The AMP Research PowerStep XL (77154-01A) is a complete pair of electric retractable running boards for the 2014-2019 Chevrolet Silverado and GMC Sierra 1500 Crew Cab and the 2015-2019 Silverado and Sierra 2500HD/3500HD 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 2014-2018 Silverado/Sierra 1500 Crew Cab (plus the 2019 Silverado 1500 LD / Sierra 1500 Limited old-body carryover) and 2015-2019 Silverado/Sierra 2500HD/3500HD Crew Cab, gas engines only.

How the PowerStep XL differs

The XL adds about 3 inches of extra drop for lifted and leveled trucks. The prior 2007-2014 Silverado/Sierra Crew Cab uses AMP PowerStep XL 77126-01A, and the 2022-2026 1500 uses 77255-01A — confirm whether your 2019 truck is the old-body LD/Limited or the new body before ordering.

FAQ

Does the 77154-01A fit a 2019 Silverado 1500?

It fits the 2019 Silverado 1500 LD / Sierra 1500 Limited (old-body carryover) Crew Cab, not the 2019 new-body 1500.

Does it fit a diesel 2500HD?

No. HD applications are listed for gas engines only.

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.
