Overview

The Powermaster 58233 Alternator is a GM CS130D case style unit with an internal regulator. It provides 150 amps (Speedway Motors) or 165 amps (Truckstuff.com) at the top end and 100+ amps at idle. It features dual internal fans for high efficiency and maximum cooling, an offset left mount, a 6-groove serpentine pulley, and a PLFS voltage regulator. It is designed for OE hookup and is individually dyno-tested with a proof of performance guarantee. This black alternator is a high-output replacement for lower amp units and is made in the USA.
