Hey, It’s Waylon “Joe” Kite here. I am a West Virginia native and a die-hard pickup truck fan. My story with trucks started with my dad’s 1989 Ford F-150, and it's still going on. I'll share all my trucking experiences (both great and gross ones) with you. I have a garage full of tools to fix and renovate trucks and a freezer full of ales. Do you want to join me?

One of my friends recently asked me to suggest a reliable tonneau cover for his vehicle. And I told him to pick between Bak Revolver X4 and X4S: two outstanding truck covers.

Both the covers share some similar advantages and attributes. But before suggesting to him one of the two, I looked for what differences they have. So what differences are there between Bak Revolver X4 vs. Bak Revolver X4S?

The key differences are Bak Revolver X4S for 2021-2022 Ford F-150 trucks offer sealed four-corners, but X4 for 2019-2023 Chevy/GMC Silverado/Sierra doesn’t. The X4 locks after pushing, the locks automatically. The vinyl overlay on X4 is not correctly attached like X4S as it’s glued well.

It’s not hard to decide when you know the significant similarities and dissimilarities. So, let’s glance at the quick comparison table to help you better understand which one you should select.

Bak Revolver X4 vs. X4S: Key Differences

Despite both the cover being from the same brand, they have some notable differences, such as


Bak Revolver X4

The Bak Revolver X4 features aluminum slats and a vinyl overlay. While aluminum works as a durable blanket that is hard to break and cut, vinyl will protect aluminum from sun rays, raindrops, and dust.

Bak Revolver X4S

This cover features the same materials as the product mentioned above. However, this cover’s vinyl is well attached to the aluminum slats.

As both covers are made of the same materials, you will enjoy the same quality. However, the black revolver X4S is better than X4 because the vinyl overlay is perfectly attached to the aluminum beneath.

Bak Revolver X4

It has a matte finish painted with powder-coated paint to keep the cover tear and scratch-free.

Bak Revolver X4S

Bak’s Revolver X4S has the same matte finish as the model X4. It is also colored with a premium quality powder-coated color.

Both covers have a similar finish and use the same quality powder-coated paint. Both will make your truck bed appealing as they will not tear or get scratched easily.

Safety Features

Bak Revolver X4

The entire cover is made so that when the cover and tailgate are locked, no one can access the truck bed from any side.

The blanket is attached well to the rails and can’t be lifted unless the latches are pulled to release it. To release the latches, one must unlock the tailgate first.

Furthermore, the aluminum slats are sturdy enough to get hit by sharp knives and not get cut. Hence, the chances of a thief stealing things from your truck are reduced. You must push the cover down well and lock the tailgate to lock it completely.

Bak Revolver X4 Safety Features

Bak Revolver X4S

The back revolver x4s is even better regarding the security system. It has an auto-lock, and the four corners sealed system has added more security because you don’t need to push the blanket down to the tailgate.

It will automatically get locked when rolled down to the tailgate. Besides, the corners are sealed well, so if a person tries to cut off the tonneau cover, they will require a powerful cutting machine that uses electricity or a battery.

The two will significantly prevent stealers from stealing your stored stuff, but Bak Revolver X4S will do a better job.


Bak Revolver X4

All the necessary gears you need to install the Bak Revolver X4 cover will come with its package. You can install it without drilling any screws or tightening knobs.

Bak Revolver X4S

The installation process for Bak Revolver X4S is the same as the X4 blanket.

As the installation procedures are similar, you should pick the one specifically made for your truck model.

Which One is Better for You: Bak Revolver X4 or X4S 

Bak Revolver X4 and X4S are two great tonneau cover picks. But you still need to be careful while choosing one. Although they are pretty much the same in appearance and provide many similar benefits, you might select the wrong blanket for your truck.

They are excellent, but you can get the most out of them by utilizing them for different purposes. If your profession is shifting cargo to various places in your city, the Bak Revolver X4S tonneau cover will work the best for you.

It’s most trusted for professional work because the blanket is upgraded with an improved security system and additional strength.

On the other hand, Bak Revolver X4 is the best pick if you are searching for a lower price truck bed cover that will give your stored stuff the ultimate protection. You don’t often keep things over the cover.


What is the difference between Bak Revolver X2 and X4? 

The visible difference that anyone can tell by looking at them is the finish. While the Bak Revolver X4 features a matte look, the X2 has a glossy appearance.

Does the Bak Revolver lock?

Bak Revolver covers the lock with the truck perfectly. However, the locking system varies. For example, the X2 locking system includes a rotational lock. At the same time, X4 requires pushing to attach to the tailgate, and X4S has locked automatically by rotating it to the tailgate.

What are the Bak Revolver X4 problems?

The Bak Revolver X4 tonneau cover is an outstanding piece of cover. However, it has merits as well as demerits.

It’s not waterproof but features a vinyl overlay that keeps your cover less heated under extreme sunlight. Also, the vinyl is not glued well; hence a smaller amount of dust gets access to the truck.

What is the Bak Revolver X4 weight limit?

The bak revolver x4 can take up to 400 pounds of weight on it. You can store things over it that weigh under 181 kilograms.

It can hold heavyweight things like bicycles, kayaks, and similar products.


Bak Revolver X4 and X4S are two popular tonneau covers of the Bak industry. But without proper information, it is hard to decide which to pick for your truck.

Hence, we compared the two truck bed covers. From this Bak Revolver X4 vs. Bak Revolver X4S comparison, now you know which truck models they require and their similarities and dissimilarities.

But in my opinion, Bak Revolver X4S will provide better service than X4 since it’s more durable and upgraded. However, Bak Revolver X4 is the best selection for 2019-2023 Chevy/GMC Silverado/Sierra model trucks.
