The AMP Research PowerStep Xtreme (78338-01A) is a complete pair of electric retractable running boards for the 2022-2024 Toyota Tundra CrewMax. Each board deploys the instant a door opens and retracts flush under the rocker 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.
AMP's heavy-duty PowerStep: a reinforced die-cast aluminum linkage with stainless steel pivot pins for extra durability.
Extruded aluminum step board, 6 in. wide and cab-length, with a non-slip tread rated to support 600 lb per side.
Integrated LED step lights illuminate the step area at night.
Vehicle-specific plug-in OBD-II wiring harness installs with no wire cutting or splicing.
Hidden under the rocker when retracted for full ground clearance and a clean factory look.

What's included

Sold as a complete kit for both sides of the truck. Includes the driver- and passenger-side PowerStep Xtreme assemblies with motors, a vehicle-specific plug-in OBD-II wiring harness and control module, mounting brackets and hardware, integrated LED step lights, and an installation guide. Some cab configurations require trimming the board to length; professional installation is recommended.
