Upgrade your Mopar charging system with this Chrysler Square Back 100 amp alternator designed to deliver dependable charging performance for classic muscle cars, street rods, restoration projects, and custom builds. Featuring a durable aluminum housing, internal voltage regulator, V-belt pulley, and one-wire capable design, this alternator provides the charging capacity needed to support modern electrical accessories while maintaining a clean chrome appearance.

The 100 amp output provides a significant increase in charging capacity over many factory charging systems and helps support electric cooling fans, electric fuel pumps, upgraded ignition systems, aftermarket lighting, air conditioning systems, audio equipment, and fuel injection conversions. Increased charging capacity helps maintain stable system voltage during idle, cruising, and stop-and-go driving conditions.

Compatible with many Chrysler Small Block and Big Block applications, including 273, 318, 340, 360, 361, 383, 400, 413, 426 Hemi, and 440 engine combinations, this alternator is commonly used on Dodge Charger, Challenger, Dart, Coronet, Super Bee, Duster, Plymouth Road Runner, GTX, Barracuda, Belvedere, Satellite, and other classic Mopar vehicles.

The internally regulated design eliminates the need for an external voltage regulator while helping maintain consistent charging performance. Its one-wire capable configuration simplifies installation, making it a popular choice for hot rods, muscle cars, restoration projects, engine swaps, and custom Mopar builds where clean wiring and reliable operation are priorities.

Equipped with a 2-groove V-belt pulley and built using a Chrysler Square Back case design, this alternator is engineered for compatibility with many Chrysler charging system layouts from 1961-1989. The bright chrome finish adds a show-quality appearance while delivering the performance and reliability needed for long-term street use.

Whether you're replacing a factory alternator, upgrading a classic Mopar charging system, adding electric accessories, or building a high-performance street machine, this 100 amp alternator provides the charging performance, reliability, and electrical capacity needed to support today's vehicle demands.
