BAKFlip MX4 Tonneau Cover for Ford F-150
The BAKFlip MX4 for Ford F-150 is our matte-finish folding hard tonneau cover engineered for owners who demand premium bed protection without the gloss. We built the MX4 with lightweight aluminum panels that fold completely out of the way for full bed access, then lock securely in any position along the rail system.
Our flush-mount design sits inside the bed rails for a low-profile appearance that complements every F-150 trim level. The exclusive FRP (fiber-reinforced polymer) panel surface resists UV damage, denting, and scratches while maintaining a consistent matte black finish that won't fade or chalk over time. Integrated drain channels route water away from your cargo, and our automatic latching system locks at the tailgate with no additional clamps or straps required.

Aluminum Panel Construction & Matte Finish
We manufacture every BAKFlip MX4 panel with heavy-duty aluminum framing and a fiber-reinforced polymer skin that delivers superior impact resistance compared to vinyl or soft covers. The matte black FRP surface won’t show fingerprints, swirl marks, or minor scratches the way glossy finishes do, making it ideal for F-150 owners who use their trucks for work and recreation.
Our proprietary panel design distributes snow loads and standing water evenly across the aluminum framework, preventing sagging or warping even in extreme climates. Each panel connects with commercial-grade hinge assemblies that cycle through thousands of open-close operations without losing tension, and the entire cover weighs just 65 pounds for easy removal when you need to haul oversized cargo.
Flush-Mount Installation & Bed Rail System
The bakflip mx4 f150 installs inside your truck’s bed rails using our clamp-on mounting system that requires zero drilling or permanent modification. We engineered the side rails to sit flush with your bed caps, creating a seamless low-profile appearance that doesn’t add height or wind resistance.
Our patented rail design includes pre-installed drain channels that route rain and snow melt outside the bed perimeter before water can reach your cargo. The installation process takes 20–30 minutes with basic hand tools, and our rail system is fully compatible with most spray-in bedliners and drop-in liners without additional spacers or adapters.
Folding Panel Operation & Bed Access
Partial and Full Bed Access
The four-panel folding design lets you open one, two, three, or all panels depending on your cargo needs. Each panel locks in the upright position with our integrated prop rod system, so you can drive with partial bed access without worrying about panels slamming shut. When you need full bed clearance, all four panels fold completely against the cab and rest on shock-absorbing pads that protect your truck’s finish.
Our automatic dual-latch system at the tailgate engages when you close the cover and releases with a simple twist of the center knob. The MX4 also locks at every panel position along the rail, giving you the flexibility to secure cargo of any height while maintaining weather protection for the rest of your bed.

Common Questions About the MX4 for F-150
Yes, we manufacture the MX4 for all Ford F-150 body styles from 2015 through 2024, including SuperCab and SuperCrew configurations. We offer three bed length options: 5.5-foot, 6.5-foot, and 8-foot.
Each version is engineered for exact fitment on your specific year and bed size, and our rail system accommodates factory bedliners, tie-down hooks, and the Ford tailgate step without modification.
Absolutely. The MX4 uses our clamp-on rail system that requires zero drilling or permanent modification to your F-150.
Installation takes 20–30 minutes with basic hand tools, and we include all clamps, spacers, and hardware specific to your truck model. The rails attach to your bed caps with adjustable clamps, and the cover slides into the rail channels and locks in place with the included hardware.
Our exclusive drain channel system routes water away from your cargo in all weather conditions. The FRP panels shed rain and snow into molded channels along the side rails, which direct water outside your bed perimeter before it can reach your cargo.
Continuous EPDM rubber seals along every panel edge and a perimeter bulb seal block dust and moisture at highway speeds. The matte finish won't crack or peel in freezing temperatures, and the aluminum panel framework supports heavy snow loads without sagging.
Yes, the four-panel design folds in multiple configurations. You can open one panel for items that sit slightly above bed height, two panels for medium-height cargo, or all four panels for full bed clearance.
Each panel locks in the upright position with our integrated prop rod system, so you can drive with partial bed access without panels closing on their own. The automatic latch system also locks at every panel position along the rail for secure transport.
The MX4 is compatible with most spray-in liners, drop-in liners, and tonneau-friendly toolboxes. Our flush-mount rail design includes spacers for common bedliner thicknesses, and the rail system clears factory tie-down hooks and bed lighting.
When the cover is fully opened, the folded panels rest against the cab and allow clearance for cab-mounted toolboxes and fifth-wheel hitches. We also offer the BAKBox 2 fold-away toolbox that integrates directly with the MX4 rail system for additional storage.
The MX4 features a matte FRP panel finish, while the G2 has a gloss finish. Both covers use the same aluminum panel construction, four-panel folding design, flush-mount rails, and automatic latching system.
The matte finish on the MX4 resists fingerprints and minor scratches better than gloss, making it popular with work truck owners. The G2's gloss finish offers a showroom appearance for F-150 owners who prefer a high-shine look.
We back every BAKFlip MX4 with a limited warranty that covers defects in materials and workmanship. The aluminum panels, hinge assemblies, and rail system are warranted against structural failure under normal use.
Our customer service team provides installation support and replacement parts if you experience any issues. Full warranty details and registration instructions are included with every MX4 shipment.
