Make entering and exiting your Ram 2500/3500 easier with the AMP Research 78139-01A PowerStep Xtreme, designed to automatically deploy and retract electronically. The AMP Research PowerStep Xtreme is a retractable electric-powered running board that instantly extends when you open the door. Once the door is closed, it then hides itself safely out of sight for improved ground clearance, aerodynamics, and appearance. With a dual motor design, the PowerStep Xtreme is twice as strong as the original. PowerStep Xtreme sets the industry standard with an aggressive design for extreme traction, all-weather performance made from high-strength, die-cast aluminum components. Envisioning the most punishing environments, AMP Research engineered PowerStep XTreme for legendary reliability with its durable, high-textured powder-coat finish to resist corrosion and maximize grip.

PowerStep Xtreme is Invented, engineered, and built in America, and has been tested and proven to perform in all conditions. The heavy-duty dual motors drive the Xtreme Running Board to deliver more power when deploying, and retracting. Engineered to support loads up to 600 lbs. The heavy-duty OEM quality electric motor provides decades of reliable, maintenance free operation and the stainless steel hinge points and bearings ensure flawless performance. These lightweight, yet rock-solid running boards feature rugged die-cast linkage components that are made in the USA of aircraft-quality aluminum and a high-texture black coating for maximum corrosion protection in the snow, ice, dust, mud, and dirt. The Xtreme design, all-weather performance, and legendary reliability set the industry standard.

The AMP Research Plug-N-Play System simplifies the installation of your PowerStep Xtreme Running Boards. Designed to make installation a breeze, the innovative Plug-N-Play harness eliminates the need gain access behind the door panels during installation. This not only saves time during installation, but also eliminates the need to remove interior components.
