BAKFlip MX4 Dodge Ram 1500 Tonneau Bed Cover

Sleek, secure, and durable–what else could you want? The bakflip-MX4 tonneau cover is a top-of-the-line hard-folding cover engineered for maximum aesthetics, weather resistance, and security.

The bakflip-MX4 is constructed entirely from alloy materials, including heavy-duty aluminum top panels and side rails. Unlike comparable soft-folding tonneau covers, you can't simply slice through the MX4 with a pocket knife. No matter the cargo in the bed, you can rest assured that your gear's protected by a premium bed cover from BAK industries.

Full Bed Access

When you need to haul large items, just fold the cover toward your cab and secure it in place with the supplied prop rods. The prop rods rest in an improved rail clip when not in use and upgraded cab bumpers prevent the cover from scuffing your paint.

Upgraded Side Rails

Channeled rails hold the cover in place while shut. These rails feature rubberized endcaps, which prevent any raw aluminum from being exposed.

Universel Tailgate Functionality

Triple fin seals allow the tailgate to operate whether the cover is open or closed. The cover can be closed with the tailgate up too.

Matte Black Finish

The all new matte black finish offers superior scratch resistance and UV protection.

No Drill Clamp

The MX4 can be installed in less than an hour without drilling into the truck bed.

Easy Operation

Each panel automatically latches to the cover's mounting rails as the cover closes. Latches deactivate with a simple pull of the cable.

California Residents

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov

Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.

The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov
