The all new Pro X15 includes many of the same great features as our #1 selling cover, the Lo Pro, but with added style and performance. New 15 degree rails deliver an Xtra-low profile, flush-mount look on the truck bed, and superior-grade woven fabric provides a stylish matte-black appearance. The cover can be installed or removed in minutes, with no drilling required, and the unique self-leveling design feature allows for a more accurate installation. The Pro X15 is made in the USA and comes backed with a Lifetime Warranty.\nPro X15 Tonneau Cover - 2020-2021 Chevy Silverado/GMC Sierra 2500 HD/3500 HD 6' 9" Bed without MultiPro Tailgate\nBefore purchase please verify if you have New Body Style or Legacy (Chevy)/Limited (GMC) on 2019 Silverado/Sierra 1500 -- This part is for the New Body StyleNOTE: Will NOT fit with MultiPro Tailgate\n2020-2021 Chevrolet Silverado 2500 HD 82.2 Bed Without MultiPro Tailgate, 2020-2021 Chevrolet Silverado 3500 HD 82.2 Bed Without MultiPro Tailgate, 2020-2021 GMC Sierra 2500 HD 82.2 Bed Without MultiPro Tailgate, 2020-2021 GMC Sierra 3500 HD 82.2 Bed Without MultiPro Tailgate
