Introducing the UnderCover Armor Flex Tonneau Cover: a premium, hard tri-folding bed cover offering exceptional strength, protection, and sleek styling.

This premium bed cover utilizes a rigid aluminum panel construction for superior strength and theft protection compared to similar soft folding covers. This durable construction is far less susceptible to impacts, abrasions, and sharp blades, keeping your valuables in the bed safe and protected. This cover is so sturdy that UnderCover rates it to withstand up to 400 pounds of cargo evenly distributed on top!

Aesthetically, the UnderCover Armor Flex Tonneau Cover is sleek and stylish. This cover features a low-profile design that sits nearly flush with the bed rails, essentially disappearing into the bed when closed. The outer panels feature a classic, textured black finish, guarding the aluminum and providing a finished appearance that perfectly complements your pickup's existing texture black trim.

Weather resistance is another key feature of a premium tonneau cover, and the UnderCover Armor Flex fares well in this category, too! Using a combination of durable EPDM rubber seals and integrated drain tubes, this tonneau cover keeps excessive moisture where it belongs: outside of the bed! The rear tailgate seal features a convenient dual-function design, allowing you to open and close the tailgate without unlatching the cover; additionally, you can close the cover no matter the orientation of the tailgate.

Operating the cover is quick and easy; simply drop the tailgate and pull the latch release cables at either side of the bed. Then, fold the cover toward the bulkhead, releasing the additional latches as you go, until the cover protects only 1/3 of the bed. You can either secure the cover in this position or flip the cover one additional time against the tailgate for full bed access, using the integrated prop rods to secure the tonneau cover upright.

UnderCover backs the Armor Flex Tonneau Cover with the insurance of a 5-year warranty. If any issues arise during the warranty period, UnderCover has your back!

How to Install UnderCover Armor Flex Tonneau Cover


UnderCover, Inc. warrants the structure of your 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.
