BAK BAKFlip MX4 Matte Hard Folding Truck Bed Cover | Select 2019-2026 Chevy Silverado/GMC Sierra 1500 (6ft 6in Bed) | 448131

Fits select 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 models with a 6ft 6in bed.

The BAKFlip MX4 (GEN 3) is a premium hard folding truck bed cover engineered for maximum durability and a sleek, low-profile appearance. Constructed with heavy-duty aluminum top panels reinforced by a high-density polymer core, this next-generation cover is 22% stronger than previous versions. Its textured matte black finish is UV and scratch-resistant, providing a flush-mount look that practically disappears into your truck's profile.

Security and weather protection are significantly enhanced in this generation. The MX4 features a patented automatic latching system with re-engineered lock components for better resistance against forced entry. Revised EPDM rubber perimeter seals and tight-fit clamps minimize water intrusion, while an extra-long dual-action tailgate seal allows you to close the tailgate regardless of the cover's position. When you need full bed access, the panels fold upright against the cab, secured by prop rods and protected by premium rubber bumpers.
