The AMP Research PowerStep Xtreme (78139-01A) is a complete pair of heavy-duty dual-motor electric retractable running boards for the 2013-2017 Ram 2500 and 3500 in all cab configurations. Each board auto-deploys the instant a door opens and retracts flush under the rocker.

Why owners choose it

Dual-motor design (two motors per side) delivers heavy-duty deploy/retract power built for frequent use and harsh climates.
Auto-deploys the instant a door opens, then retracts flush under the rocker a few seconds after the doors close.
6-inch wide, cab-length aluminum step board with a non-slip tread, rated to support 600 lb per side — about twice the capacity of most other steps.
Rigid cast aluminum with stainless steel hinge pins, anodized and coated with a military-grade PTFE (Teflon) finish to resist corrosion.
Integrated LED step lights illuminate the step area at night.
Retracts flush for full ground clearance and a clean factory look.

What's included

Sold as a complete kit for both sides of the vehicle. Includes the driver- and passenger-side dual-motor PowerStep Xtreme assemblies, vehicle-specific mounting brackets and hardware, a wiring harness, integrated LED step lights, and an installation guide. Newer applications use AMP's Plug-N-Play OBDII module. AMP recommends professional installation.

FAQ

Does the 78139-01A fit a Ram 1500?

No. It fits the Ram 2500 and 3500 HD only, not the Ram 1500.

Does it fit a Mega Cab with air suspension?

No. Mega Cab trucks with factory air-ride suspension are excluded.

What makes the PowerStep Xtreme different from the standard PowerStep?

The Xtreme uses a dual-motor design (two motors per side) and reinforced cast-aluminum construction for heavy use and harsh climates, versus the single motor per side on the standard PowerStep. Both carry a 600 lb-per-side rating, integrated LED lights, and auto deploy/retract.

Is the PowerStep Xtreme sold as a pair?

Yes. This part number is a complete two-side kit with both the driver- and passenger-side PowerStep Xtreme assemblies.
