GMC Sierra Bed Rails & Caps

While it’s often said that “form follows function,” you don’t need to make a choice with the 1999-2018 GMC Sierra bed rails on AmericanTrucks, because they both work great and look great, too! There are several choices available as far as they go – you can pick nylon and stainless steel versions, or all stainless steel types, for your truck. Those with nylon ends are more affordable, but have a maximum tie-down capacity around 500 lbs. All-stainless bed rails may cost more, but they also offer you tie-down capacities as high as 1,000 lbs. They’re all designed for a sleek, streamlined look that goes well with the modern body lines of the Sierra’s layout. In addition, some of them have special features such as pop-up tie-down rings that are out of sight when not needed, so as not to interrupt the flow of the design, but which can be folded up whenever you need a secure fastening!
