GMC Sierra Running Boards & Nerf Bars FAQ
How do I verify fitment for my GMC Sierra?
Match the product page to your exact Sierra model year, model designation, and cab or door configuration before ordering. Also confirm any body, wheelbase, bracket, mounting, or trim limits shown on the individual product page.
Are Regular Cab, Extended Cab, Double Cab, and Crew Cab step products interchangeable?
No. Different Sierra generations and cab configurations can use different board lengths, brackets, mounting layouts, and step placement, so match the exact application stated on the listing.
How should I compare the styles in this collection?
Confirm fitment first, then compare the stated width, profile, step position, material, finish, dimensions, and cab coverage. Similar-looking 5-inch, 6-inch, wider running-board, aluminum, and drop-step designs should not be treated as interchangeable based on style alone.
What should I check before ordering or installation?
Review package quantity, included brackets or hardware, mounting requirements, dimensions, exclusions, and installation notes on the individual product page. Do not assume no-drill installation or that all hardware is included unless the listing specifically confirms it.
