Chevrolet Silverado 3500 HD Tonneau Cover - Extang - Endure ALX - Matte black - `07-`14. The Extang Endure ALX is a low-profile, folding hard tonneau designed for 2007–2014 Silverado 3500 HD (6'6" bed without Cargo Management System). It combines durable construction with user-friendly operation for owners who need reliable bed protection and easy access.
The Endure ALX uses four patented EnduraShield TPO-coated panels mounted on a lightweight aluminum frame. Each panel is approximately ½" thick, delivering structural rigidity while keeping weight down. The cover supports up to 500 lbs of evenly distributed weight and resists scratches, dents, and UV-related fading thanks to a rugged matte black powder coat and EnduraCoat finish. Reinforced extruded weather seals around the perimeter help keep water and dust out, and the Extang Secure Rotary Latch System provides one-handed twist-and-lift operation with automatic latching. When you need full bed access, the panels fold up toward the cab for quick, unobstructed loading. Installation is straightforward and can be completed with basic tools in a driveway or garage; the product is backed by a limited 5-year warranty.
