How you know

Height is the usual reason, particularly on lifted or heavy duty trucks. On a mid-size SUV, second and third row configuration, rear climate and towing content all change part numbers here.

Buying OEM, briefly

• GM stands behind it. The running boards and steps warranty comes from the manufacturer, not from us.
• Priced below the dealer. Running Boards and Steps at up to 40 percent off list, with no membership.
• Factory sourced. These running boards and steps are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical running boards and steps numbers for you.
• Ships from Dallas. Running Boards and Steps ordered by 3pm Central go out the same business day.

Confirming fitment

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
