GMC Sierra Tonneau Cover - Extang - Endure ALX - Matte Black - `14-`18. A low-profile, folding aluminum tonneau designed for truck owners who want durable protection and convenient bed access without bulk.
The Extang Endure ALX uses four rigid, TPO-coated panels with a lightweight aluminum frame to deliver strength and low weight. Its matte black powder-coated frame resists wear while extruded weather seals protect cargo from the elements. The Endure ALX folds forward for full bed access, and when closed it mounts flush with the bed rails for a tidy appearance. The tail features Extang’s Secure Rotary Latch System for one-handed twist-and-lift operation and reliable closure. Engineered to carry up to 500 lbs of evenly distributed weight, the construction resists dents and UV-related fading for long-term use.
