Get the advantages of both a hard tonneau cover and a soft tonneau cover for your vehicle with the Revolver X4. 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 X4, 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.

Strong, Convenient Hybrid Design

Fully installed coverPartially rolled up cover

The secret to the Revolver X4'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 X4 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 X4 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 X4 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 X4 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 X4 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 X4 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 X4'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 X4 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 X4 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 X4 rails are installed squarely on your truck bed.

Video Transcript for BAK Revolver X4 Hard Tonneau Cover Review

Speaker 1: Today we're going to be taking a look at the Back Line of the Revolver X4 Hard Roll-Up Tonneau Cover offering aluminum and vinyl construction on a matte black finish.Now here's what your covers going to look like installed. As you can see, it's got a really low profile, really slick appearance to it, so it's not one of those that are going to have the bows or the arches or the thicker pads that come up on top. Not really gonna change the exterior look of your vehicle much at all unless you're looking down into the bed.Now typically these are used to either protect items in the back of the truck or secure 'em. Either you've got tools, a fifth wheel, a goose neck. Now the security aspects gonna come with a locking tailgate. Once your tailgate's locked, you're not gonna be able to access the release handles to roll the cover up.

The protection aspect comes from the fully sealed cover, along the back, down the sides and in the front. We've got seals to help prevent any moisture, dirt and debris from getting inside the bed on the items you're trying to protect.Now the top coat of our Tonneau is going to be a UV resistant vinyl so for years to come, we're not going to have to worry about it cracking, fading or deteriorating. The layer below that is aircraft grade aluminum. It's nice and thick, it's going to give this a really good durability and we won't have to worry so much about things coming down on top of it and stuff like that causing any kind of damage or any kind of rips.Now to roll your cover up, you want to open the tailgate there and on each side, there's a little black cable here. You'll pull down on one side, it doesn't matter which and you'll see that's going to release our cover to come up and this really only takes one person.

Just begin to roll it up. The thing I like about it unlike a standard soft cover, it keeps itself square as we roll it up, so we don't have one side smaller and one side kind of getting much bigger.This is also a lot easier to use, especially if you've got a truck like this with the 8 foot bed, then the one with the folding sections. Those tend to get pretty heavy. This doesn't gain a lot of weight as we roll it forward, and that's gonna give you a good look at those interlocking aluminum slats that are there on the bottom. You'll see we get great security on our items, kind of touching on that again.

At the end of each of the slats, you've got an area where the latch on the side is going come down and it engages. So, each and every panel is secured down to the bed of the truck.Now when fully rolled up, you'll notice we still have a good view out of the back glass. Our third brake light's not been obstructed and if you're going to use that camera in the back maybe hooking up to a gooseneck or fifth wheel. You'll still be able to see down to your items.Now there are roll-up style covers similar to this that slide into a storage box. They kind of coil up inside of a box located here.

Well that's a good design, there's really nothing wrong with those covers. Without that canister sitting in here, we have more room in our bed for additional items or if even the back box too which this cover is compatible with, you could add that in there to give you additional storage options.You see, they've also added protection around the entire cover as we roll it up. This allows the cover to rest on the top of it on the softer material, rather than it being on the harder aluminum.Now in the event you we're to roll your cover up too quickly or something or maybe you didn't remember to strap it down and you hit the brakes, if it does roll up to the back of the vehicle, you can see we've got the pads in place and that's gonna give us protection, so we don't have to worry about any contact between the cover and the cab of our truck.Now located on each side, we're gonna have straps with our clip so we can bring over the cover and clip in place to keep it secure. Now these clips are going to be a little bit more difficult I think anyway to get in place than the prop rod that you're gonna get with the back flip or you know the retracts, it's just gonna slide into a container. So I think this is a little bit harder process than what you're gonna see on those other two. But once we do have it cinched down, as you can see, it holds it nice and securely.Now with the cover in this position as you can see, you're free to pretty much load your bed as full as what you did without a cover installed. You're gonna lose, this is the eight foot long version. It takes up about 9.5 inches of space from the front bulkhead. The 6.5, 5.5 foot version should be a little bit smaller than that and the rails that we have installed on each side, those come in from the bed rails about 2.5 inches. So just keep in that mind, make sure that's gonna allow you enough room to get whatever items in that you'll need.And then when it's time to put our cover back in place, we've got the same situation. Just a real easy, one person job here, nothing to align really side to side and we'll just pull down firmly here on the corners with both hands. We hear it latch into place and then we can close our tailgate. Now the nice thing about the way this Tonneau cover operates, it doesn't have anything in the instructions about you have to close it with the tailgate open, you have to close it with the tailgate closed. So you're able to just open the gate, get your stuff in and out without having to release it. But if your tailgate happens to be up, it latches just the same way.Now something I like about the new Revolver X4 that we didn't really see with the X2 is that the side rails here are really matched very well with the OAM bed rails and caps so it gives it a real seamless kind of streamlined look.Now the cover offers a drill free installation. It's a really straightforward and pretty easy process to do. We'll just have a seal that goes across the front here and then four clamps for side on the long bed and usually three clamps per side on the short bed.Now honestly the same could be said for most Tonneau covers, they're usually not that hard to install. Something that does stand out on this cover though that I really like is that we don't have any seams. We don't have any stitching. We don't have any hook and loop fasteners we need to deal with. We're not going to be pushing down the side, going down each side. We're not going to have to worry about seepage through those seams getting into the bed of the truck.And there's another nice feature. Since this does sit inside the rails of our bed, we'll still have full access to our stake pockets for accessories we might want to use.Now based on our experience here in the shop with the X4 and customer feedback, you're going to get a really high quality cover. It offers superior protection for anything that you've got in there. Superior security and all of that comes from a product that's made right here in the United States.And that's going to complete our look at the Back Line of the Revolver X4 Hard Tonneau Cover.

