Product Details

Constructed primarily from alloy materials, including heavy-duty aluminum top panels and side rails, and reinforced with high-density polymer cores, the new and improved MX4 delivers 22% more strength than the original model. 

Enhanced security features include BAK's patented auto-latching system, securing the cover automatically when closed, and re-engineered lock components to resist forced entry from would-be thieves. You can rest assured that whatever you're hauling, it's safe and secure.  

Enhanced EPDM rubber perimeter seals and tight-fit clamps provide the best possible seal, keeping the elements out. Additionally, a 13% longer dual-action tailgate seal provides increased weather protection for the tailgate and allows for full tailgate functionality, no matter the cover's position. 

No-drill, click-in mounting reduces installation time by up to 12 percent over previous models. 

Best of all, your BAKFlip MX4 Tonneau Cover is Made in the USA!
