The AMP Research PowerStep is an automatic, electric-powered running board that simplifies vehicle entry and exit without compromising ground clearance or aerodynamics. The system instantly extends when a door is opened and retracts flush under the rocker panels when doors are closed, providing a sleek, integrated appearance and reduced drag.

Engineered for all-weather reliability, these steps are constructed from high-strength, die-cast aluminum alloy. Each component features a military-spec, PTFE-coated finish to ensure long-term corrosion resistance in harsh environments. The assembly utilizes precision stainless steel pivot pins for rock-solid stability and maintenance-free, self-lubricating bushings for consistent operation across all seasons.
