The Undercover Armor Flex is a hard folding tonneau cover constructed of aircraft grade aluminum panels. A highly durable, matte black Line-X finish offers superior protection against scratches, while offering UV resistance. The Armor Flex uses EPDM rubber seals and hinges so it provides maximum resistance from rain and debris. The tonneau rails also aid in this by channeling excess water through the provided drain tubes, helping to keep your cargo safe from the elements.

The Undercover Armor Flex has a simple installation with no drilling due to the clamp-on design. All that is needed are basic tools like a socket wrench to complete the installation on most vehicles. A great feature of the Armor Flex is the ability to allow full bed access without having to remove the cover. Simply fold the cover, panel by panel, to the front of the bed, then secure the prop rods that hold it in the upright position. The truck can safely be driven with the cover in this position at highway speeds.

Another great feature of the Armor Flex tonneau cover is the dual action tailgate seal. This seal lets you close the tailgate without needing to open the cover, while also letting you close the cover without lowering the tailgate. The automatic slam latches open from either side of the bed, and automatically lock the cover as it closes. These features add a versatile action to the cover, making it simple to operate. Undercover protects this cover against any manufacturing defects for a period of 5 years.

How to Install UnderCover Armor Flex Tonneau Cover on a 2014 Ram 1500 5.5ft bed


UnderCover, Inc. warrants the structure of your Armor Flex Cover to be structurally free from defects in material and workmanship for (5) five years from the retail date of purchase. The hinges, seals, and hardware are warranted to be free from defects in material and workmanship for (5) five years from the retail date of purchase. This warranty applies only to the original purchaser and is nontransferable. Your original sales receipt will serve as proof of purchase for this warranty. Before credit can be issued on a warranty claim, proof of defect may be required. This can be determined at the time of the claim.

Not covered under this warranty is failure due to neglect, improper installation including any modifications to installation hardware, alterations, addition of equipment, abuse, accident, weather-related damage, exposure to chemicals that are not labeled "safe for rubber" and normal wear from lack of maintenance.

Always read the ingredients of any product you are using to clean your Flex Cover. Make sure that you use only products that are safe for use with rubber. Many chemicals contain material that will permanently discolor or damage your Flex Cover hinges and seals. This is not considered a manufacturer defect.

Incidental or consequential damage or loss of contents due to use, neglect, lack of maintenance, misuse or abuse of the Flex Cover is the sole responsibility of the truck owner and operator. Paint damage to your truck is not covered under this warranty. When operating your truck always keep the Flex Cover in either the fully closed and latched position, or one of the two approved open positions. The first approved open position would be the first, second, and third panel stacked onto the forth panel and the buckles must be secured together. The second approved open position would be all four panels standing up vertically behind the cab. In this position both prop rods must be attached and the buckles secured. Do not operate the truck at excessive speeds with the Flex Cover in either open position.

In the event that your Flex Cover is found to be defective under the terms of this warranty, it is at the discretion of UnderCover, Inc. to repair or replace the defective part. All repairs must be made under the direction of UnderCover Inc. UnderCover Inc. is not responsible for any transportation costs associated with the warranted claim.

The panels of your Flex Cover require only periodic cleaning with mild car wash soap. Avoid use of all abrasive type cleaners as they may dull the finish. Some chemicals and fluids such as insect repellents, oils, solvents, and lubricants could potentially damage the rubber hinges and seals and void the warranty.
