Detailed Product Description

This alternator, part number 8489, is a remanufactured unit from BBB Industries' REMAN ALTERNATOR line, designed specifically for Chevrolet and GMC heavy-duty trucks such as the Sierra 2500 HD Classic and Silverado 3500 Classic. The 145-amp rating ensures sufficient electrical output to support vehicle systems under heavy load conditions. Featuring an air cooling method and an internal fan, it maintains optimal operating temperatures during extended use.

The included clutch pulley with six grooves is designed for serpentine belt systems, reducing vibration and wear on the drivetrain. The internal voltage regulator maintains stable voltage output, while the negative polarity and 12 o'clock plug clock position ensure compatibility with the specified vehicle models. This alternator is not brushless, relying on a traditional brush system consistent with the original equipment manufacturer (OEM) design by Delco/Delphi.
