The AMP Research PowerStep Xtreme (78122-01A) is a complete pair of heavy-duty dual-motor electric retractable running boards for the 2007-2018 Jeep Wrangler JK 4-Door (Unlimited/JKU). Each board auto-deploys the instant a door opens and retracts flush under the rocker off-road.
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.

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.
