UnderCover Tonneau Covers

It was nearly half the weight of a fiberglass shell, yet it delivered exceptional strength and reliability.

What Makes UnderCover Stand Out

There is a variety of quality tonneau covers on the US market. So what makes UnderCover so special, and why do truck owners prefer these bed covers to the others? Let’s dive deeper into the details.

  • Strong yet lightweight. ABS composite combined with the aircraft-grade aluminum provides the perfect balance of weight and durability. These materials will not rust or corrode, as they are resistant to UV impact, humidity, and temperature changes. Therefore, such an investment will serve you well for years to come.
  • X-Effect design. Patented internal bracing ensures structural integrity and prevents sagging over time. This feature makes these truck bed covers truly special.
  • Premium aesthetics. From textured matte finishes to painted-to-match covers like the Elite LX and LUX, UnderCover products complement the look of your truck. The finish looks right on the truck regardless of its color and complements the other black exterior elements. Besides, these tonneau covers do not change the vehicle profile, which is also important.
  • Weather-resistant engineering. EPDM seals, water-drainage systems, and reinforced hinges keep the bed dry in rain, snow, and heat. And even though Real Truck, the official manufacturer of UnderCover tonneau covers, does everything possible to ensure maximum protection against humidity and water, let’s be honest. 100% waterproof tonneau covers are not available on the US market at this moment.
  • Smart bed access. Whether you prefer a one-piece lift or a folding tri-panel setup, you’ll get full access in seconds. The user’s convenience and hassle-free operation are the ultimate priorities for the manufacturer, and you can perfectly feel it when you start using your new tonneau cover.
  • Multiple configurations. LED lighting, carpeted undersides, locking systems, or toolbox compatibility — it’s you who chooses what fits your lifestyle. See detailed descriptions for different models, as the configurations differ from model to model. 
  • Warranties that matter. The tonneau covers are backed by 3-year or limited lifetime warranties by the official manufacturer, depending on the model. Yes, this is protection that lasts.
