AMP Research 1999-2006 Chevy/GMC Silverado/Sierra Extended/Crew PowerStep - Black - 75113-01A

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