    • Great quality and looks!
Color: Matte Black Size: 5' 10" Bed Configuration: Flush Fit
Got the Ultra Flex cover for our 2019 GMC AT4 Sierra about a month ago. So far we are happy with it, we previously had a soft tri- fold tonneau cover on our previous truck and it was ok but started cracking on the folds so decided this time to upgrade to a hard version. We like the quality and love the looks of this cover. it’s easy to install, only needed help placing it on the truck because it’s a little more weight than a guy in his seventies with a bad back wanted to lift but everything else went well and was not a problem . It costs more than the soft version but If you plan on keeping your truck for awhile it’s worth the money. I’m not a expert but would recommend this product to anyone looking for a hard tri- fold cover ... show more

    • Love the Line-X feature!
Color: Premium Line-X Coating Size: 5' 10" Bed Configuration: Flush Fit
This cover delivers once again. Sits super low at the height of the bed rails. I owned the Undercover Ultra flex for my 2014 Silverado and was quite satisfied with it’s initial quality but overtime there was a small amount of fading. This is not as severe as the undercover flex that is fiberglass but still worth noting. I needed a bed cover for my 2019 Sierra and stumbled on the this cover. The ArmorFlex seems like it will fix thus issue with use of Line-X. Even though Line-X will fade a bit you can use conditioner to restore the shine. Also this version will be far leas likely to scratch. ... show more

    • Not perfect for the 2024 Sierra 1500 Denali Rear View Camera when Folded Up
Color: Matte Black Size: 5' 10" Bed Configuration: Flush Fit
I previously owned the Armour Ultra Flex cover, but opted for the Ultra Flex cover. I like the smooth finish, carpeted under panels, and the matte black finish. I am very pleased with the aesthetics of the cover. A couple of issues, I do not care for are: When folded and braced in upright position the cover blocks the rearview mirror / bed camera so driver cannot view bed or utilize the rearview mirror - may not have purchased if I knew this; the rails are not as rigid as I would prefer. Making it a point to clamp the ends of the track as close as possible to the tailgate is essential, as well as torquing the clamps to 10ft.lbs as called for in the instructions. If not torqued, or clamps are not placed correctly, the latches will not catch when closing due to rails flexing. In the end, I chose to keep the cover and believe it will serve me well. Will always wish they would have worked harder to allow driver to view rearview camera so they can drive safer and view items in bed. ... show more

    • Love My New Truck Bed Cover
Color: Premium Line-X Coating Size: 5' 10" Bed Configuration: Flush Fit
I have had several truck bed covers in the past but this is by far the best I have had. It cost more than I have spent before but well worth it. It is durable, low profile and looks amazing! I also love how you can open it with one hand. I would definitely recommend this to any truck owners.

    • Keep scrolling past this topper!
Color: Matte Black Size: 5' 10" Bed Configuration: Flush Fit
This cover isn’t what you expect it to be seeing that it’s one of the most expensive choices. Install was easy but leaks everywhere from day one. It’s sad that I have to put this disclaimer but if you need a dry truck bed cover look elsewhere because that’s the point of having one in the first place! ... show more

    • 2019 GMC
Color: Premium Line-X Coating Size: 5' 10" Bed Configuration: Flush Fit
I purchased this primarily due to the Line-X coating on the top. The biggest complaint I saw on all these Tri fold units was they scratched easily. The other was that they weren't packed properly for shipping and had to be exchanged (hauling one of these back to the UPS store is a drag I hear). My unit showed up in great shape. Had it installed on my truck before the sun set on the same day. ... show more

SOLID IN QUALITY, DURABLE - LOVE THE SPACE WITH THE FOLDS IN BED OF TRUCK. THE BOX CAME DAMAGED WITH TAPE ALL OVER THE BOX COVERING HOLES. I HAD TO BUY EXTRA PARTS AT A HARDWARE STORE TO INSTALL. I WOULD HAVE SENT IT BACK, BUT WAS OUT OF STATE AND RAN OUT OF TIME FOR MEET THE DEADLINE TO RETURN. SEVERAL KEY PARTS WERE MISSING DUE TO THE OPENINGS IN THE BOX. OTHER THAN THAT IT LOOKS GREAT.

Love the look, ease of use is great, durable and easy to install. The product was easy to install if you read the instructions and have some mechanical abilities. It was pretty easy to figure out. The cover looks great and worked as it was described. I love the look and the carpeted underside for ease of using it as a bench when opened. ... show more
