With pickup trucks getting bigger, it becomes more challenging to get in and out. Of course, different kinds of assist steps are part of standard equipment on many of the truck models and trim levels. If your 2021 GMC Sierra did not come from the factory with these useful accessories, or if the stock setup does not suit your taste and needs, you will find the right design at our online store. We have 2021 GMC Sierra 1500 running boards for any budget and styling preferences. Aside from traditional options, here you'll find retractable side steps powered by an electric motor end equipped with a control module, which automatically deploys the boards when you open the door.
Whether you want to give your truck a more aggressive, off-road-ready look or are searching for an unobtrusive pair of step boards that will blend with its exterior and look like a factory setup, we've got you covered. Because these add-ons are manufactured from strong, non-corrosive materials, you don't have to worry about durability. These include aircraft-grade aluminum and stainless steel, while those constructed from carbon steel are powdercoated to remain rust-free for years to come. Most of the running boards are custom designed to fit your light-duty Sierra, ensuring no-drill bolt-on installation using application-specific brackets.
