Product Description

The AMP Research PowerStep™ Xtreme (part 78139-01A) is engineered for the harshest environments and designed to deliver dependable performance for 2013-2017 Ram 2500 and 3500 trucks. This heavy-duty power-deploying step system features dual motors per side, ensuring fast and reliable extension under extreme conditions, while integrated LEDs enhance visibility when entering or exiting the vehicle.

Constructed from die-cast aircraft-grade aluminum and coated with a military-grade powder finish, the PowerStep Xtreme stands up to corrosion, ice, mud, and rough terrain. The 6-inch wide, textured step provides safe footing, and the boards retract automatically to preserve ground clearance. Installation is simplified via a Plug-N-Play harness (connects to the OBD-II port) and includes all necessary hardware, bracketry, and instructions. A robust 5-year/60,000-mile warranty backs its durability.
