Common Questions
Does this fit my Cummins diesel Ram 2500?
No. This SKU is gas-engine only. Cummins-equipped Ram 2500/3500 trucks require a different AMP PowerStep part number (76239-01A).
How long after I close the door does the step retract?
Approximately 3 seconds.
Can I use this to access my roof rack?
Yes. The steps are pressure-sensitive — you can hold the step deployed by applying foot pressure while closing the door, useful for accessing roof-mounted cargo.
The Obsidian Take
The PowerStep (76243-01A) is for the 2019–2022 Ram 2500/3500 gas owner — any cab style — who wants a clean, factory-style automatic step. Die-cast aluminum, 600-lb rating, OE-quality motors, 5-year/60,000-mile warranty, no wire splicing, roughly 3-hour install.
The hard check before ordering: confirm your engine is gas, not Cummins diesel. That's a confirmed, non-negotiable lockout — order 76239-01A instead if you have the diesel.
Non-Returnable Notice: Once wiring is connected and the unit is powered, this system is non-returnable per AMP Research policy. Confirm engine type and model year before ordering.
