Introducing the all-new BAKFlip MX4, featuring heavy-duty aluminum matte finish panels that offer superior UV and scratch resistance, and an enhanced premium density foam core.

Why Upgrade?
This heavy-duty, all-season truck bed cover is designed to perform in the most extreme conditions. The MX4’s resilient infrastructure is designed for everyday use, with upgraded components that provide enhanced resistance to the elements without compromising its sleek, low-profile look and feel. The MX4’s solid and robust design is flush mount, and backed by an extended 3-year warranty.
