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.

East to install. Great fit, very durable and easy to operate

Easy to install and a great fit on the bed of the pick-up. As advertised, great looking and very functional tonneau for your truck!



by:

It’s awesome. However one section toward tear of bed separates sometimes. It takes a minute and a second set of hands to reassemble. Has anyone else had this issue?



by:

Carrie’s customer service and the products. I’m gonna be a repeat customer.



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:

Has been on my truck for a year and still looks great and doesn't leak, very pleased with this cover.



by:

As advertised, looks good, had a broken trim piece when I unrolled the cover. CS was excellant. Some of the instructions are missing or confusing. Overall extremely happy with the whole transaction.



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:

Love this cover. It was a bit tricky to figure out how this works as the Honda Ridgeline requires a kit that comes with it so it'll fit. Once this step was completed, the rest of it was not too hard to figure out.



by:

I could not get this tonneau from my disrtibutor thankfuly you guys had one. it was for a customer but they are very happy with the cover!

  • Ladder Rack Compatible With Pace Edwards Ultragroove Tonneau on 2023 Ford F-150 With 6-1/2 Foot Bed
    Hi Ruben; thanks for the question, and while there is one rack for your 2023 Ford F-150 with a 6-1/2' bed compatible with the Pace Edwards UltraGroove Metal Retractable Hard Tonneau Cover # PE66UV, it does not have sides, and is part # TX84NV. There actually isn't a ladder rack with sides compatible with a tonneau cover as those all require bed rails to install. The EL200 has 200 lbs of capacity as well, which I'm not sure is enough for you, so I did want to mention other options. What...

  • Ladder Rack for 2025 Ford F-150 With Revolver X4ts
    Hey Matt, congratulations on the new truck! For the TS rails that come with that tonneau cover we have the Yakima OverHaul HD Adjustable Truck Bed Ladder Rack. Most people get the version with 68" crossbars # Y01151-5855 but if you want 78" crossbars # Y01151-5955 is also available. The adapter lets it ride in the track and makes it easy to install and remove as needed. The height of the rack adjusts from from 19" to 30" and supports up to 300 lbs.

  • Bike Racks Compatible With Adarac Bed Rack & BAK Revolver X4s Tonneau On 2023 Ford F-150 6-1/2' Bed
    Yes, the Adarac Aluminum M-Series Custom Truck Bed Ladder Rack # A62FR is going to be compatible with the BAK Revolver X4s Hard Tonneau Cover # BAK89ZR on your 2023 Ford F-150. For a bike rack it will really come down to which type of carrier you prefer to use. The Thule ProRide XT Roof Bike Rack # TH598004 will secure the bike by the frame and the Thule UpRide Roof Bike Rack # TH599000 secure the bike by the front wheel. Both these racks will secure the the crossbars on your Adarac using...

  • Is BAKFlip MX4 Compatible With Thule TracRac SR on 2022 Ford F-150
    Yes, you can use the BAKFlip MX4 with the Thule TracRac SR # TH43002XT-000. However, you will have to slide the rear upright to be able to clear when you fold the cover since the uprights angle in. This is true for any folding tonneau cover you might add with the TracRac SR. You will need one of the following: -BAKFlip MX4 Hard Tonneau Cover # BAK76FR for a 5-1/2' bed -BAKFlip MX4 Hard Tonneau Cover # BAK46FR for a 6-1/2' bed -BAKFlip MX4 Hard Tonneau Cover # BAK66FR for an 8' bed If...

  • Is There A Tonneau Cover Compatible With A Thule TracRac TracOne Ladder Rack For A 2023 Ford F-150
    Hi Oliver, Since the Thule TracRac TracONE Truck Bed Ladder Rack # TH27000XT mounts to the lip of the bed rails it's going to block all tonneau covers from mounting to the bed. You would need to go with a stake pocket-mounted rack like the Thule TracRac SR Sliding Truck Bed Ladder Rack # TH43002XT-501 along with a cover like the BAK Revolver X4s Hard Tonneau Cover # BAK89ZR, which mounts inside of the bedrails.

  • Base Rails for Thule TracRac SR 2021 F-150 6.5ft bed
    The rails that you'll need for the Thule TracRac SR # TH43002XT-501 for your 2021 Ford F-150 with the short bed is found with part # TH21501. Technically there are other tonneau covers that will fit with the TracRac SR like the folding ones, but the BAK Revolver is the best fit because it's narrower so the rubber seals won't contact the base rails. The X4 that you'll need for this setup is part # BAK89ZR.

  • Tonneau Cover and Ladder Rack with Over Cab Extension for 2021 Ford F-150 6.5 ft Bed
    I checked with Thule and for your 2021 Ford F-150 6-1/2 foot bed we have the Thule TracRac SR Sliding Ladder Rack part # TH43003XT-501EX as a confirmed fit that has a cantilever extension for over the cab of the truck. Then for a tonneau cover that fits your truck and with the ladder rack the best option is the BAK Revolver X4s part # BAK89ZR. Due to how the Buyers Products ladder rack installs it can't fit with a tonneau cover.

  • Can Cover of BAK Revolver X4s Tonneau For 2024 Ford F-150 be Removed Without Taking Off Rails
    Hey David, Yes, you can technically remove the cover without taking off the rails of the BAK Revolver X4s tonneau covers for a 2024 Ford F-150. You'd just reverse the process of putting the cover on, and undo the mounting hardware of the cover before removing it. This will be the same for all the covers that fit the '24 F-150, part # BAK56ZR for a 5-1/2' bed, # BAK89ZR for a 6-1/2' bed, or # BAK29ZR for an 8' bed. Then for a rack that has T-slots, can be used with the Revolver X4s, and...
