MX4 RAM 1500 specifications
Premium Aluminum Panel Construction
We build the BAKFlip MX4 with heavy-duty aluminum panels that deliver superior strength without adding unnecessary weight to your RAM 1500. Each panel features a textured matte black powder-coat finish that resists scratches, UV damage, and corrosion — essential for withstanding years of highway driving and job site conditions.
Engineered for Durability
The aluminum construction provides a rigid platform capable of supporting 100 lbs per panel when properly closed and latched. This means you can confidently load gear on top of the cover or access your bed from the sides of your truck. Our proprietary hinge design uses stainless steel components that won’t rust or bind, ensuring smooth panel operation through countless open-close cycles.
Installation & RAM 1500 Compatibility
We designed the BAKFlip MX4 with our signature clamp-on installation system that requires zero drilling into your RAM 1500. The entire installation process takes 30-45 minutes with basic hand tools, and we include everything you need in the box.
Our MX4 fits RAM 1500 models from 2009 through 2025 with the standard 6’4″ bed. The cover works seamlessly with factory bed rail caps and integrates with most spray-in bed liners. If your truck has a RAM Box cargo management system, please verify compatibility with our fitment guide before ordering.
Folding Versatility & Cargo Access
The four-panel folding design gives you unprecedented flexibility in how you use your RAM 1500 bed. When closed, the MX4 sits just one inch above your bed rails for a low-profile look that improves aerodynamics and fuel efficiency. Our testing shows an average 12% improvement in highway fuel economy compared to driving with an open bed.
You can fold the panels in multiple configurations depending on your cargo needs. Fold one panel for quick access to the front of the bed. Fold two panels to haul medium-sized items like coolers or toolboxes. For maximum versatility, fold all four panels completely against the cab — this gives you 100% bed access for transporting lumber, ladders, or tall equipment.

Common Questions About the BAKFlip MX4 for RAM 1500
Yes, the MX4 is compatible with most spray-in bed liners including LINE-X, Rhino Linings, and Speedliner. Our clamp system adjusts to accommodate the added thickness of spray-in liners. If you have a drop-in plastic bed liner, you'll need to remove it before installation as the MX4 is designed to mount directly to the bed rails.
The cover works with RAM 1500 factory bed rail caps in place. Simply position the clamps over the existing rails and tighten according to our instructions.
Each aluminum panel supports 100 lbs when the cover is fully closed and both latches are engaged. This distributed weight capacity means you can safely load light equipment, cargo bags, or camping gear on top of the closed cover.
Important: The panels are designed for distributed loads only — do not stand or kneel on the cover. The 100 lb per panel rating applies when weight is evenly distributed across the panel surface.
The BAKFlip MX4 is designed for DIY installation with no drilling required. Most RAM 1500 owners complete the installation in 30-45 minutes using basic hand tools. We include detailed step-by-step instructions and all necessary mounting hardware in every kit.
The panels come pre-assembled — you simply position the cover on your bed rails, attach the clamps, and adjust the tension. If you prefer professional installation, many truck accessory shops and dealerships offer installation services. We also provide video installation guides on our website for visual step-by-step assistance.
No, the low-profile design of the MX4 sits just one inch above your RAM 1500 bed rails and does not obstruct your backup camera view or interfere with tailgate operation. You can open and close your tailgate normally with the cover installed.
The cover's slam-latch system automatically engages when you close the tailgate, securing the cover without additional steps. Your truck's factory tailgate lock continues to function normally, and you can optionally key the MX4 latches to match your ignition key for convenient single-key access.
The MX4 features premium EPDM rubber seals at every panel junction that create an excellent weather barrier. While no tonneau cover is 100% waterproof (they're designed with drainage to prevent moisture buildup), the MX4 keeps your cargo dry in normal rain and snow conditions.
Integrated drain tubes channel any moisture that enters through the seals away from your truck bed. We've tested the MX4 in extreme weather from heavy rainstorms to snow loads, and it consistently protects cargo from the elements. For sensitive electronics or items that require absolute protection, we recommend using additional waterproof storage containers inside the bed.
The MX4 features heavy-duty aluminum panel construction with a matte black powder-coat finish — it's our most popular hard folding cover for RAM 1500 owners who want proven durability at a competitive price.
Our G2 model adds integrated LED lighting and a gloss finish. The F1 uses fiber-reinforced polymer panels for lighter weight and enhanced corrosion resistance. All BAKFlip models share the same four-panel folding design and clamp-on installation, but differ in materials and features. Visit our comparison page to see detailed specifications for each model and find the best fit for your needs and budget.
The BAKFlip MX4 works with our BAKBox toolbox system and certain bed-mounted bike racks that attach to the bed rails. However, it is not compatible with over-the-bed rack systems that require the cover to remain closed.
If your RAM 1500 has the factory RAM Box cargo management system, you'll need to verify specific compatibility as the boxes may interfere with cover operation. For fifth-wheel or gooseneck hitch installations, the MX4 can accommodate most models — simply fold the panels open when you need access to your hitch. Contact our fitment specialists with your specific accessory setup and we'll confirm compatibility before you order.
