The AMP Research PowerStep Xtreme fits the 2023-2026 GMC Sierra 3500HD and delivers heavy-duty retractable running boards built for the harshest conditions.
Product Overview
The PowerStep Xtreme is a motorized side step that deploys when the door opens and retracts when it closes. It is engineered for owners who face sub-zero winters, deep mud, and caked-on debris that wreck standard running boards.
For the Sierra 3500HD, this means a clean rocker profile when driving and a reliable step when climbing into the cab after a long day on the job site.
