Protect your valuable cargo with the Revolver X4s Tonneau Cover from BAK®. With several upgrades and new features, the latest iteration of BAK’s highly popular Revolver X4s improves upon an already effective design.

While still constructed from durable marine-grade vinyl stretched atop heavy-duty, interlocking aluminum slats, the new BAK X4s features full matte-black styling that extends to all other components. These include the cover's mounting brackets, clamps, hardware, and the undersides of the aluminum slats. Whether open or closed, the Revolver X4s is stealthier than ever.

The new Revolver X4s receives improved weather resistance from a heavy-duty, integrated bulkhead seal, flat side rail seals, and redesigned rear corner caps—all of which ensure the flattest, sleekest, and most weather-resistant truck bed cover on the market.

Patented rotational locking rails and an easy-to-use locking mechanism make for an intuitive experience, allowing simple one-handed operation from either side of the tailgate. This new latch setup also ensures maximum security, preventing thieves from prying open the sides of the cover, slicing open the aluminum top, or accessing the latch mechanism with the tailgate closed.

Installing the BAK Revolver X4s is quick and easy thanks to BAK’s no-drill, clamp-on mounting system.
