High Output Alternator for Dodge Charger Durango (2011-2018) 5.7L

High-Output 300-Amp Alternator for 2011-2018 Dodge Charger,Durango (LD / WD)

What it Does: The 300-amp high-output alternator replaces the factory charging unit on 2011-2018 Charger and Durango models to eliminate voltage drop and deliver consistent, heavy-duty electrical output under maximum system loads.

The Stock Dodge Charger,Durango Charging System Limitations

Factory charging systems on the LD Charger and WD Durango max out between 160 and 220 amps. When running auxiliary equipment, aftermarket audio, or auxiliary lighting on the 5.7L HEMI V8, the factory alternator suffers severe voltage sag at idle. Sustained heavy draw causes excessive diode bridge heat soak, accelerating internal rectifier breakdown and overworking the powertrain control module's field control circuit.

The Engineering Solution

This heavy-duty 300-amp alternator features heavy-gauge copper hairpin stator windings and high-amperage press-fit avalanche rectifiers to maintain low internal operating temperatures under heavy duty cycles. Precision dynamically balanced rotors and premium sealed bearings ensure continuous output throughout the RPM band while preventing rotor slip under heavy acceleration. The direct-fit aluminum casing aligns with OEM bracket positions, directly replacing OEM part numbers 048018333AB, 48018333AB, 4804833AB, and 11575-300A.
