If you’re in the market for sleek, stylish bed protection for your pickup, consider the low-profile, color-matched aesthetic of a Fusion Tonneau Cover from UnderCover®. This tonneau cover offers a classic tri-fold design, exceptional security, and professionally paint-matched top panels that blend seamlessly with the body of your pickup.
This tonneau cover features a rugged aluminum panel construction for maximum strength and theft resistance. Unlike theft-prone soft covers, the UnderCover Fusion resists cuts and slashes, keeping the valuables in your truck’s bed safe and secure. However, this cover doesn’t only resist theft but also extreme weather conditions. Integrated EPDM rubber hinges and perimeter seals prevent moisture intrusion, protecting your cargo against heavy rain, dirt, dust, and other contaminants.
Aesthetically, the UnderCover Fusion is tough to beat. Unlike most competitors, which feature a textured black finish that blends into the bed, the UnderCover Fusion features painted top panels that are professionally color-matched to your pickup’s factory paint code, ensuring a flawless match to your pickup’s body. UnderCover backs this finish with a limited lifetime warranty.
Operating the UnderCover Fusion Tonneau Cover is simple and intuitive. The classic tri-fold design features three panels and three sets of hinges, which allow you to fold the cover onto itself toward the bulkhead for cargo access. Whereas most tri-fold tonneau covers only offer ⅔ bed access, the UnderCover Fusion features integrated prop rods that support the cover flush against the rear window for complete cargo access. Installation is also a breeze with UnderCover’s clamp-on L-Rail system.
Closing the cover is just as easy—simply fold it back toward the tailgate as the cover’s automatic slam latches engage with the redesigned L-Rails. The cover’s dual-action tailgate seal allows you to operate the tailgate whether the tonneau cover is opened or closed.
UnderCover is a RealTruck brand. When you order this tonneau cover or any other UnderCover product from us, you’re dealing directly with the manufacturer. We back each UnderCover Fusion Tonneau Cover with a 5-year warranty against manufacturing and material defects.

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!

2020 TRD Pro - SecondTundra
More storage than appears!!
The UnderCover Swing Case Storage System for the Passenger Side of my 2020 Tundra is great. It was very easy and quick to install. The product was light weight, yet appears durable. It fits under the lip of the bed, snug on the wheel well, not taking any bed space. We were so pleased with the one we installed on the drivers side that we added the passenger. We were also pleased that it held more than we expected. Works very smoothly, even with a rhino liner installed first.

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.

2023 Rubicon - DucksGuts
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.

2024 TRD Off-Road - Joejoedarte
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!
