UnderCover Armor Flex Tri-Fold Tonneau Cover (16-24 Titan XD w/ 6-1/2-Foot Bed)Find parts that fit my vehicle

Good extra storage space

I bought this 2025 Tundra non-hybrid knowing there was some storage under the backseat but this really was a great advantage for more additional room. I love that they swing out where you can easily access them and they lock in place and don't rattle. I also like the fact that they can be easily removed if you need the extra room. The lids do lock and there is a lock to prevent them from someone just taking them. However...that little plastic piece with the tiny lock is pretty flimsy. Sure wish they would have put something a little more substantial in there. Also it would have been nice to beef up the hinges a little more. They say the tool boxes are rated for 40lbs and I wouldn't go beyond that. This may seem like I'm nitpicking and maybe I am, but for the price I think customers deserve those extra couple of upgrades. On another positive note I have ran them through the car wash many times and not a drop off has penentrated, so that is awesome.

Install was easier than expected.

They click well. Hold without wiggle. Swing around 110 degrees (can access with the tonneau cover fully on). Recommendation: install the self-tapping screws last after you get the hinge and clasp all lined up.

Like it’s very convenient doesn’t take a lot of room and you put what you need is a good product

Really nice cover

Wanted a folding, locking cover with a scratch resistant finish that still gave full bed access. Although pricey, this was the ticket. Does it job well. Opens and closes, latches, looks awesome. The textured finish looks good and wont show any nicks or scratches and easy to fix. It did leak where the rails meet the plastic bed caps, but some black silicone eliminated that. Also nice is 2 screw wheels and the whole thing is out in 5 min. Not that you need to cause it open all the way with the props. Side note, i was able to make it work flawless with the Fishbone Chase Rack.

Perfect fit and easy to install

I have a 2024 Tacoma TRD OR 6’ bed. I did a lot of research looking at different designs and brands. The UnderCover Armor Flex stood out as the perfect fit for what I wanted. Extreme Terrain helped me get the order placed at a good price and it arrived in 3 days!! The install was easy and it looks amazing! The only thing I would suggest is during the install on step 5, line up the side rails to the adapter rail at the tailgate end (do not push the rail all the way toward the cab). You will get a much better fit and it lines up a lot better. I absolutely love the way it looks!

Added storage

I like them, they added much needed storage to my truck for storage of receiver and assorted trailer stuff, jumper cables, gloves Easy to install with the templates, easy access under my tonneau cover

Storage

Great storage container and I bought them for both sides. Easy install and lots of room. Doesn’t lose bed space.

Storage

Awesome buy and takes up zero room. Great space inside, holds more than it looks.

My 3rd one!

It is a great product! I have worn and abused 2 of them thoroughly! I will ALWAYS use these storage boxes! They take a beating and keep on working until I just finally ruin one and so easy to replace!

Great Storage Box

Easiest item to install. Four bolts and you're done. Holds quite a bit of stuff. Perfect for your hitch and various tools with quick access.
