A GMC Sierra is an impressive vehicle built to perform and to stand out for its looks. Your truck is only as good as its customizations, though, and adding upgrades and accessories from American Trucks is a simple way to make your Sierra into the truck of your dreams. While we take care to offer realistic photos of our parts, it can be helpful to see upgrades installed on a customer's truck. That's why we created this customer photo gallery below. Look through photos of bed covers, LED lights, wheels, and more installed on fellow GMC Sierra model trucks. These photos are submitted by real people, so you'll know exactly what they look like. Hopefully, this gallery helps you decide what upgrades you want yourself, and you might even add upgrade photos of your own once you add that new lift kit or whatever improvement you want.
