The AMP Research PowerStep XL (77255-01A) is a complete pair of electric retractable running boards for the 2022-2026 Chevrolet Silverado and GMC Sierra 1500 Crew Cab. 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.

Fitment

Fits 2022-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 Crew Cab (gas and diesel). Does not fit Double Cab or Regular Cab.

How the PowerStep XL differs

The XL adds about 3 inches of extra drop for lifted and leveled trucks. AMP also offers a standard-height Plug-N-Play PowerStep, 76255-01A, for the same trucks; the prior-generation 2014-2019 Silverado/Sierra 1500 Crew Cab uses AMP PowerStep XL 77154-01A — confirm your model year before ordering.

FAQ

Does the 77255-01A fit a Double Cab?

No. It is cut for the Crew Cab only, not the Double Cab or Regular Cab.

What is the difference between the 77255-01A and the 76255-01A?

Both fit the 2022-2026 Silverado/Sierra 1500. The 77255-01A is the PowerStep XL with about 3 inches of extra drop for lifted trucks; the 76255-01A is the standard-height Plug-N-Play PowerStep.

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.
