No custom brackets, modified wiring, or aftermarket charging system conversions are required.

The GM 92513882 Alternator is designed to replace the original factory alternator using the existing mounting locations, electrical connections, and serpentine belt arrangement.

Its factory-style construction and internally regulated charging system make it an ideal replacement for owners who want to maintain their vehicle’s original charging system configuration.

Brand New – Not Remanufactured

Many replacement alternators available today are remanufactured units that reuse previously installed housings and internal components.
