The AMP Research PowerStep XL (77137-01A) is a complete pair of electric retractable running boards for the 2007-2021 Toyota Tundra CrewMax. It extends about 3 inches lower than the standard PowerStep for easier entry into a lifted or leveled truck.

Why owners choose it

Extends about 3 inches lower than the standard PowerStep, so stepping into a lifted or leveled truck takes far less of a climb.
Auto-deploys the instant a door opens, then retracts flush under the rocker a few seconds after the doors close — hidden and out of the way when not in use.
6-inch wide, cab-length aluminum step board with a non-slip tread, rated to support 600 lb per side.
Anodized aluminum with a military-grade PTFE (Teflon) coating and stainless steel pivot pins resists 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 truck. Includes the driver- and passenger-side PowerStep XL assemblies with motors, vehicle-specific mounting brackets and hardware, a wiring harness, integrated LED step lights, and an installation guide. On most late-model trucks AMP's Plug-N-Play module connects to the OBDII port with no wire splicing. AMP recommends professional installation.

FAQ

Does the 77137-01A fit a Tundra Double Cab?

No. It is cut for the larger CrewMax cab only, not the Double Cab.

What is the difference between the PowerStep XL and the standard PowerStep?

The PowerStep XL extends about 3 inches lower than the standard PowerStep, making a lifted or leveled truck easier to climb into. Both use the same 6-inch aluminum step, 600 lb-per-side rating, integrated LED lights, and auto deploy/retract; the XL just drops farther.

Is the PowerStep XL sold as a pair?

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

What warranty does AMP Research provide?

AMP backs the PowerStep with a 5-year limited warranty against defects in materials and workmanship.
