Install Difficulty: DIY Possible
Clamps to factory bed rails with included hardware; typically installs in 30-45 minutes with no drilling required.
Product Overview
The BAKFlip MX4 is a hard folding aluminum tonneau built from heavy-duty top panels and side rails reinforced with high-density polymer cores. Panels are 22 percent stronger than the previous generation for improved durability under load.
Security comes from BAK's patented auto-latching system plus re-engineered lock components with better resistance to forced entry. EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep water out of the bed.
The cover sits flush with the bed rails in a textured matte black finish, maintaining factory tailgate functionality in any cover position.
