GMC Sierra Tonneau Cover - Extang - Endure ALX - Matte Black - `19-`26 is a low-profile folding bed cover built to protect cargo while preserving the truck's factory lines. Made for 2019–2026 GMC Sierra 5'9" beds (without CarbonPro and without factory side storage boxes), it balances strength and everyday convenience.
The Endure ALX uses four EnduraShield TPO-coated panels on lightweight aluminum frames to deliver durable, scratch- and UV-resistant coverage for the bed. Each panel is approximately ½" thick and the assembly supports up to 500 lbs. of evenly distributed weight, while the matte black powder-coated perimeter frame and hardware resist wear. Extruded weather seals at seams help keep water and debris out, and the Extang Secure Rotary Latch System offers one-handed, twist-and-lift access with automatic latching for added security. When you need full bed space, the cover folds up toward the cab for unobstructed access. The unit is backed by a limited 5-year warranty and is designed for straightforward installation.
