GMC Sierra 1500 Tonneau Cover - UnderCover Elite LX - Abalone White (2016–2018). A color-matched, hard tonneau built for a precise fit on 6 ft 6 in beds.
The Elite LX uses lightweight ABS composite for strength without added bulk, then adds a premium carpet-lined underside and factory Abalone White finish (G1W/WA140X). Quick-release hardware lets you remove it when needed, while a full perimeter seal and a removable LED light boost daily convenience and weather protection. Designed to complement your Sierra’s lines, it helps keep cargo secure and the bed clean.
