The BAK BAKFlip MX4 (GEN 3) fits the 2017-2022 Ford F250 Super Duty 8ft bed and delivers a hard folding tonneau with 22% stronger panels than the original MX4.
🔧
Install Difficulty: DIY Possible
Clamps to factory bed rails with included hardware, no drilling required; typically installs in 30-45 minutes with two people.
Product Overview
The BAKFlip MX4 is built from heavy-duty aluminum top panels and side rails reinforced with high-density polymer cores. Each panel is 22 percent stronger than the previous generation.
Security comes from BAK's patented auto-latching system plus re-engineered lock components that resist forced entry better than GEN 2. EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep water out of your F250's 8ft bed.
The cover sits flush with the bed rails in a textured matte black finish for a clean, factory-integrated look.
