BAKFlip MX4 Hard Folding Tonneau Cover Suitable for RAM 1500 DT 5'7 Bed with RAMBox by BAK Industries
The BAKFlip MX4 is a hard folding tonneau cover designed to suit RAM 1500 DT models with a 5'7 bed and RAMBox. It gives the tub a clean, low-profile look while adding practical protection for tools, camping gear, recovery equipment, and everyday cargo.
Built with aluminium panels and a full matte black finish across the top of the cover, the MX4 is made for drivers who want a strong, tidy-looking cover without a bulky appearance. The matte-finished cab corner caps, clamps, elevator bolts, rail end caps, and upgraded bumpers help give the cover a more complete, factory-style finish.
The folding design gives you quick access to the tub when you need it. The cover can be driven in the 2/3 open position or fully open position, giving you more flexibility when carrying taller or awkward gear. Upgraded prop rod clips help hold the cover securely when opened.
The MX4 also includes EPDM seals and upgraded seal end caps to help improve water resistance. Like most tonneau covers, it is designed to reduce water entry rather than make the tub fully waterproof, so sensitive gear should still be packed accordingly.
Installation is designed to be straightforward, with no drilling required for the cover itself. Drain tubes are included, although drilling may be required on some vehicles depending on the tub setup.
Why Upgrade?
The MX4 is a practical upgrade for RAM 1500 DT owners who want stronger tub coverage, cleaner styling, and better everyday usability than a basic soft cover. Its hard aluminium panel construction gives added protection, while the folding design keeps the tub accessible when you need to load larger items.
It is built for regular use, with upgrades to the prop rod clips, rails, elevator bolts, and bumpers to improve function and finish. For work, touring, or general weekend use, it gives the RAM tub a more secure and polished setup without overcomplicating access.

Frequently Asked Questions
What exact configuration is this cover designed for?
This cover (SKU UF-BAK-00030) is designed specifically for the RAM 1500 DT with a 5'7" bed and RAMBox. If your RAM 1500 DT has the same 5'7" bed but without RAMBox, the correct cover is UF-BAK-00002. The RAMBox variant uses a different rail and clamp configuration to match the bed geometry of RAMBox-equipped trucks, so the two versions are not interchangeable.
Does the tonneau cover block access to the RAMBox storage compartments?
The MX4 for RAMBox models is designed to mount on the bed rail profile specific to RAMBox-equipped trucks. The RAMBox compartments sit in the bed sides below the rail level and are not blocked by the cover being open or closed. The RAMBox lids open upward and outward, and with the tonneau cover in place there may be a slight reduction in how far the lids can open. If you use the RAMBox compartments frequently, it is worth confirming clearance before ordering.
What is included in the kit?
The kit includes the folding aluminium tonneau cover, side rails, mounting clamps, hardware, drain tubes, and an installation guide. Everything needed for a standard installation is included, though some vehicles may require minor drilling to route the drain tubes depending on the tub configuration.
How does the folding mechanism work day to day?
The cover folds in sections from the rear toward the cab. You release the latch at the tailgate end and fold the panels forward, either stopping at the 2/3 position for partial tub access or folding all panels fully upright for near full-tub access. BAK's auto-latching side rails lock the cover automatically as you close it, so there is no separate step needed along the bed length. Upgraded prop rod clips are designed to hold the cover securely when fully open.
What weight can the cover support when closed?
The MX4 is rated to support up to 400 lb (approximately 180 kg) of evenly distributed weight across the closed cover panels. This suits loading flat gear or supplies across the top, but weight should be spread as evenly as possible across all panels rather than concentrated on a single section or hinge point.
How does this RAMBox version differ from the standard version for the same tub size?
The RAMBox version (UF-BAK-00030) uses a rail and clamp configuration designed to seat correctly on the modified bed rail geometry of a RAMBox-equipped tub. The without-RAMBox version (UF-BAK-00002) fits a standard flat bed rail profile. Both versions share the same panel design, features, and finish, but they are not interchangeable. Using the wrong version for your tub configuration will result in an incorrect fit.
Can I drive with the tub partially or fully open?
Yes. The MX4 supports driving in a 2/3 open position, where the rear section of the tub is exposed while the front remains covered, or with all panels folded fully toward the cab for near full-tub access. This is useful for transporting taller or longer items that would not fit under a closed cover. Upgraded prop rod clips are designed to hold the cover firmly in the fully open position while driving.
How does the MX4 compare to the Revolver X4s rolling cover for the RAM 1500 DT with RAMBox?
The Revolver X4s is available for the RAM 1500 DT Crew Cab with RAMBox and uses a rolling mechanism that coils the cover toward the cab rather than folding it upward. Rolling covers tend to provide a cleaner open-bed profile at the rear and slightly better rear visibility when open. The MX4 can be driven in a partially-open position for taller gear, which the X4s does not support in the same way. If you want to mount racks or cargo systems above the tub, the Revolver X4TS with T-slot rails is the option to consider, as neither the MX4 nor the X4s support over-bed rack systems.
