Maximize charging performance while saving valuable engine bay space with this Denso-Style 90 Amp Mini Race Alternator featuring a serpentine pulley. Designed for street rods, hot rods, race cars, drag cars, engine swaps, kit cars, and custom builds, this compact alternator delivers dependable charging performance in a lightweight, space-saving package.
The 90 amp output provides the charging capacity needed to support upgraded ignition systems, electric fuel pumps, electric cooling fans, auxiliary lighting, gauges, data logging systems, and other electrical accessories commonly found on performance vehicles. Increased charging capacity helps maintain stable system voltage while supporting modern electrical demands during street and competition use.
Built with a compact Denso-style housing, this mini alternator is engineered for applications where clearance is limited around headers, steering components, suspension systems, chassis tubing, and other engine bay obstacles. Its lightweight construction and reduced overall dimensions make it a popular choice for engine swaps, custom chassis builds, race vehicles, and performance applications where traditional alternators may not fit.
The included serpentine pulley is designed for use with compatible serpentine belt drive systems commonly found on modern engine combinations and custom accessory drive setups. The one-wire capable design simplifies wiring while the internal voltage regulator helps maintain consistent charging performance without requiring an external regulator.
Finished in bright chrome, this alternator combines show-quality appearance with dependable charging capability. Whether you're building a street rod, upgrading a hot rod, completing an LS swap, finishing a race car, or solving clearance issues in a custom engine bay, this Denso-style mini alternator delivers the compact packaging, charging performance, and reliability needed for dependable operation.
