This AMP Research 79-inch 2‑rib replacement step assembly is a direct component of the patented PowerStep system, the automatic running board that extends when doors open and retracts when closed. Built for all‑weather reliability, it uses high‑strength die‑cast aluminum components with corrosion‑resistant finish, self‑lubricating bushings and precision stainless pivot pins. The 79‑inch step is black and matches OEM PowerStep performance.
