Description

Getting into your truck shouldn't feel like climbing Mount Everest. That's why AMP Research invested in POWERSTEP, the automatic, electric-powered running board that instantly extends when you open your 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.
