Chevrolet Silverado 3500 HD Tonneau Cover - Extang Endure ALX (Matte Black) — 2020-2026. A low-profile, folding hard cover engineered to protect your bed and cargo while keeping full-access capability when needed.
The Endure ALX combines four patented EnduraShield TPO-coated panels with a lightweight aircraft-grade aluminum frame for a rigid, durable assembly. Each panel is ½" thick and the perimeter frame and hinges are finished in a textured matte black powder coat for added wear resistance. The cover supports up to 500 lbs of evenly distributed weight, resists scratches, dents and UV-related fading, and uses extruded weather seals to keep out the elements. Extang’s Secure Rotary Latch System offers one-handed twist-and-lift operation and automatically latches for reliable closure. When maximum bed space is required the cover folds up to the cab quickly, and the unit is backed by a limited five-year warranty. Installation is straightforward with basic tools in about 30 minutes, or take advantage of our professional install.
