Under thermal stress and engine-bay heat soak, internal resistance increases, causing significant amperage drop at idle. When running auxiliary electrical loads—such as aftermarket fuel systems, high-draw radiator fans, standalone ignition coils, or high-wattage audio amplifiers—the OEM unit cannot maintain system voltage. This causes voltage sag below 12.8V, inducing ignition coil starvation, erratic sensor telemetry, and accelerated battery drain.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eManufactured in the USA, this heavy-duty 300-amp alternator utilizes precision copper windings and heavy-gauge internal rectifiers to supply sustained current across the entire RPM range. Featuring high-temp avalanche diodes and enhanced internal heat dissipation, it resists thermal degradation and maintains a solid 14.4V to 14.8V charging threshold under peak accessory loads. Designed as a direct bolt-in unit, it directly interchanges with factory hardware and OEM numbers including \u003cstrong\u003e4896805AD\u003c\/strong\u003e, \u003cstrong\u003e421000-0620\u003c\/strong\u003e, and \u003cstrong\u003e11383\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 300 Amp High Output Alternator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2009-2010 Dodge Challenger\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e3.5L V6, 5.7L HEMI, 6.1L HEMI \/ LC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e250 hp - 425 hp \/ 250 lb-ft - 420 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e11383, 4896805AD, 421000-0620, 210-0653, 11383N, 11383R, 11383-300A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2010 Dodge Challenger 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2009-2010 Dodge Challenger 5.7L HEMI V8\u003c\/li\u003e\n  \u003cli\u003e2009-2010 Dodge Challenger 6.1L SRT8 HEMI V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the LC Challenger?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2010 Dodge Challenger equipped with the \u003cstrong\u003e3.5L V6\u003c\/strong\u003e, \u003cstrong\u003e5.7L HEMI\u003c\/strong\u003e, or \u003cstrong\u003e6.1L HEMI\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my main power cabling when installing this alternator?\u003c\/h4\u003e\n\u003cp\u003eYes, running a 1\/0 AWG \"Big Three\" power wire upgrade with an inline 300A fuse is strongly recommended to safely deliver full current to the battery without melting stock harness wiring.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eModern Mopar muscle requires unrelenting electrical current to keep fuel pumps primed and ignition sparks sharp at high engine speeds.
