Alternator 140 Amp 1 Wire CS130 GM Style

The Alternator 140 Amp 1 Wire CS130 GM Style by POWERMASTER is a high-output charging solution engineered for classic and late-model GM vehicles requiring reliable electrical power generation. This alternator is designed for enthusiasts and restoration professionals who demand dependable charging performance in street rods, vintage trucks, and performance builds. The single-wire configuration simplifies installation by reducing wiring complexity while delivering consistent 140-amp output to support modern electrical accessories and engine demands.

Built with an aluminum case construction and chrome finish, the CS130 alternator features a left-offset mounting design and accommodates single V-belt pulley systems common to GM applications. The 140-amp capacity ensures sufficient power for fuel injection systems, electric cooling fans, ignition upgrades, and auxiliary lighting without voltage sag during idle or heavy electrical load conditions. The 1-wire/3-wire configuration option provides flexibility for both traditional and modern wiring schemes, making this alternator compatible with vehicles spanning multiple generations of GM platform design.

This unit is ideal for Chevrolet, GMC, and Buick owners upgrading charging systems in street machines, daily drivers, and off-road builds where stock alternators fall short. Installation requires proper belt tension adjustment and secure mounting to the engine block using existing GM attachment points. The compact 7.6 x 7.4 x 9.4-inch footprint and 11.75-pound weight ensure straightforward fitment in tight engine bays, while the chrome finish complements both show-quality restorations and functional builds. Verify your vehicle's mounting configuration and pulley compatibility before purchase to ensure optimal fitment and performance.
