BAKFlip MX4 Tonneau Cover for RAM 1500
Our BAKFlip MX4 for RAM 1500 combines heavy-duty aluminum panels with a low-profile design that sits flush with your truck bed rails. This hard folding tonneau cover opens in multiple positions—from partial access to completely folded against the cab—giving you flexibility whether you’re hauling tall cargo or securing everyday gear.
The matte black finish resists UV damage and integrates seamlessly with your RAM’s styling. We engineered this cover with automatic latching for quick operation and dual-action tailgate seals that lock out moisture and dust. Installation requires no drilling and uses our clamp-on rail system that works with factory stake pocket holes.
- Aerospace-grade aluminum panels with reinforced hinges resist dents and corrosion
- Fits RAM 1500 models 2009-2018 & 2019+ (classic body style) with 5’7″, 6’4″, and 8′ bed lengths
- Folding design allows tailgate operation with cover closed or open
- Automatic latch system engages when panels fold down—no separate locks to turn
- Dual-action tailgate seal blocks water entry at all four corners
Panel Construction & Weather Resistance
We build every BAKFlip MX4 RAM 1500 panel from .040-inch aluminum alloy that withstands impact without permanent creasing. The extruded hinge system uses stainless steel pins that won’t freeze or bind in cold weather, and each hinge point includes an integrated rubber seal to prevent water migration between panels.
The powder-coat finish goes through a seven-stage wash and cure process before application, creating a surface that resists scratches from cargo sliding and won’t fade under direct sunlight. Our matte texture matches the bed liner texture on most RAM 1500 trucks for a factory-integrated appearance.
Bed Access & Folding Positions
The four-panel design of the BAKFlip MX4 for RAM 1500 divides into sections that fold forward in any combination you need. Unlock the rear panel for access to the last quarter of your bed while keeping the front three panels secured. Flip all four panels against the cab for full bed access when loading furniture or plywood sheets.
Each panel locks independently using our automatic latch mechanism—simply press down until you hear the click, and the internal cam system engages. No separate key locks or twist knobs required for everyday operation. The cover remains stable at any folding angle thanks to tension adjusters built into each hinge.
Installation & Bed Rail Compatibility
Our clamp-on rail system mounts to your RAM 1500 bed without drilling holes or applying adhesive. The side rails slide into position along the bed rail caps and secure using adjustable clamps that fit into existing stake pocket locations. Rubber pads on each clamp protect your truck’s finish and prevent the rails from shifting during heavy loads.
The installation process takes 30–45 minutes with a socket wrench and an assistant to help position the rails. We include vehicle-specific installation brackets calibrated for RAM 1500 bed dimensions, so you won’t need to measure or trim any components. The rails sit low enough to maintain clearance if you later add a crossbar accessory system or bed-mounted tie-downs.

Common Questions About the BAKFlip MX4 for RAM 1500
Yes, the MX4 is compatible with most factory spray-in bed liners on 2022 RAM 1500 trucks. The clamp-on rail system accounts for bed liner thickness up to 0.5 inches. If you have an aftermarket drop-in liner with raised side rails, measure the rail height before ordering—we can provide spacer kits if needed for proper fitment.
You can open your RAM 1500 tailgate with the BAKFlip MX4 fully latched, giving you access to items near the tailgate without unlatching any panels. For deeper bed access, simply unlatch and fold back one or more panels as needed. The cover is designed to operate with the tailgate in any position.
The aluminum construction and stainless steel hinges resist corrosion from road salt, and the EPDM rubber seals remain flexible in sub-zero temperatures. Snow and ice slide off the matte finish easily. The automatic latches continue to function in freezing conditions—we recommend applying silicone lubricant to the hinge pins before winter for optimal operation.
Installation requires a socket wrench set, a measuring tape, and approximately 30–45 minutes of time. No drilling or permanent modifications are needed. We include all mounting hardware and clamps calibrated for RAM 1500 bed dimensions. Having a second person to help position the side rails makes alignment easier but isn’t mandatory.
Yes, you can drive at highway speeds with the BAKFlip MX4 fully folded and secured against the cab using the included retention strap. The strap clips to anchor points on the side rails and keeps the stacked panels from unfolding during travel. This configuration is ideal when you’re hauling tall cargo that won’t fit under the closed cover.
The standard BAKFlip MX4 rails are designed for RAM 1500 models without RamBox. If your truck has the RamBox side storage bins, you’ll need our RamBox-specific rail kit, which accommodates the wider bed configuration. Contact us before ordering to confirm which version matches your truck’s bed setup.
The BAKFlip MX4 for RAM 1500 supports up to 400 pounds of evenly distributed weight when all panels are latched. This allows you to stack camping gear, coolers, or bags of materials on top during transport. Avoid concentrated loads in a single spot—distribute weight across multiple panels and place heavy items over the crossbar supports for best results.
