Description
Owners of standard-bed Silverado and Sierra trucks need the 6-foot-6-inch length, not the short or eight-foot Extang variant. Solid Fold ALX 88450 is catalogued for this GM standard-bed dimension.
A durable tri-fold of one-inch EnduraShield TPO surfaces resists scratching and UV exposure. With a rotary tailgate release and tool-free Jaw-Grip front clamps, the cover allows useful cargo access without drilling the bed rails. Extang states a 600-lb evenly distributed panel rating.
