The BAK BAKFlip MX4 (GEN 3) fits the 2021-2026 Ford F-150 5.7ft bed, including the 2022 Lightning, and delivers hard-folding security with a flush, matte black finish.
Product Overview
The BAKFlip MX4 is a premium hard folding tonneau cover built from heavy-duty aluminum panels and side rails, reinforced with high-density polymer cores.
Panels deliver a 22 percent increase in overall strength versus the previous generation. Re-engineered lock components and BAK's patented auto-latching system improve resistance to forced entry.
Revised EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep cargo dry while preserving factory tailgate function on your Gen14 F-150.
