Alternator GM CS121 100 Amp 16 Volt Black

The Alternator GM CS121 100 Amp 16 Volt Black by POWERMASTER is a high-output race alternator designed for performance vehicles that require reliable electrical generation at elevated RPMs. This unit is built to replace OEM General Motors alternators and is suitable for engine swaps and dedicated race platforms where stock charging capacity is insufficient.

Featuring a durable aluminum case with a black powder coat finish, this alternator provides corrosion resistance and a professional appearance. The 1-wire configuration simplifies wiring and installation, while the unit ships without a pulley, allowing builders to select the appropriate pulley ratio for their specific engine combination. The rear-post battery connection ensures secure terminal attachment.
