The BAKFlip MX4 (GEN 3) is the next evolution of the industry's most popular hard folding truck bed cover. Re-engineered for superior durability and security, this low-profile cover features heavy-duty aluminum top panels reinforced with high-density polymer cores, offering a 22% increase in strength over previous generations.

When you need full bed access, the panels fold upright against the cab, protected by premium rubber bumpers and held securely by improved prop rod clips.
