What is the difference between UnderCover Armor Flex and Ultra Flex?
Material Used
Edge: Both
When it comes to hard folding tonneau covers, aluminum is the number one option among manufacturers. This UnderCover ArmorFlex cover is also made of a super-strong matte-finished aluminum panel.
The panel has LINE-X automotive grade coating to protect the cover from scuffs and dents in hard weather.
Conversely, the UnderCover Ultra Flex is constructed with industrial-grade aluminum panels. The panel is lightweight, durable, and has impact resistance ability.
It also comes with a powder-coated matte finish instead of the LINE-X coating and has carpeted panels. Thus, the cover offers a cool and stylish appearance.
Durability and resistance
Edge: UnderCover ArmorFlex
Ultra Flex is UV-protected and has UV resistance. Thus, the tonneau cover can withstand the damaging effects of UV rays and keep its color for a long time.
Unlike other tonneau covers, the aluminum panels of this bed cover are corrosion-resistant. But, the cover isn’t completely scratch resistant, and you may see a few scratches on it after a while. But those dents and scratches won’t damage the look.
Conversely, its distortion-resistant property will ensure longer durability. Armor flex offers advanced protection from scratches, dents, and scuffs. The heavy-duty aluminum panel and Line-X automotive coating help the tonneau endure in extreme environments.

Strength and weight capacity
Edge: UnderCover ArmorFlex
Both the undercover tonneau covers are stronger and hold heavier weights thanks to their aluminum panels. So the tonneau covers are impact-resistant and can withstand thrashing without getting damaged.
The UnderCover Flex and the Armor Flex can both support 300 and 400 pounds of evenly distributed weight. So you can carry anything on the top of these tonneau covers.
Profile
Edge: UnderCover Ultra Flex
Both the tonneau cover and the bed offer a sleek and aerodynamic appearance to the truck with their low-profile designs. Low profiles are beneficial as they hardly sacrifice the factory look while improving gas mileage and reducing wind drag.
Between them, Ultra-Flex comes with an ultra-low profile and lies flusher. It also remains seamless with the truck bed rails. So Ultra Flex is preferable for an extremely low-profile design.

Water resistance
Edge: Both
Honestly, no tonneau cover is 100% waterproof. But these UnderCover tonneau covers are highly water-resistant.
The Ultra Flex has rubber seals all around to prevent water and other road elements from entering the bed. Its tailgate also has a seal to ensure better protection against water.
Both tonneau covers have rail mounting systems to channel water into the drainage tubes to carry it out of the truck. Thus, the cover remains dry and you may hardly notice a few drops of rainwater during heavy rain.
Even though the cover remains watertight during a high-pressure car wash, you won’t notice a single drop of water in the bed.

Security
Edge: Both
You can lock the UnderCover Ultra Flex with the tailgate, and it doesn’t have separate locks. Instead, the tonneau cover has deadbolt locking rails, and these interlock with each other.
This way, the Ultra Flex cover offers the most security and protects the stuff from theft. It also relieves the stress of a rusted lock since the operator doesn’t have to carry different keys for the cover and tailgate.
Conversely, the automatic latching system of the armor flex locks every panel in place securely. The dual-action tailgate seal of the cover allows the user to close the tailgate without lifting the cover. So if anyone tries to open the bed cover without ripping it, he has to open the tailgate first.
