America's #1 Selling Hard Folding Cover

America’s #1 selling hard folding cover, the BAKFlip MX4, has new features, including matte-finished cab corner caps, clamps, and elevator bolts for a more streamlined look and feel. Other MX4 features include an enhanced functionality with pre-molded, die-cut, shock-absorbent bumpers and secure prop rod clips.


This heavy-duty, all-season truck bed cover is designed to perform in extreme conditions. MX4’s resilient infrastructure is for everyday use, featuring NEW upgrades to the prop rod clips, rails, elevator bolts, and the A-panel and B-side bumpers that provide enhanced functionality and a more complete matte-finish look and feel. The MX4’s solid and robust design is flush mount, and backed by an extended 5-year warranty.
