When you’re hauling tools or gear, you want a cover that keeps everything protected from rain, dust, or snow without giving up strength. The Revolver X4s combines ¼" thick, aircraft-grade aluminum slats with double-coated, reinforced vinyl for a tough, weather-resistant barrier. Rubber seals and beveled edges direct water off the sides, while the matte black finish resists UV damage and looks clean year-round. It’s strong enough to support up to 400 lbs of evenly distributed weight, so you get hard-cover durability with soft-cover flexibility.
You don’t have to choose between a sleek cover and usable bed space. The Revolver X4s rolls up by hand and secures behind the cab with built-in straps and sturdy buckles. That means instant full-bed access for hauling large items without removing the cover. Because it mounts inside the bed rails, you still have full use of stake pockets for tie-downs or racks. The self-tensioning frame keeps the cover tight and smooth every time you roll it out.
Opening or closing the cover is quick and easy. Just drop the tailgate and pull either release cord to roll it up, or press down on the rear slat to lock it shut. The integrated teeth along both rails automatically secure the cover from front to back—no Velcro, snaps, or adjustment needed. When your tailgate is locked, the cover locks too, so your cargo stays secure.
Unlike bulky covers that sit high above the bed, the Revolver X4s sits only 1-½" above the rails for a clean, flush appearance. The matte black aluminum underbody and smooth vinyl top keep the truck’s lines simple and refined while adding scratch and impact resistance.
Mounting the Revolver X4s takes just a wrench—no drilling required. The side rails clamp inside the bed and feature slotted brackets and pre-installed shims that help them align squarely for a tight, even fit. Once installed, the integrated bulkhead seal and felt-lined slats keep the cover snug and quiet through every mile.
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!
