Shop running boards and nerf bars for 2019, 2020, 2021, 2022, 2023, 2024, 2025, and 2026 GMC Sierra trucks. People Auto Parts carries aftermarket side steps for Sierra Regular Cab, Double Cab, and Crew Cab models, including black, stainless, 5-inch, 6-inch, and drop step styles.

Cab fitment is important when choosing GMC Sierra running boards. A set made for a Crew Cab may not fit a Double Cab or Regular Cab truck, and product length, brackets, and mounting points can vary by configuration. Before ordering, confirm your model year, cab style, and the fitment notes on the individual product page.

Choose 5-inch running boards for a clean side-step profile, 6-inch steps for a wider stepping surface, or drop step nerf bars for a lower step pad and more rugged look. All products in this collection are aftermarket parts and are not OEM or OE GMC parts. GMC and Sierra names are used only to identify vehicle compatibility.
