The AMP Research PowerStep Xtreme fits the 2015-2019 GMC Sierra 3500HD and drops down automatically when the doors open for easy cab access in extreme conditions.
Product Overview
The PowerStep Xtreme is a heavy-duty electric running board built for mud, snow, and off-road abuse. It extends when a door opens and retracts flush to the rocker panel when closed, keeping ground clearance intact on your Sierra 3500HD.
Weather-sealed motors and reinforced linkage handle harsh conditions the standard PowerStep isn't rated for. Plug-and-play OBD wiring means no splicing into the factory harness.
