GMC Sierra 3500 Tonneau Cover - Extang Endure ALX - Matte Black - '15-'19. A low-profile folding tonneau engineered to protect your cargo without adding bulk, offering quick access and durable weather protection for 2015–2019 Sierra 3500 models (6'6" bed).
The Endure ALX uses four TPO-coated EnduraShield panels mounted on a lightweight aluminum frame to deliver impressive rigidity and scratch resistance. Each panel is about 1/2" thick and the assembly supports up to 500 lbs of evenly distributed weight. The perimeter frame is finished in matte black powder coat and fitted with extruded weather seals to guard against water and dust. Extang’s Secure Rotary Latch System provides one-handed, twist-and-lift operation and automatically latches for convenience and security. When you need full bed access, the cover folds up to the cab quickly and stays open for loading larger items. Extang backs the design with a limited 5-year warranty.
