The Extang Solid Fold ALX is a hard, tri-fold tonneau cover for 2014–2018 (2019 legacy/limited) Chevy Silverado and GMC Sierra 1500 with a 5 ft 9 in bed. It uses textured matte TPO panels and snap-on seals for weather resistance and an OEM-style look, and ships fully assembled for quick installation. One-inch EnduraShield panels resist dents, scratches and UV fading, support 600 lbs evenly, and a rotary "twist & lift" release operates without tailgate clamps.
