Undercover Flex FAQ

  • What is the warranty for my Ultra Flex Cover?
    Your Flex Cover has a five year warranty.

  • What tools will I need to install the Ultra Flex Cover?
    A 9/16 wrench is the only tool required to install the Ultra Flex Cover. Ultra Flex Covers require no drilling to attach the cover to the bed. Some applications may require drilling for the drain tubes.

  • Is the cover waterproof? Will I have leaks?
    The main feature of the Ultra Flex Cover is its quick access to the truck bed. The UltraFlex Cover is water resistant but not waterproof. There are built-in drains to channel 99% of the water away from the bed. For a watertight bed cover we offer the UnderCover hard tonneau that may be a better alternative.

  • Will the Ultra Flex Cover work with my drop-in bed liner?
    Yes, your Ultra Flex Cover works perfectly with most under the rail drop-in bed liners (some minor trimming may be required).

  • I have a spray-in liner and a bed extender, will the Ultra Flex Cover work for me?
    Yes, the Ultra Flex Cover works with bed extenders and factory cargo management systems. Any additional hardware needed for the Ultra Flex Cover to mount with factory cargo management systems is included for the particular application.
