. I still would buy it again since I don’t roll up the top much in the winter.
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.
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.
Good quality but very overpriced.
I wanted to like it a lot, but it definitely came with some problems. Ive had it installed for about a year and it has been nice to secure my stuff and still have the option of a completely open bed. Unfortunately it required some tweaking and a bed length shim to fit my truck, which was supposed to be custom fit. I also had to recrimp the release cable once, and the rails frequently ice up in the winter, making it hard to open.
Great cover! Easy to install by yourself with no help. I've had this cover for over a year. It has held up great with no sun fade, is extremely durable and has a great seal to keep the weather out of the truck bed. 100% recommend!
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!
I've had it for about a year now. Good quality and provides excellent security to your cargo bed. Freezing temperatures can make it difficult or impossible to roll up, especially after being exposed to wet conditions-then freezing. I've had to go through the heated car wash a couple times in order to thaw it out to roll it up. However, I would definitely still buy again.
Well made, easy install.
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.
Love this cover and after a year no fade and still looks brand new.
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.
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
It works great. However, it was a bit harder than advertised to install.
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.
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.
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.
I am happy to report that after a year of use since I installed it, my Revolver cover is still solid, and in perfect condition. Only once did I have a little trouble opening it due to the locking rails icing up during an extremely cold day. I was able to free it up with minimal effort within a few minutes, and without causing it (or me) any damage.
The cover looks great, keeps the bed dry, and I’ve received many compliments. Also, even with my full 8’ bed, it doesn’t restrict my view through the rear window when rolled up.
Very happy with both the product and the customer service. Originally I was given a ship date and that date changed after the order was placed. I emailed with Lauren and she was great! It was delivered one day ahead of the original time. This is my second BAK Revolver cover. I had the first on my truck for eight years until I sold the truck. The cover is secure, almost watertight, and looks amazing.
Looks great!
Works great, and our camping generators fit under it!
