GMC Sierra Door Sills

Stainless steel with a brushed finish gives a stylish look to any part of your GMC Sierra pickup, as the 1999-2018 door sills you’ll find on AmericanTrucks prove. Fitting easily and precisely onto your pickup’s threshold area, these sills are manufactured from quality materials and provide protection to the surface beneath them as well as a refreshing boost to your cab’s aesthetics. Brushed stainless is the most common finish, but there are other choices, as well – such as the riveting, dark glisten of the “black platinum” finish on some of the sills you’ll find on this site. You can also choose between plain sill pieces, and those laser-etched with the GMC logo, so that you can express your brand loyalty or just add a bit more detail to the sills.
