    The BAK BAKFlip MX4 is a hard-folding aluminum tonneau cover for 1988-2014 Chevy and GMC full-size trucks (C/K, Silverado and Sierra 1500/2500/3500) with the 6ft 6in bed. Its heavy-duty aluminum top panels are reinforced with high-density polymer cores for a 22 percent strength increase over the original MX4, and a patented automatic latching system secures the cover when it is closed. EPDM perimeter seals, tight-fit clamps and a dual-action tailgate seal keep water out, and the panels fold flush against the cab for full bed access. It installs on the factory bed with no drilling.

    FAQ

    What is the BAK BAKFlip MX4?

    It is a hard-folding aluminum tonneau cover with a textured matte black finish for 1988-2014 Chevy and GMC full-size trucks (C/K, Silverado and Sierra 1500/2500/3500) with the 6ft 6in bed.

    Can I still use the full bed?

    Yes. The panels fold flush against the cab for 100 percent bed access, and the closed cover holds up to 400 lbs evenly distributed.

    Is it weatherproof?

    It uses EPDM perimeter seals, tight-fit clamps and a dual-action tailgate seal to keep water out.

    Does it require drilling to install?

    No. It is a one-person, no-drill installation that clamps to the factory bed rails.
