BAKFlip MX4 Tonneau Cover for Ford F-150
Our BAKFlip MX4 for Ford F-150 delivers rugged protection in a sleek, low-profile design. This aluminum hard folding cover shields your cargo from weather, theft, and UV damage while maintaining full bed access. The four-panel folding system lets you open partway for tall loads or fold completely against the cab for maximum hauling flexibility.
Each panel is constructed from lightweight aluminum with a matte finish that resists scratches and fading. Heavy-duty aluminum support struts and stainless-steel hardware ensure the cover holds up season after season. Installation takes about an hour with basic hand tools — no drilling required on most F-150 models from 2015 to present.
What makes the MX4 stand out
Aluminum construction built for the long haul
We chose marine-grade aluminum for every panel and crossbar because it delivers strength without bulk. Each of the four panels weighs less than 25 pounds, so you can fold or remove sections by hand when you need to haul a ladder or lumber. The matte powder-coat finish resists UV fading and holds up against highway grime, tree sap, and salt spray.
The same aluminum crossbar architecture used across our BAKFlip MX4 lineup means consistent fitment and long-term durability. Stainless-steel clamps and hinge pins eliminate rust at attachment points. We’ve tested the cover in freeze-thaw cycles, direct sunlight above 120°F, and torrential downpours — the finish stays intact and the hinges stay smooth.
Four-panel fold for partial or full access
Fold one, two, or all four panels
The MX4’s four-panel design lets you customize how much bed you expose. Fold the first panel back for access to the front quarter of the bed. Flip two panels to reach midway. Fold all four panels against the cab to haul tall cargo or a dirt bike without removing the cover.
Automatic latches lock each panel
Each panel latches automatically when you close it — no fumbling with separate locks or straps. Spring-loaded strikers engage stainless-steel receivers built into the bed rails. To open, pull the release handle at the tailgate and lift. The tailgate seal runs the full width of the bed, so water and dust stay out even during highway rain.
Installation and bed liner compatibility
Most F-150 owners finish installation in 60 to 90 minutes using a socket wrench and torque wrench. The rail system clamps directly to the top of your bed rails — no drilling into the truck body on 2015–2024 models. If you’re running a spray-in liner, the clamps sit above the liner lip. Drop-in liners work as long as the liner doesn’t extend past the bed rail height.
Adjustable clamp spacing accommodates slight variations in bed width, so the cover sits centered and seals evenly. We include all mounting hardware, hex keys, and a printed installation guide. If your F-150 has an existing bed rail system or toolbox, check the compatibility chart in your manual — some setups require removing third-party rails before installing the MX4.

Common questions about the MX4 for F-150
The MX4 is compatible with Ford’s factory bed divider as long as the divider sits below the top of the bed rails. If you have a factory toolbox or aftermarket crossbed toolbox, you’ll need to confirm the toolbox height doesn’t interfere with the cover’s panel fold. Most low-profile toolboxes under 12 inches tall work fine, but check clearance before ordering.
Yes, you can safely drive highway speeds with all four panels folded against the cab. The panels latch securely in the upright position and won’t flap or shift in wind. We recommend checking that the panels are fully latched before driving. Some drivers use bungee straps for extra peace of mind on long trips, though the latch system alone is rated for highway use.
The MX4 is rated to support up to 400 pounds when the panels are closed and latched. You can stand on the cover to load roof racks or tie down cargo, but distribute your weight evenly across multiple panels. Walking on a single panel or placing concentrated weight in one spot can dent the aluminum. For regular bed access, we recommend opening the panels rather than climbing over them.
Most aftermarket LED bed light strips mount along the inside of the bed rails and won’t interfere with the MX4’s clamp system. If your lights are mounted on top of the bed rails or stick up above the rail height, you may need to relocate them before installation. The cover sits directly on the rail surface, so any obstruction in that area will prevent proper sealing.
Wash the cover with mild soap and water using a soft sponge or microfiber cloth. Avoid abrasive cleaners or stiff brushes that can scratch the matte powder coat. Rinse thoroughly and let it air dry. For stubborn grime or tree sap, use a diluted all-purpose cleaner and rinse immediately. We don’t recommend waxing or polishing the matte finish — it’s designed to stay non-reflective without additional coatings.
Our three-year warranty covers defects in materials and workmanship for the aluminum panels, crossbars, hinges, latches, and all mounting hardware. Normal wear from use, scratches from cargo, damage from accidents or modifications, and fading from extreme UV exposure beyond normal outdoor use are not covered. If a component fails due to a manufacturing defect, we’ll replace the part or cover at no charge.
Yes, the entire cover removes in about ten minutes once you loosen the clamp bolts on each side. The rail system stays attached to your bed, and the cover lifts off as one assembly. Most owners store the removed cover in a garage or shed. Reinstalling takes another ten minutes — just slide the cover back onto the rails and tighten the clamps. This makes the MX4 a good choice if you occasionally haul tall equipment but want a cover the rest of the time.
