The UnderCover Ultra Flex Tonneau Cover is one of the best hard tri-fold truck bed covers. Tonneau covers cover the top of rear truck beds. People may want a cover for their truck bed for many reasons. The tonneau cover can secure items in the truck bed so that they don’t fall out while driving, or so that they can be safe while the truck is parked and unattended.
The tonneau cover can also help improve the weather durability or aerodynamics of the truck by creating a smooth, water-resistant surface over the top of the truck bed. The improved aerodynamics may improve the gas mileage of the truck. Because the dimensions of truck beds vary between makes and models, it is important to find a tonneau cover that matches the dimensions of the vehicle.
This allows the tonneau cover to attach securely to the sides of the truck bed and operate properly. A properly fitting cover should lock in place, preventing tampering or theft, and should seal off the truck bed, making the area watertight. The cover should not rattle or shift while driving.
Overall Design and Construction
The UnderCover Ultra Flex Tonneau Cover has few sizes. It is designed for the truck and has different options for date ranges. The cover comes in black with three durable coating options: Gloss Finish, Premium X-line Coating, and Premium Matte Finish. The cover weighs 80 pounds.
The UnderCover Ultra Flex Tonneau Cover is made to cover and lie flat over the top of the truck bed. The UnderCover Ultra Flex Tonneau Cover can be configured to be fully covered and locked over the truck bed, be partially open, or be fully open. When fully open, the cover does not just rest against the vehicle. But is upright and propped into place with two metal prop rods that brace against the side of the truck bed.
These prop rods are clipped against the sides of the truck bed when not in use. These metal prop rods are easy to install or remove, but may feel tight during the first few uses. The prop rods secure the cover so that it doesn’t shift or rattle while driving.
The cover is made of three panels of aluminum that lock onto the aluminum side rails that are installed against the sides of the truck bed. The cover has handles on both of the long sides so that the user can lift the cover from either side of the truck bed. This may be a useful feature for people who need to open the cover quickly and do not want to have to keep going around the truck for one handle.
Shipping and Packaging
The UnderCover Tonneau Cover comes in two cardboard boxes with nylon strapping. Because the product is quite heavy, this packaging is sometimes insufficient. A package that is handled roughly may come with some damaged parts. Such as stripped screws, minor cuts, or aesthetic damage to the cover, scratching, or denting.
Users need to check the product closely when it arrives to make sure that the tonneau cover and the small plastic components are free of faults. Users should contact the company for replacement parts if some pieces were damaged during transit. However, shipping and manufacturing defects may make getting this product a hassle. Although the customer service team is responsive, the size and cost of the product may make returns somewhat difficult.
The installation of the UnderCover Ultra Flex Tonneau cover is relatively quick and easy. Users report that installation takes about 30 minutes. The only tool required is a socket wrench. The UnderCover company website has online videos that help supplement the written instructions that come with the product. To make sure that the cover aligns properly with the truck bed, customers should put the rails close to the back of the truck bed. And make sure the weather stripping on the sides of the cover overlaps the sides of the truck.
Performance and Technical Issues
The UnderCover Ultra Flex Tonneau Cover is attractive. It sits flush against the truck bed, creating a smooth, clean look. It also locks securely to the rails of the truck bed, so that things stored in the truck bed are safe and hidden. The cover is very sturdy and stable. Even a drive at high speeds does not cause the UnderCover Tonneau Cover to rattle.
There have also been reports that, over time, the finish on the cover starts to fade. In addition, the sides of the cover and the rubber seams between each piece of the panel may start to wear down and not create a proper seal anymore. This means that over time, the cover may become less watertight and water may leak into the truck bed.
It is also relatively high cost, hovering around $1,000. If the user receives a damaged cover, it may not operate as it should, and its high cost means that replacing the tonneau cover after one year may not be feasible.
Recommended or Not
Overall, the UnderCover Ultra Flex Tonneau Cover is recommended. The cover is very attractive for drivers who need a tonneau cover. It is sturdy, high quality, and fits flush against the truck bed.
The UnderCover Ultra Flex Tonneau Cover also has some nice features that are not available in comparable tonneau covers. The dual-action tailgate adds good quality of life features by allowing users to open and close the tailgate without having to lift or adjust the cover itself. For people who need to access things stored in the truck bed often, this can make opening and closing the tailgate much less of a hassle.
The cover also folds and can be propped fully upright, which can be useful if the user needs the truck bed to carry some taller items. But does not want to uninstall the cover or have it rattling against the truck while driving down the highway.
However, users should be aware of a few flaws. The cover may not be completely watertight, either due to gaps in the truck or eventually wearing down over time. Therefore, if a user needs to get a completely watertight seal, this cover may not be a good option.
The UnderCover Ultra Flex Tonneau Cover is a three-panel, aluminum tonneau cover. It has a few size, year, and finish options that make it customizable for a variety of truck owners. The cover has nice features such as either-side handles, three configurations from fully closed to fully open, and can be fully closed while operating the tailgate. It is mostly watertight if installed correctly with drain tubes. It has minimal leakage. Operates well when the components operate as they should.
