A great tonneau cover doesn’t just cover up your gear, it elevates the style of your entire truck. A great tonneau should look good closed and sealed, but it should also look good while in operation and above all, it should get the job done. Now Bak has done it all with a truck bed cover that delivers style and security in spades, the Bak Revolver X4s Tonneau Cover.

Thoughtfully designed inside and out, your Bak Revolver X4s Tonneau Cover offers a stylish Matte Black look not only on top but also on the Aluminum underbody. Even the installation clamps are Matte Black for a complete and consistent style. The side rail seals are smooth and flat and the rear corner caps add to the refined and sophisticated final appearance.

Heavy-duty safety straps will make it easy to drive at any speed with this truck bed cover in the opened position. The capped aluminum slats ensure safety for your hands while you operate the tonneau. The integrated bulkhead seal will keep your tools and cargo bone dry even in the worst of weather. This cover is made in the USA and backed by a 5-Year Warranty.

Measured out perfectly and installed in less than ten minutes using the Milwaukee rachet to tighten the clamps. the only slowdown was the weather stripping (they provide multiples) in figuring out that some of it won't be used at all.

Love the bed cover. Could be a few slight improvements wo waterproofing the corners, but overall a great product. There was a little tightness around the latching system but once the plastic on the latch wore down it snaps in like a charm.

This product was super easy to install and it looks great. The only quality issue I’ve found on it was the rubber gasket on the side rails wasn’t put on straight. A little annoying, but does not effect the performance.

I really like the cover. Only issue I have is the sharp edges at the tailgate end of the product.

I am very satisfied with this cover, it looks good, performs well and serves the purpose. It is not waterproof, however after a few direct car washes the water inside the bed is very minimal.

The BAK Revolver X4s is an upgrade from my 2010 purchase years ago. The old Revolver had problems with the side felt material coming off after a few years. The new current Revolver X4s has solved that problem, by not using the felt material. I really like the Tonnue cover over the flip design. Very durable and hard cover with very little water penetration. It is my opinion that it is worth the price.

For 2023-2024 Chevy Colorado, you will probably have to shim the rails yourself. No big deal and not worth anything less than a 5 Star Review- just be ready. I just used a penny at each clamp, between bed and rail and it rolled and locked perfectly. Just took some extra time, because instructions didn’t cover that possibility. I’m sure they will fine tune this kit to the new body style. Great cover and I love the way it locks down every inch- not just at the tailgate. A+

This would have taken less time to install, but I needed to shim the rails, in order for the mechanism to lock the cover in place, when closed. Still worthy of a 5 star review- just be ready to shim it. I just used a penny at each clamp. For 6¢ more, this will work flawlessly on your 2023/2024 Colorado. A+ Also, there’s a plastic cap on each side of the cover at the tailgate. Pop it off and apply some clear or black silicone to it and pop it back on. I read reviews on how this pops off and gets lost…. Just fix it now. This is a great cover!
