OEM GM Alternators

Refine Results

If you notice a loss of power, it may not be a bad battery; it may be a failing alternator. (All you need to know about alternators here.) Alternators are made to last a long time, but they are not infallible, so should you need a new one, buy an OEM GM alternator.

  • An OEM GM alternator will be an exact fit for your model. All of the bolt holes will line up and will be the right size.
  • An OEM GM alternator will be able to handle the power load your GM requires, so it is optimized to keep your battery charged no matter which model you drive.
  • GM alternators are made from quality materials that last as long as the original parts.

When you buy your GM parts from us, you get our price match guarantee on genuine GM parts, which means you get the lowest price shipped to your door. We also offer free parts lookups.  Find the right GM alternator for your vehicle today.
