Steelcraft’s team of designers and engineers works non-stop to keep the company’s products ahead of the pack and to lead with new designs and features, making their 1999-2017 exterior parts an effective choice when improving your Sierra. Focusing on bumper and grille parts, plus a good range of side steps, Steelcraft aims at making drill-free components that are stable and rock-solid anyway. Their 2014-2017 brush guards feature protective rubber strips, removable headlight guards, and similar details. On the heavier duty side, Steelcraft also makes 1999-2013 and 2014-2017 bull bars, which are often made one-piece for extra robustness. They may also have extras such as removable skid plates to protect the front underside of your vehicle, and pre-drilled holes where you can mount auxiliary lighting if desired. American Trucks also sells plenty of their highly varied 1999-2017 crew cab and double cab side steps. Most of these products come with a 2 year limited warranty from Steelcraft.
