Ultra Flex






A hard folding truck bed cover that comes with overwhelming new features, and is topped off with an alluring matte finish. The Ultra Flex is in a category of its own. From the irresistible outward appearance, to each component beneath the cover, the Ultra Flex has been carefully crafted to be the ultimate all-purpose truck bed cover.

All-new features that accompany the Ultra Flex include a SaddleBag storage box for convenient out-of-the-way bed organization, dual rail LED bed lighting system for enhanced night vision, and a universal tailgate seal, allowing you to close the tailgate with the cover up or down. Multiple riding positions allow the user to ride with full access to their bed, and full weather protection is available if the cover is in the fully closed position. Ultra Flex is a no-drill application and can be installed and removed easily with our newly designed L-Rail’s. What’s more, the Ultra Flex is backed by a 5-year warranty, making it the most desirable folding cover on the market.
