Product Overview
The 4801779AI is a Chrysler Mopar-spec replacement alternator delivering 12V output with a 6-rib (6PK) pulley, engineered for Chrysler vehicles that use the 180A / 220A high-output alternator family. This aftermarket unit matches the original charging-system specification of these platforms.
Fitted with internal regulator design, this brand-new alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 180A / 220A rating is factory-correct for the heavy electrical load of large Chrysler cars, supporting climate control, heated and powered accessories, premium infotainment and factory electrical equipment.
Key physical specs: net weight 7.35 kg, gross weight 7.75 kg, overall dimensions 240 x 120 x 160 mm, supplied inside neutral kraft inner carton.
The Chrysler Platform and 180A / 220A High-Output Charging System
Large Chrysler sedans and crossovers carry a substantial factory electrical load, which is why the charging system is rated at 180A or 220A rather than a lower output. The 6-rib pulley matches the original accessory-belt layout, driving alternator, water pump and power-steering pump.
This high-output unit is specified as 12V 180A / 220A, matching the factory charging-system specification of these platforms. Installing a pulley with the wrong rib count will cause belt mis-tracking, slippage, premature belt wear and charging faults. Always cross-check the amperage label and OE number against your old alternator before ordering.

Engine Compatibility and Cross Reference
This alternator fits Chrysler vehicles that use the 12V 180A / 220A 6PK alternator family. Do not rely solely on brand name for fitment validation; always verify the specific model, engine code, old-part OE number, pulley rib-count and amp label on your original alternator.
| Vehicle | Engine Code | Notes |
|---|---|---|
| Chrysler models | Verify model and engine code | Verify 6PK, amperage label and mounting layout |
Multiple Mopar and supplier OE numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, 4801779AI serves as a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the amperage label on your old alternator: confirm whether it is 180A or 220A. Different amp ratings are not interchangeable.
2. Count pulley ribs: this unit requires 6PK (6-rib). Units with a different rib count are incompatible for this accessory drive setup.
3. Confirm the exact Chrysler model, engine code and production year of your vehicle.
4. Match against OE / reference part numbers stamped on your original housing.
5. Weight cross-check: genuine matching unit weighs approximately 7.35 kg net; significant weight difference indicates wrong assembly.
Application Scenarios
Independent repair shops and Chrysler-Dodge specialists servicing large Chrysler sedans and crossovers across North America, Middle East, Europe and Asia-Pacific markets.
Parts counters and jobbers stocking American-brand replacement electrical components.
Vehicle owners restoring and maintaining original-spec Chrysler models.
Used-car export traders supplying pre-owned Chrysler vehicles to global secondary markets.
Owners with heavy electrical accessories who require a factory-spec high-output charging system.
FAQ
Q: Which Chrysler models does this alternator fit?
A: It fits Chrysler vehicles that use the 12V 180A / 220A 6PK alternator family. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.
Q: Is this alternator new?
A: Yes, this is a brand-new high-output unit with a 1-year warranty and 10-day dispatch lead-time.
Q: The sheet lists 180A and 220A, which amperage is correct for my car?
A: Confirm the amperage label on your original alternator and match it before ordering, since different amp ratings are not interchangeable.
Q: My old alternator shows OE number 4801779AH or RL801779AG, will 4801779AI work?
A: Yes. These numbers belong to the same alternator family, differing only by production revision and market specification. It serves as a direct replacement.
Q: What is the normal charging voltage after installation?
A: With the engine running, output voltage should read 14.0V-14.7V. If it is lower than 13.8V or higher than 15V, check wiring or belt tension.
Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, wrong belt tension, or vehicle-wiring faults.
In Practice
For technicians working on Chrysler platforms: Before removing the existing alternator, perform charging-system diagnostics. Measure battery terminal running voltage with a multimeter. Weak batteries, corroded ground connections or a faulty main harness can mimic alternator failure symptoms. Always disconnect the battery negative terminal before commencing removal work.
Take photos of wiring connectors and bolt positions during disassembly to avoid mis-routing during reassembly. Observe correct belt tension: 10-15 mm deflection when pressing the belt mid-span. Over-tightened belts accelerate alternator bearing wear; loose tension creates slipping and insufficient charging. Torque mounting bolts to FCA workshop-manual specifications.
On vehicles equipped with an intelligent charging system, use an OBD scanner to perform generator initialization and BMS calibration after installation where required, so the system can correctly recognise charging status. Inexperienced home mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop. Incorrect wiring risks burning the alternator or vehicle-system components.
