BAKFlip MX4 for 2020-2024 Jeep Gladiator | Hard Folding Tonneau Cover
We built the BAKFlip MX4 specifically for Jeep Gladiator owners who demand serious bed protection without sacrificing quick access. This hard folding tonneau cover fits all 2020, 2021, 2022, 2023, and 2024 Gladiator models with the 5-foot bed, giving you four rigid aluminum panels that fold completely open for full bed use or lock securely for weather-tight cargo protection.
Our matte black finish resists scratches and UV damage while maintaining that rugged Jeep aesthetic. The MX4 installs in about 30 minutes with our clamp-on rail system—no drilling required—and sits flush with your bed rails for a factory-installed look. Whether you're hauling adventure gear to the trailhead or securing tools on the job site, this cover handles desert heat, mountain snow, and everything between.
What makes the MX4 perfect for your Gladiator
Aluminum Construction Built for Jeep Adventures
We engineered the MX4 with heavy-duty aluminum panels that stand up to the punishment Gladiator owners dish out. Each of the four panels features a textured matte finish that hides minor trail scratches while resisting the UV exposure that destroys cheaper vinyl covers during those long desert runs.
The aluminum construction keeps weight low—about 95 pounds total—so you’re not adding unnecessary payload to your Jeep. Our powder-coat process creates a durable surface that won’t crack in freezing temperatures or blister under summer sun. The panels connect with industrial-strength hinges that we’ve tested through 50,000+ open-close cycles, and the rubber seals compress firmly against your bed rails to keep dust and moisture out even during highway rain or off-road creek crossings.
No-Drill Installation System for Your 2020+ Gladiator
Our clamp-on rail system mounts to your Gladiator’s bed without drilling a single hole. The installation kit includes pre-assembled side rails with adjustable clamps that grip your bed rails from the inside, securing the MX4 firmly while preserving your truck’s resale value.
Most Gladiator owners complete the installation in 20 to 30 minutes with basic hand tools. We include detailed instructions specific to the 2020-2024 Gladiator bed configuration, and the rails feature alignment guides that ensure a perfect flush fit on the first try. The clamps tighten with a standard socket wrench, and you can fine-tune the rail position to account for any bed cap variations.
Security Features & Locking Mechanism
We equipped the MX4 with our dual automatic latch system that locks the panels securely at your Gladiator’s tailgate. When you close the final panel, both latches engage automatically—no fumbling with separate locks or trying to align multiple locking points.
The latches integrate with your factory tailgate lock, so securing your bed cargo is as simple as locking your tailgate with your Jeep’s key. This creates a theft deterrent that keeps casual opportunists away from your gear while you’re parked at the trailhead or stopped for food on a road trip. The latches are serviceable and designed to withstand the vibration and flex that comes with off-road driving.

Common Questions About the BAKFlip MX4 for Jeep Gladiator
Yes, the MX4 is designed to fit all 2020, 2021, 2022, 2023, and 2024 Jeep Gladiator models with the standard 5-foot bed. This includes Sport, Overland, Rubicon, Mojave, and all other trim levels with the factory 60-inch bed length.
The cover uses our universal clamp-on rail system that accommodates minor bed rail variations between trim packages. Whether your Gladiator has factory bed caps, spray-in liner, or drop-in liner, the MX4 installs securely with the included hardware.
You can absolutely install the MX4 yourself in 20 to 30 minutes with basic hand tools. Our clamp-on design requires no drilling, so there's no risk of damaging your Gladiator's bed.
The installation kit includes pre-assembled side rails and detailed instructions specific to the Jeep Gladiator bed configuration. You'll need a socket wrench to tighten the clamps, and we recommend having a second person help position the rails for easier alignment. Most Gladiator owners complete the installation on their first try without any issues.
The MX4 has a load capacity of 400 pounds evenly distributed across the closed panels. This means you can safely place gear, equipment, or even carefully walk on the cover when accessing your roof rack or cleaning your Jeep.
We engineered the aluminum panels and hinge system to handle this weight without flexing or damaging the cover. However, we recommend distributing weight across multiple panels rather than concentrating it in one area, and always ensure your cargo is properly secured before driving.
The MX4 is weather-resistant rather than completely waterproof. Our integrated seal system and drain channels keep your Gladiator bed significantly drier than an open bed or soft tonneau cover, but like all folding tonneau covers, it's not designed to create a watertight seal.
During normal rain and snow, the MX4 provides excellent protection—most cargo stays completely dry. However, during extreme weather like heavy downpours or pressure washing, some moisture may enter through the panel seams. We recommend using waterproof bags or containers for electronics or items that must stay absolutely dry.
Yes, you can drive with the MX4 panels folded in any position—one panel open, two panels open, or all four panels stacked against the cab. The hinges lock securely at each folding position, and the panels won't flap or move during highway driving.
Many Gladiator owners fold panels open when hauling taller cargo that extends above the bed rails, or when they want quick access to the front section of the bed without fully removing the cover. Just ensure any cargo is properly secured and doesn't interfere with the folded panels.
The MX4 is compatible with most spray-in bed liners and drop-in bed liners for the Jeep Gladiator. Our clamp-on rails mount to your bed rails regardless of liner type, and the cover sits flush with the top of your bed rails.
For bed extenders, you can use most styles when the MX4 is folded completely open against the cab. However, when the cover is closed, most bed extenders won't fit since the MX4 panels extend to the tailgate. If you frequently use a bed extender, you'll want to fold the cover open or consider our BAKFlip CS which includes an integrated rack system designed for accessory mounting.
The MX4 features our matte black powder-coat aluminum finish and is our most popular hard folding cover for Gladiator owners seeking excellent protection at a great value. Our BAKFlip G2 offers upgraded hinge durability and enhanced finish coating for owners in extreme climates.
For maximum durability, the BAKFlip F1 uses fiber-reinforced polymer panels with a gloss finish. If you need integrated rack mounting, the BAKFlip CS combines the folding cover with a full cargo management system. All models use the same clamp-on installation system and provide four-panel folding access.
