GMC Sierra 3500HD Tonneau Cover - UnderCover Elite LX - Glory Red (`15-`19). This premium, color-matched hard cover is designed for 2015–2019 Sierra 3500HD trucks with the 6'6" bed, providing durable protection and a precise, model-specific fit.
Built on the proven Elite platform, the LX adds a plush carpet-lined underside and a paint finish matched to GM Glory Red (GPJ/WA434B). Its lightweight ABS-composite construction resists dents and corrosion, while the full-perimeter seal helps keep out dust and rain. Quick-release hardware enables fast, tool-free removal when you need full bed access, and the included removable LED light illuminates cargo after dark. Carefully contoured for a clean, integrated look on the Sierra’s bed rails.
