When equipped with high-amperage commercial equipment—such as hydraulic pump power packs, auxiliary work lighting, heavy-duty winches, or aftermarket inverters—the OEM alternator suffers severe thermal saturation and voltage sag. Prolonged high-amp draw causes excessive heat soak in the stock thin-gauge stator windings, accelerating diode rectifier failure, triggering low-voltage battery dash warnings, dimming cab and headlamp illumination, and causing premature dual-battery bank degradation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 350-amp direct-replacement unit resolves electrical starvation by utilizing high-density, heavy-gauge pure copper stator windings combined with a precision dynamically balanced rotor. High-temp sealed dual bearings maintain shaft stability under extreme serpentine belt tension on the commercial front-end accessory drive (FEAD). A heavy-duty internal voltage regulator precisely stabilizes charging between 13.5V and 14.5V across all engine speeds, preventing transient voltage spikes. Engineered to retain the OEM 6-groove clutch pulley diameter, factory mounting footprints, and harness plug architecture, it drops directly in place without bracket modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 High Output 350-Amp 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;\"\u003e2011-2012 RAM 4500\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;\"\u003e6.7L Cummins ISB \/ D2 Chassis Cab\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;\"\u003e305 hp \/ 610 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;\"\u003e\n\u003cstrong\u003e04801768aa\u003c\/strong\u003e, \u003cstrong\u003e4801768AA\u003c\/strong\u003e, \u003cstrong\u003eA3TX0381\u003c\/strong\u003e, \u003cstrong\u003eA3TX0381ZC\u003c\/strong\u003e, \u003cstrong\u003e11443N\u003c\/strong\u003e, \u003cstrong\u003e11443R\u003c\/strong\u003e, \u003cstrong\u003e11443\u003c\/strong\u003e\n\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\u003e2011 RAM 4500 Cab \u0026amp; Chassis 6.7L Turbo Diesel\u003c\/li\u003e\n  \u003cli\u003e2012 RAM 4500 Cab \u0026amp; Chassis 6.7L Turbo Diesel\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 D2 4500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2012 RAM 4500 equipped with the \u003cstrong\u003e6.7L Cummins ISB\u003c\/strong\u003e turbo diesel engine.\u003c\/p\u003e\n\n\u003ch4\u003eShould I upgrade my wiring when installing this 350-amp unit?\u003c\/h4\u003e\n\u003cp\u003eFor maximum charging efficiency and safe current transfer, upgrading the main B+ charging lead and chassis ground straps with a 0-gauge or 1\/0 \"Big 3\" wiring kit is highly recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe RAM Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the abusive operating cycles of commercial hauling and towing platforms, this heavy-duty unit supplies stable, high-amperage current under extreme underhood heat loads to protect critical onboard electronics and keep commercial auxiliary rigs running reliably.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898993869048,"sku":"DS-EHSVZUEET","price":705.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-ram-4500-2011-2012-6-7l-1.jpg?v=1793330338","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-ram-4500-2011-2012-6-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
