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.

Fitment

Fits the 2022-2024 Toyota Tundra CrewMax, both the gas i-FORCE and the i-FORCE MAX hybrid. Does not fit the Double Cab.

Which PowerStep fits your truck

This 78338-01A is the heavy-duty PowerStep Xtreme for the Tundra CrewMax. The full-length-LED Vision (96338-01A) fits the same truck if you want integrated lighting — both are CrewMax-only.

FAQ

Does the 78338-01A fit a Double Cab Tundra?

No. It fits the 2022-2024 Tundra CrewMax only. It does fit both the gas i-FORCE and the i-FORCE MAX hybrid.

How does it wire up and does it require drilling?

The kit uses a vehicle-specific plug-in OBD-II harness, so there is no wire cutting or splicing. Some cab configurations require trimming the board to length or drilling per the install guide, and professional installation is recommended.

Is this PowerStep sold as a pair?

Yes. This part number includes both the driver- and passenger-side assemblies as a complete two-side kit.

What warranty does AMP Research provide?

AMP backs the PowerStep with a 5-year/60,000-mile limited warranty against defects in materials and workmanship.
