I can't tell you how good it feels to see other trucks, pulling up next to me, spending time looking at my cover.

Got a bak roll-x for 2014 Silverado when I bought it new in 2014, had it until I just traded for my 2021, the cover still looked great and worked flawlessly, this revolver x4s seems like a great evolution of the product thus far

Very happy with the design and function of this cover. Like the fact it seals up from water, dust, and that it locks. So easy install. Took me longer to open & remove contents of the box than it took to install, about 20 min tops.

A significant improvement in design over the X4. No more inside cloth sagging from the glue heating up. The rear corners are beefed up. The all-black style inside and out looks great.
