High Output Alternator for Chrysler 300 (2005-2006) 3.5L 5.7L 6.1L

High-Amp 250A Direct-Fit Alternator for 2005-2006 Chrysler 300 (LX)

What it Does: The 250-Amp High Output Alternator replaces the factory low-amperage charging unit on the 2005-2006 Chrysler 300 to maintain constant 14.4-volt system stability under heavy auxiliary electrical draw.

The Stock Chrysler 300 Charging System Shortcoming

Factory LX platform Chrysler 300 sedans equipped with the 3.5L V6 (EGG), 5.7L HEMI (EZB), or 6.1L SRT HEMI (ESF) utilize stock 140A or 160A alternators. When loaded with aftermarket sound systems, secondary electric cooling fans, or air suspension compressors, the factory stator windings suffer severe heat soak. This leads to idle voltage drop below 12.8V, premature bridge rectifier diode failure, and drained batteries due to insufficient amperage output at low RPM.

The Engineering Solution

Manufactured in the USA, this heavy-duty 250-amp alternator features high-temperature copper hairpin stator windings and an oversized avalanche diode rectifier to resist thermal breakdown. It delivers massive current gains across the entire powerband while maintaining a factory mounting footprint, providing a clean bolt-on solution for OEM units like 4896805AA and 421000-0261 without bracket modification.

Frequently Asked Questions & Fitment Warnings

Does this fit the LX 300?

Yes, this is a direct bolt-in fit for the 2005-2006 Chrysler 300 equipped with the 3.5L, 5.7L, or 6.1L engine options.

Do I need to upgrade the primary charging wiring?

Installing a 1/0 AWG "Big 3" battery ground and alternator power lead upgrade is strongly advised to support 250-amp flow without thermal resistance loss.
