The AMP Research PowerStep (75146-01A) is a complete pair of electric retractable running boards for the 2011-2014 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD with the diesel engine, in Extended Cab and Crew Cab. Each board drops down the instant a door opens and retracts flush under the cab a few seconds after the doors close.
Why owners choose it
- Auto-deploys the instant a door opens, then retracts flush under the rocker a few seconds after the doors close — out of sight when not in use.
- Extruded aluminum step board, 6 in. wide with a non-slip tread, rated to support 600 lb per side.
- Die-cast aluminum linkage with PTFE coating and stainless steel pivot pins resist corrosion.
- Weather-sealed electric motors and weathertight wiring connectors stand up to mud, salt, and all-weather use.
- Integrated LED step lights illuminate the step area at night.
- Hidden under the rocker when retracted for full ground clearance and a clean factory look.

Which AMP step fits your truck
This 75146-01A is cut for the diesel HD chassis, which routes the boards around the diesel exhaust and fuel systems. Gas-engine 2500/3500HD trucks and the light-duty 1500 use different PowerStep applications, so confirm your engine and cab before ordering.
