AMP Research invented the PowerStep, the automatic, electric-powered running board that instantly extends when the car door is opened and retracts out of sight when the doors close for improved ground clearance, aerodynamics, and appearance. Its sleek design, all-weather performance, and legendary reliability set the industry standard. PowerStep has die-cast aluminum alloy components and precision stainless steel pivot pins for rock-solid stability. The original PowerStep is American designed and engineered.
