Getting into your truck shouldn't feel like climbing Mount Everest. That's why AMP Research invented the patented PowerStep, an automatic, electric-powered running board step that instantly extends when you open your truck door, and then hides itself safely out of sight when the doors close for improved ground clearance, aerodynamics and appearance. Its handsome design, all-weather performance and legendary reliability set the industry standard. The original AMP Research PowerStep electric steps are proven to perform in severe driving conditions and is backed by a full 5-year/60,000 mile warranty. The AMP Research powestep electric steps increase fuel efficiency by reducing the aerodynamic drag underneath the bottom of the vehicle.
