BAK 448132 MX4 Hard Folding Tonneau Cover Chevrolet Silverado/GMC Sierra 1500 19-25 8'

BAKFlip MX4

The BAKFlip MX4 is a premium hard-folding truck bed cover that combines sleek styling with robust protection. Constructed with heavy-duty aluminum top panels and side rails, the MX4 resists cuts and slashes and delivers secure, long-lasting coverage for your cargo. Its flush-mounted design and textured matte-black finish integrate seamlessly with the truck profile for a low, factory appearance.

Security and weather resistance are engineered throughout: auto-latching side rails lock the panels in place to deter prying, while EPDM rubber perimeter seals and a dual-action tailgate seal protect against moisture. The cover folds toward the cab for full bed access and features integrated prop rods and strong support clips for stable operation when open.

*Installation and compatibility notes: The MX4 installs using a clamp system designed for no-drill installation; basic tools are typically all that’s required.

For full bed access, fold the cover flush against the rear window and support it with the integrated prop rods and clips. Verify vehicle application and bed size to ensure proper fit before installation.
