2021-2026 GM SUV PowerStep Black (AMP76327-01A)Getting into your SUV shouldn't feel like climbing Mount Everest. That's why AMP Research developed the PowerStep, the automatic, electric powered running board specifically designed for Chevrolet Suburban, Tahoe, and Cadillac Escalade models. These steps instantly extend when you open your door, providing a natural step height, and then hide themselves safely out of sight when the doors close to improve ground clearance, aerodynamics, and appearance.
