The alternator is responsible for generating electricity and keeping your battery charged while the engine is running. It powers critical systems such as headlights, climate controls, infotainment systems, fuel injection, and engine management electronics.
Moon Auto Parts stocks tested used alternators and professionally remanufactured alternators for domestic, import, gasoline, diesel, and heavy-duty vehicle applications.
Used alternators are removed from donor vehicles, inspected, tested for charging performance, and shipped ready for installation.
Remanufactured alternators are rebuilt with new bearings, brushes, voltage regulators, and internal wear components to meet OEM charging specifications.
The easiest way to identify the correct alternator is by providing your VIN. You can also locate the manufacturer part number on the alternator housing or rear identification label.
All alternators come with our 4-Year / 40,000-Mile Warranty, free shipping to commercial addresses, and no core charge on most units.
