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.
