When it comes to gymnastics, politics and truck bed cargo control-flexibility is key. And, there's no better way to touch your cargo-covering toes than with the Undercover Flex Tonneau Cover. Undercover's first folding tonneau features a sleek, low-profile design that folds away to reveal your entire truck bed.

Featuring 3 folding panels, the Flex cover folds completely forward and back to deliver full bed access and maximum security. The low-profile design sits flush with your truck's bedrails for a super sleek and slippery style that improves MPG, too. And, thanks to the simple clamp system, the Undercover Flex is easy to install and remove with no drilling required.

Crafted from a fiberglass reinforced polymer with a subtle textured finish, the Flex shoulders up to 400 lbs. And, it'll never crack, warp, fade, rust or corrode. Connected by seamless leak-proof rubber seals and featuring an integrated drain tube, the entire assembly keeps your bed clean, dry and secure. Best yet, Undercover backs your Flex Tonneau Cover with a 3-year warranty.

Had this on a previous truck, and bought it again, would give 5 stars, but I think the ease of getting into it with a coat hanger is a bad design and need to open back part to close tailgate I'll mod it to make it more secure. Other than that I like this cvr

I had a solid undercover tonneau on my 2014 Ram 1500 crew cab. Replaced it with the Flex. Many unrefined and sharp edges on Flex. Got scratched and cut 4 times during installation. I am normally very good at mechanics. Do my own brakes, oil, basic maintenance. Also, there should be a center release for the rear section. Took me about an hour to install. Looks nice. Also, my flip-over bed extender doesn't work because of the rails. Literature should include this information. $300 out the window.

Nice looking and decent fit!

It is nice to be able to hide and lock things without using the cab. Good looking too. HELP FOR YOU: On the rail version, you need to remove the tiedowns to fit. The drip tubes fit in the holes, but can't turn down in cavity, so trim them short, loose foam strip goes on top of rail cap. Cover gaskets need heat to mold to shape of rail cap.

I love this bed cover and how it allows for different positioning depending on the size of the cargo I am hauling. Everything fit perfectly and the installation instructions were easy enough to follow. Took me about 30-40 minutes to install by myself.
