GM CS130 160 AMP Alter- nator Chrome Finish

The PROFORM GM CS130 160 AMP Alternator with chrome finish is a high-output charging system designed for GM applications requiring reliable electrical generation in street and performance driving scenarios. This CS130-type alternator delivers 160 amps at 12 volts, providing the electrical capacity needed for modern engine management systems, fuel injection, ignition control, and auxiliary accessories without voltage sag under sustained demand.

Built with an aluminum case and featuring a single V-belt pulley configuration, the CS130 160 amp alternator uses a straight-mount design compatible with standard GM engine blocks. The 1-wire installation simplifies electrical integration compared to multi-terminal designs, reducing wiring complexity during engine swap or restoration work. Chrome plating protects the aluminum housing against oxidation and corrosion, maintaining appearance in engine bays exposed to moisture and salt air. At 11.72 pounds, the compact 7.45 × 6.75 × 7.9-inch form factor fits within tight engine compartment constraints common to vintage and modern GM platforms.

This 160-amp output unit serves hot rod builders, engine rebuild specialists, and performance enthusiasts whose upgraded fuel systems, ignition systems, or auxiliary electronics demand higher charging capacity than original equipment alternators can supply. The CS130 platform is widely adopted in GM restoration and custom builds where electrical reliability and visual presentation matter equally. Buyers should verify pulley diameter and mounting bolt pattern against their specific engine block configuration before purchase.

PROFORM specializes in engine performance and restoration components, and the CS130 alternator represents a core upgrade choice for builders seeking modern charging performance with period-correct or custom appearance. The chrome finish option appeals to show-quality builds where engine bay aesthetics are part of the final product.
