Designed for vehicles that need stronger charging capacity, this CS130 style alternator pairs 220 A charging output with a Serpentine, 6-groove, 2.610 in. outside diameter pulley configuration and chrome finish.

Charging Output & System Support
The 220 A amperage rating helps support electric fans, lighting, ignition components, fuel pumps, audio equipment, and additional electrical accessories. The 12 VDC rating keeps it aligned with common automotive charging-system requirements. The CS130 case family provides the charging-system layout used for compatible brackets, wiring, and mounting geometry. This makes it useful for street-driven builds, restorations, and upgraded accessory systems.

Pulley & Belt Alignment
The Serpentine, 6-groove, 2.610 in. outside diameter pulley setup is intended to match the selected accessory drive arrangement. Verify belt type, pulley offset, and bracket position before installation.

Case Construction & Cooling
The aluminum case uses a chrome finish with a 15.710 in. case circumference to balance durability, serviceability, and underhood presentation. The external fan design helps support heat management during accessory load and engine-bay operation. External fan included: Yes.

Installation & System Matching
Mounting details include split mount configuration with 6.610 in. between mounting feet and mounting configuration code 15. Regulator type: Internal. External regulator included: No. One-wire capable: Yes. Plug type: 4-pin. Terminal quantity: 5. Ground type: Case ground. Rotation direction: Clockwise. Verify charge-wire size, connector style, pulley alignment, bracket spacing, and engine-bay clearance before installation.
