Shop 2020 GMC Sierra running boards, nerf bars, and drop steps by matching the exact Sierra series, cab configuration, and product application shown on the individual product page. The visible live assortment is Sierra 1500-focused, so do not assume 2500HD or 3500HD fitment unless a listing explicitly names that truck.
Choose the Correct 2020 Sierra Step
Confirm the exact truck series and cab first because Crew Cab, Double Cab, and Regular Cab applications can use different board lengths, brackets, and mounting points. Then compare running boards, nerf bars, hex steps, drop steps, wide-access designs, dimensions, finishes, and package contents supported by the individual listing.

2020 GMC Sierra Running Boards FAQ
Does every product on this page fit every 2020 GMC Sierra?
No. The exact Sierra series, cab configuration, mounting application, and product design must match. Use the individual product page as the controlling fitment source.
Do Crew Cab, Double Cab, and Regular Cab steps interchange?
Do not assume so. Cab dimensions can change board length, bracket placement, mounting points, and step location. Choose a product that specifically supports the truck’s cab configuration.
How should I compare running boards, nerf bars, hex steps, and drop-step designs?
Match the exact vehicle and cab first, then compare stepping surface, profile, dimensions, material and finish details, and package contents. Style or appearance alone does not determine compatibility.
What should I verify before installation or ordering a bundle?
Check the exact Sierra series, model year and cab, mounting application, included brackets or hardware, package contents, and installation notes. For bundled products, verify any additional bed or vehicle requirements; do not assume drilling requirements or factory mounting-point use unless the product page states it.
