Common Questions
Does this fit a standard-wheelbase Expedition?
No. This kit is built specifically for the Expedition MAX's longer wheelbase and correspondingly longer rocker panel. Standard Expedition has different mounting points.
Does it require cutting or splicing into factory wiring?
No. The plug-and-play module interfaces with the factory door-trigger circuits without cutting or splicing, keeping your factory Ford warranty intact.
What's included for LED lighting?
Integrated low-profile LED courtesy lights are standard with this kit — no separate purchase required.
The Obsidian Take
The PowerStep (76337-01A) is for the 2020–2021 Expedition MAX owner who wants a clean, factory-style automatic step that disappears when not in use — die-cast aluminum, 600-lb rating, anti-pinch protection, 5-year/60,000-mile warranty, no wire splicing.
One thing to confirm before ordering: your Expedition is the extended-wheelbase MAX, not standard wheelbase — check your rear door and wheel well relationship if unsure.
Non-Returnable Notice: Once wiring is connected and the unit is powered, this system is non-returnable per AMP Research policy. Confirm wheelbase before ordering.
