Under sustained electrical demand, factory rectifiers quickly heat soak. This leads to diode thermal breakdown, stator insulation fatigue, and severe idle voltage drop below 12.8V, which stresses sensitive CAN-bus electronics and drains the primary battery reserve.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eManufactured in the USA, this 350-amp high-output replacement utilizes high-temperature hairpin windings and a heavy-duty avalanche diode rectifier bridge to optimize thermal dissipation and current transfer. Designed to integrate directly with factory mounting points, it delivers reliable output across the operating RPM band of the \u003cstrong\u003e3.6L Pentastar\u003c\/strong\u003e engine. Precision-balanced internal rotors and premium bearings reduce parasitic drag and resist mechanical vibration during extreme off-road articulation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 350-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;\"\u003e2011-2015 Jeep Grand Cherokee\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;\"\u003e3.6L Pentastar V6 \/ WK2\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;\"\u003e290 hp \/ 260 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;\"\u003e04801779AG, 4801779AG, 4801779AH, 4801779AL, P04801779AG, RL801779AG, 421000-0750, 421000-0751, 21000-0752, TN421000-0750, 11572N, 11572, 11572-350A\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\u003e2011-2015 Jeep Grand Cherokee (Laredo, Limited, Overland, Summit) 3.6L V6\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 WK2 Grand Cherokee?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-in fit for the 2011-2015 Jeep Grand Cherokee equipped with the \u003cstrong\u003e3.6L Pentastar\u003c\/strong\u003e engine; it does not fit 5.7L Hemi, 6.4L SRT, or 3.0L EcoDiesel models.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my charging cables for a 350-amp alternator?\u003c\/h4\u003e\n\u003cp\u003eYes, executing a \"Big 3\" electrical upgrade using 1\/0 AWG power and ground cabling is required to safely transfer 350 amps and avoid thermal resistance in the stock harness.\u003c\/p\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand remote trail expeditions, heavy recovery operations, and sustained accessory load, this charging upgrade provides the relentless electrical stability necessary for demanding overland and towing applications.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67565797376248,"sku":"DS-EY61WNP3E","price":350.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-jeep-grand-cherokee-2011-2015-3-6l-1.jpg?v=1791075132","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-jeep-grand-cherokee-2011-2015-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
