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.

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

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.

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!

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?

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

  • Recommended Tonneau Cover And Ladder Rack Combo For A 2019 Ford F-150 5.5' Bed
    Hey Colin, Both the TruXedo Sentry CT Hard Tonneau Cover # TX1597716 and BAK Revolver X4s Hard Tonneau Cover # BAK39ZR are essentially the same cover with just some minor aesthetic differences. Both operate exactly the same and sit on the bed the same way. If I had to choose between the two I'd go with the TruXedo Sentry CT Hard Tonneau Cover # TX1597716 because it sits closer to the edge of the bedrails so you're not losing extra space for the rails. This cover can be paired with the...

  • Sliding Ladder Rack and Bike Rack for 2018 Ford F-150 Truck Bed
    Thule makes TracRac sliding ladder racks that are a fit for your 2018 Ford F-150 which would work well. You'd just need to know the length of your truck bed to pick out the correct part number. If you have a 6-1/2 foot bed you'd want the part # TH43002XT-501, if you have an 8 foot bed you'd want the part # TH43003XT-000, or if you have a 5-1/2 foot bed you'd want the part # TH43002XT-508. Then for a tailgate mounted bike rack the Softride Shuttle Pad part # SR26457 would fit and work great too.

  • Ladder Rack and Tonneau Cover Recommendation for 2018 Ford F-150 5-1/2 ft Bed
    You are on the right track. The only way to fit a tonneau cover and ladder rack in a truck like your 2018 Ford F-150 5-1/2 foot bed will be a Sliding Thule TracRac # TH43002XT-508 plus a BAK Revolver part # BAK39ZR. I attached a picture that I took from the install instructions that shows how the rails attach to the stake pockets for you to check out.

  • Recommended Tonneau Cover and Ladder Rack for 2018 Ford F-150 for Rooftop Tent
    For your 2018 Ford F-150, the BAK Revolver # BAK39328 for an 8 foot bed is an excellent choice for accessibility and function. Unfortunately there is not a rack that is available that is below cab height that will also work with the tonneau cover to allow you to utilize both. You would either be too low to roll the cover or above the cab. We have found the best system with this tonneau to be the Thule TracRac SR Sliding Truck Bed Ladder Rack - 1,250 lbs # TH43003XT-000 which is a fit...

  • Best Tonneau Cover for Thule TracRac SR Sliding Ladder Rack for a 2020 Ford F-150 5.5 Bed
    The correct Thule TracRac SR Sliding Truck Bed Ladder Rack for a 2020 Ford F-150 with 5-1/2' bed is part # TH43002XT-508. In regards to tonneau cover compatibility, the BAK Revolver X4s Hard Tonneau Cover part # BAK39ZR is the best option as it's super durable and fits perfectly. The Thule TracRac SR Sliding Truck Bed Ladder Rack is only offered in silver.

  • Will the Thule TracRac SR Work with the BAKFlip MX4 on a 2018 Ford F-150 5-1/2 Foot Bed
    I do have some options for you but the Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43002XT-508 and the BAKFlip MX4 Hard Tonneau Cover part # BAK48329 are not a good fit. The rails on the SR are rather wide so they would likely overlap with the seals on the MX4. In addition to this, you would need to move the rear rack forward in order to fold the cover up each time and with continuous use the seals on the cover will wear out. The only tonneau cover that we know for sure works...

  • Best Ladder Rack for Use with BAK Revolver X4s Tonneau Cover for a 2016 Ford F-150 Short Bed
    A tonneau cover and a ladder rack can be compatible with each other on a truck such as your 2016 Ford F-150 short bed as long as they do not require the same mounting point for installation. The best combination that is known to be compatible is the BAK Revolver X4s hard tonneau cover # BAK39ZR and the Thule SR Sliding Ladder Rack # TH43002XT-508. The X4 also works with the 3-bar SR rack # TH43002XT-508EX which includes a 3rd cantilever extension bar for over the cab. The Revolver and...

  • Are Thule TracRac SR Ladder Racks Removeable and Compatible with BAK Revolver X4s Tonneau Cover
    Yes, you are correct that the Thule TracRac SR Sliding Ladder Racks are compatible with the BAK Revolver X4s tonneau covers such as # BAK39ZR. And the TracRac SR does allow the uprights to be removed completely from their tracks or moved to your desired positions for specific cargo needs. The TracRacs for your 5-1/2-foot bed 2018 F-150 are the standard 2-bar system # TH43002XT-508 and the 3-bar system that includes an over-the-cab cantilever # TH43002XT-508EX.

  • Can The Thule TracRac Ladder Rack Be Used With A Tonneau Cover On A 2018 Ford F-150
    If you have the Thule TracRac SR # TH43002XT-508, which mounts in the stake pockets of the bedrails instead of clamping to the inner lip then, yes, you can use an inside-the-rails style tonneau cover along with the ladder rack. Since there are so many options with this style of mounting I'd need to know a bit more of what you'd prefer to find the best option for you. That being said, BAK roll-up covers like the BAK Revolver X4s Hard Tonneau Cover # BAK39ZR are the most popular choice...

    The TracRack Sliding Rack is one of the most popular options for a ladder rack because of the compatibility with the BAK Revolution Tonneau cover.

If you have the 5-1/2 foot bed you will want the BAK Revolver X4s # BAK39ZR along with the Thule TracRac SR # TH43002XT-508. If you have the...
