The included 3/8-inch V-belt pulley is designed for use with compatible V-belt drive systems commonly found on street rods, hot rods, classic vehicles, and custom engine combinations. The one-wire capable design simplifies wiring while the internal voltage regulator helps maintain consistent charging performance without the need for an external regulator.

Finished in bright chrome, this alternator delivers both show-quality appearance and dependable charging capability. Whether you're building a street rod, upgrading a hot rod, completing an engine swap, or solving clearance issues in a custom engine bay, this Denso-style mini alternator provides the compact packaging, charging performance, and reliability needed for dependable operation.
