Alternator- GM AD230 165 Amp w/6-Groove Pulley

The GM AD230 165 Amp Alternator with 6-Groove Pulley from POWERMASTER is the go-to upgrade for builders and mechanics seeking reliable electrical output in high-demand engine builds. Whether you're running a stroker, turbocharged platform, or adding significant auxiliary loads—electric fans, upgraded ignition systems, or modern audio components—this alternator delivers the sustained amperage your vehicle demands. The AD230 case design is compact enough to fit tight engine bays while offering superior charging capacity compared to factory units, making it ideal for both street performance and demanding off-road applications.

POWERMASTER engineered this unit with internal voltage regulation and a robust 6-groove serpentine pulley that ensures efficient belt drive engagement and minimal slippage under load. The 165-amp output rating provides ample headroom for sustained charging cycles without voltage sag, critical when running aggressive fuel injection, engine management systems, or high-output lighting. At 13.02 lbs with compact dimensions (8.05 x 7.6 x 9.55 inches), the alternator balances manufacturing quality with practical installation constraints, reducing parasitic drag while maintaining thermal stability during extended highway cruising or full-throttle track sessions.

This alternator is engineered for GM platforms, making it a direct fit for Gen I and Gen II small-block Chevrolet engines, LS variants, and other GM applications where the AD230 case footprint is OEM or commonly adapted. Installation typically requires standard serpentine belt routing, and the 6-groove pulley accommodates both traditional and modern accessory drive configurations. Builders appreciate the POWERMASTER reputation for durability and consistent output—this unit won't leave you stranded on the highway or at the drag strip when electrical demand spikes during acceleration or sustained high-RPM operation.
