Under prolonged idle and severe thermal soak within the tight \u003cstrong\u003e5.7L HEMI Eagle\u003c\/strong\u003e engine compartment, factory rectifiers overheat. This thermal stress degrades internal diodes, causing system voltage to sag below 12.8V, triggering erratic PCM sensor signals, premature battery fatigue, and ignition brownouts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis high-output unit steps up power delivery to an uncompromising 300 amps using dense, high-purity copper hairpin stator windings and heavy-duty avalanche diode rectifiers designed to thrive in extreme heat. The precision-balanced rotor prevents belt slip at high RPM, while upgraded dual internal cooling fans maximize cross-flow ventilation across the diodes. Direct bolt-in architecture allows seamless integration into factory mounts while directly replacing OEM units \u003cstrong\u003e048018333AB\u003c\/strong\u003e, \u003cstrong\u003e48018333AB\u003c\/strong\u003e, \u003cstrong\u003e4804833AB\u003c\/strong\u003e, and \u003cstrong\u003e11575-300A\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 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;\"\u003e2015-2018 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;\"\u003e5.7L HEMI Eagle \/ LA\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;\"\u003e375 hp \/ 410 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;\"\u003e048018333AB, 48018333AB, 4804833AB, 11575-300A\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\u003e2015-2018 Dodge Challenger R\/T 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2015-2018 Dodge Challenger R\/T Plus 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2015-2018 Dodge Challenger R\/T Shaker 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2017-2018 Dodge Challenger T\/A 5.7L 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 LA Challenger?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2018 Dodge Challenger equipped with the \u003cstrong\u003e5.7L HEMI Eagle\u003c\/strong\u003e engine. \u003cstrong\u003eDoes not fit 3.6L V6 Pentastar, 6.4L 392, or 6.2L Supercharged Hellcat engines due to differing bracket offsets and belt layouts.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade the primary charging wire?\u003c\/h4\u003e\n\u003cp\u003eYes, running a 1\/0 AWG Big-3 wiring upgrade from the alternator positive post to the battery and ground is strongly recommended to safely deliver full 300-amp current without thermal throttling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to sustain aggressive track abuse and extreme electrical demands, this charging setup guarantees steady voltage so your HEMI operates at maximum ignition power and throttle response at all times.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67566363738360,"sku":"DS-EE3PRK74Z","price":371.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-dodge-challenger-2015-2018-5-7l-1.jpg?v=1791087766","url":"https:\/\/performancechiptuning.com\/fr\/products\/high-output-alternator-for-dodge-challenger-2015-2018-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
