Built to last and perform flawlessly, the Revolver X2 Truck Bed Cover offers full truck bed access and installs in less than 15 minutes with no drilling required for installation.

The Revolver X2 also features a flush low profile design that looks great, improves aerodynamics for fuel efficiency, and allows you to retain any factory accessories (such as track systems, tie downs, racks, etc) that you already have. Take a moment to view our Revolver X2 demonstration videos and you'll see why this cover is a great solution for your truck.
