BAKFlip MX4 Hard Folding Tonneau Cover for 2010-2024 Ram 1500 / 1500 Classic without RamBox (5'7" Bed)

The 5'7" short bed is the popular crew-cab setup on the 2009-2018 Ram 1500 and the 2019-2024 1500 Classic, and this BAKFlip MX4 locks it down without RamBox. It clamps to your factory bed rails with no drilling and folds flush to the cab in seconds, so you keep easy bed access while your cargo stays secure and weather-protected. Low, matte, and clean, it looks factory over the short bed.

What's Included:

• BAKFlip MX4 hard folding tonneau cover, pre-assembled
• Two clamp-on mounting rails
• Integrated tailgate seal
• Drain tubes
• Clamp and hardware kit
• BAKFlip hard-folding install guide

Features

The Original Hard-Folding Cover, Now Gen 3
The BAKFlip MX4 defined the hard-folding category and the Gen 3 keeps it at the top. Patented auto-latching, premium aluminum panels, and a low, flush profile give you a cover that looks factory and works like it was engineered for your truck, because it was.

Automatic Latching Security, Standard
The patented auto-latch system locks each panel down the instant you fold the cover closed, with no separate key or lever step. With the tailgate shut and locked, your gear sits under a cover that cannot be opened from outside.

Sealed Edge to Edge Against the Weather
Revised EPDM perimeter seals and tight-fit clamps close the gap between the cover and your bed rails, and a longer dual-action tailgate seal protects the back edge. Integrated drain tubes carry water off the cover and out through the bed. Like any folding cover it is water-resistant rather than submersible, but it keeps rain, dust, and spray off your cargo.

Built Stronger, Built to Last
Heavy-duty aluminum skins over a high-density polymer core make the Gen 3 panels about 22 percent stronger than the original MX4, with a textured matte finish that resists UV and scratches. This is multi-layer construction that will not bow or flex the way single-layer covers do under pressure.

100 Percent Bed Access, Brake Light Clear
Fold the panels flush against the cab, secure them, and drive with the bed fully open for tall or oversized loads, no removing the cover. The MX4 is the only hard fold that leaves your third brake light visible in every position.

One-Person Install in Under 30 Minutes
The all-new click-in design clamps to your factory bed rails with the included hardware, so most trucks install in under 30 minutes with basic hand tools, no drilling and no second person. Assembled in the USA and backed by a 5-year warranty with US-based product support.
