Extang 20-23 Chevy/GMC Silverado/Sierra 2500/3500HD 6.9ft. Bed Endure ALX

This is the Extang Endure ALX hard folding tonneau cover, specifically made for your 2020-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with a 6.9-foot bed. It's designed to give you a clean, low-profile look when closed, while still offering full access to your truck bed when you need it. The Endure ALX is built with four TPO-coated panels that create a strong, seamless cover.

Each panel is about half an inch thick and sits on a lightweight aluminum frame. This construction makes the cover strong enough to hold up to 500 pounds of evenly distributed weight, and it's built to resist scratches, dents, and fading from the sun. The frame around the edges has a matte black powder coat finish, and there are seals along every seam to keep water and dust out of your truck bed. A standout feature is Extang's exclusive Secure Rotary Latch System, which lets you open the cover with just one hand by twisting and lifting. It automatically locks when you close it, adding a good layer of security for your cargo.

When you need to haul larger items, the Endure ALX folds up easily against the cab in seconds, giving you complete bed access. Installation is straightforward and can typically be done in about 30 minutes with basic tools. Extang backs this cover with a limited 5-year warranty.