Review from a similar Revolver X4 in Tonneau Covers

Installed myself in less than an hour and a half. Helpful video for installation. Quality fit and finish. Matte finish matches side and rear of Ridgeline bed exactly for a seamless look. Subject to torrential rains (Florida) , minimal water intrusion. Suggest lite lubrication of retaining brackets to side rails for easier positioning during installation. 690636

Review from a similar Revolver X4 in Tonneau Covers

The top is very nice looking and the installation was very easy. The product was engineered well to fit my truck beautifully. Two issues though...it came with some minor scratches and it leaks at the front corners. 494765

Thanks for the review and follow up William. I have checked with my contacts at BAK and to prevent leaking in the front corners they advised to make sure that you have the bulkhead seal installed. That is available as an individual Part # PARTS-326A0004 if you need it. Tonneau covers are intended to be water resistant, and some leaking can still occur.

Review from a similar Revolver X4 in Tonneau Covers

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! 512468

Ive had this tonneau cover for a year now, and I can say that Ive been 95 happy with it. I have just two complaints with it: 1- The rubber strips that cover the length of the bed rails have lifted at the cab side, and depending on how it rains, water just pours in where those strips have lifted. I do have the full bulkhead seal installed, its leaking past that point. 2- The rubber strips have also begun to bubble up randomly along the length of the cover, so I also get water dripping in from along the sides. I have to carry my items in plastic tubs with lids, because the water doesnt just drip down, it will occasionally run along the underside of the cover and drip down towards the middle. The structural aspect of the cover held up to snow without a problem, and I love that its a rigid cover, however, the water leak aspect []s it from a 5-star to a 4.5 star.

  • Ladder Rack Recommendation for 2010 Dodge Ram 6.5 ft Bed with Back Revolver Tonneau
    The best ladder rack option for your 2010 Ram 6-1/2 ft bed with the Bak Revolver part # BAK79213 that you mentioned is the Thule TracRac SR part # TH43002XT-501. This ladder rack fits into the top of the bed rails through the stake pockets which allows room for the Bak Revolver to fit. The Revolver is actually the only tonneau that fits with this ladder rack too. I attached review videos for both of these for you to check out as well.

  • Tonneau Cover to Fit 2014 Ram 1500 6.5 ft Bed with Thule TracRac Sliding Rack
    The only tonneau cover we can recommend for use with a TracRac sliding ladder rack is the Bak Revolver cover as it's the only one that's narrow enough to fit with the ladder rack. The Pace Edwards you mentioned would not work with a ladder rack. So what you'd need is the Revolver tonneau part # BAK79213 and the TracRac # TH43003XT-501 and you'd have a ladder rack and tonneau cover combo that would fit and work well on your 2014 Ram 1500 6-1/2 foot bed.

  • Trouble Installing the TracRac SR with a Tonneau Cover on a 2014 Ram 2500
    The bed rails on your 2014 Ram 2500 may not be perfectly straight but they will still allow for the use of the Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43003XT-501EX. The problem is that they are fighting for the same space they need to be parallel with the Access Lorado Soft, Roll-Up Tonneau Cover part # 834532001767.
