Whether you’re loading your truck up with sand, cement, or concrete, or packing up for a weekend camping trip, your cargo needs to be protected, and your truck deserves to look good. If you want to add all the convenience of a locking trunk to the style and function of your pickup, equip your rig with the BakFlip MX4 Aluminum Tonneau Cover.

Not only do the enhanced heavy-duty aluminum panels look great in their flat matte finish – they also provide incredible resistance to scratches and UV rays. In addition, the premium density foam core stands up strong to heavy use and abuse. The newly upgraded rear seal is universal, and allows you to close your cover while the tailgate is in the open or closed position - no need to worry about damaging your cover when you close the cover in a hurry.

Your BakFlip MX4 Aluminum Tonneau Cover is rated to hold up to 400 lbs of evenly distributed weight right on top. The latch housing is injection molded, for supreme durability that will last for the long haul. This cover is made in the USA and backed by a 3-Year Warranty.

Optional Upgrade: Choose the Standard BakFlip MX4 model, or maximize your truck bed's functionality by adding the optional BakBox Folding Toolbox. This truck toolbox is strong, lightweight, easy to handle, and works seamlessly with the BakFlip MX4. (BakBox not available for all vehicles.)

Was fast and easy to install. Works very well. This cover is on my wife’s truck and she has no trouble using it. And the best thing about it is that you don’t have to use a key to unlock it.

It took a bit longer it was my first time installing one. Clean up screw holes before you start. Aluminum fillings left in the holes. Check hardware before you start. Had 1 screw and nut won't tighten all the way. I do love my cover. Looks great fits well.
