Clamps to factory bed rails with included hardware; typically installs in 30-45 minutes with no drilling required.
Product Overview
The BAKFlip MX4 (GEN 3) is a four-panel hard folding tonneau built from heavy-duty aluminum top panels and side rails, reinforced with high-density polymer cores for a 22 percent strength increase over the original MX4.
A patented auto-latching system secures the cover when closed, and re-engineered lock components resist 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 for a clean profile and finishes in textured matte black across all surfaces.
