GMC Sierra 3500 HD Bed Cover – UnderCover LUX – Iridium Effect (2015–2019). This factory-painted, one-piece hard tonneau is built for the 6 ft 6 in standard bed and delivers secure, weather-resistant coverage with a refined OEM match.

The LUX is painted in GMC’s Iridium Effect to code GXG/WA121V for a true color match. Its low-profile contour with subtle spoiler and styled ribs complements the Sierra while the full-perimeter seal helps keep out rain and dust. Weatherproof twist locks add straightforward security, and the included LED cargo light brightens the bed when you need it. A lightweight design allows quick, no-tool removal when hauling tall loads. Please verify bed length and paint code before ordering.
