BAK BAKFlip MX4 Hard Folding Tonneau Cover - 2017-2023 Ford Super Duty 8ft Bed

This is the BAK BAKFlip MX4 Hard Folding Tonneau Cover built for the 2017-2023 Ford Super Duty 8ft Bed. BAK part number: 448331.

The BAKFlip MX4 is a hard folding cover for owners who want more security than a soft cover gives. Its aluminum panels lock down when closed and fold up against the cab when you need the whole bed, without taking the cover off the truck.

On a heavy-duty diesel that hauls tools all week, a hard cover just makes sense. Close it up at the job site and your gear stays out of sight and out of the weather.

Why we like it

• Polymer-reinforced aluminum panels, rated for 400 lb evenly distributed
• Folds against the cab for full bed access, and your third brake light stays visible
• Improved seals and a drainage system to keep the bed dry
• Auto-latching panels lock as you close them
