Upgrade your vehicle's charging system with this GM CS130 Type 220 Amp Alternator engineered to deliver exceptional charging performance for vehicles with increased electrical demands. Designed for compatible GM CS130 charging system applications, this high-output alternator provides the charging capacity needed to support modern electrical accessories, performance upgrades, and demanding vehicle systems.

The 220 amp output provides significantly more charging capacity than many factory alternators and helps support dual electric cooling fans, electric fuel pumps, fuel injection conversions, upgraded ignition systems, aftermarket lighting, air conditioning systems, audio equipment, electric water pumps, air ride systems, and other high-demand electrical accessories. Increased charging capacity helps maintain stable system voltage during idle, cruising, and stop-and-go driving conditions while reducing voltage drops under heavy electrical loads.

Built using the proven GM CS130 alternator platform, this unit features an internal voltage regulator and one-wire capable operation for simplified installation. The CS130 design is commonly used on many GM applications and remains a popular charging system upgrade for street rods, muscle cars, classic trucks, restoration projects, and custom vehicle builds requiring increased charging performance.

Compatible with many Chevrolet Small Block, Chevrolet Big Block, GM V6, GM Inline 4, GM Inline 6, GM Diesel V8, and Oldsmobile V8 applications utilizing CS130 charging systems, this alternator is commonly used on Chevrolet Camaro, Chevelle, Nova, El Camino, Corvette, C/K Series trucks, and custom GM-based builds equipped with serpentine accessory drive systems. Fitment is based on alternator type, mounting configuration, wiring connections, bracket compatibility, and pulley alignment rather than engine size alone.

Equipped with a 6-groove serpentine pulley and finished in bright chrome, this alternator combines show-quality appearance with dependable charging capability. Whether you're replacing a factory CS130 alternator, upgrading a classic GM charging system, supporting EFI and electric fan conversions, or adding modern electrical accessories to your vehicle, this 220 amp alternator delivers the charging performance, reliability, and electrical capacity needed for today's demanding applications.
