    Measure Your Truck Bed for a Tonneau Cover

    Does your truck have a track system?

    The Undercover Flex is constructed of Fiberglass reinforced polymer and aluminum. The aluminum provides structure and rigidity while the fiberglass reinforced polymer protects against scratches and dents. The Flex also utilizes EPDM rubber seals and hinges so it provides maximum security from rain and snow.
    The Undercover Flex installs easily with no drilling thanks to the clamp-on design. You only need basic tools like a socket wrench to complete the installation on most vehicles. One of the best features the Flex offers is the ability for you to gain full bed access without having to remove the cover completely. You simply fold the cover panel by panel to the front of the bed, then attach the prop rods to secure it upright position. The truck can safely be driven with the cover in this position at highway speeds.
    Undercover warrants this cover against any manufacturing defects for a period of 3 years. The cover also is made in the USA so you can rest easy knowing the quality is second to none.

    Bought this for my 14 f150. Installation was simple and fast. So far no leaks and it's winter in central NY. Built well and looks great. Highly recommended this cover. Kind of pricy but worth it.

    This was a perfect fit for my 2013 Toyota Tundra. Easy installation and great looks. Minimal water intrusion but just because I didn't get a good seal on the tape at the front. Will likely replace the tape and fix the issue.

    Great and good looking cover for a reasonable price. Easy to install. Just one small damage in one of the tubes to drain the water. Could have returned it but it does not affect the performance of the cover.

    This is my second Undercover flex. I bought my second one because my new truck had a different size bed. Ever since I bought my first Undercover Flex, I have been very pleased with this product. It is very versatile for all my different needs. Great quality and Realtruck gave me the best price possible plus fast and free shipping.
