When modern trail builds incorporate dual battery isolators, high-draw recovery winches, onboard air compressors, 12V overland refrigeration, and auxiliary lighting arrays, the stock rectifier overheats. This persistent overload causes severe voltage sag below 12.5V, excessive thermal degradation of stator windings, depleted battery banks, and ECU current-starvation during low-RPM crawling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered and manufactured in the USA, this direct-replacement 250-amp alternator features heavy-duty hairpin windings, high-temperature insulating resins, and an upgraded heavy-duty diode bridge. By utilizing an optimized rotor and heavy-gauge copper internals, it delivers substantial idle current while dissipating heat far more efficiently than the OEM Denso casing. It directly swaps with OEM hardware using factory belt routing to provide clean, ripple-free direct current.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 250-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;\"\u003e2010-2013 Toyota 4Runner\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;\"\u003e\n\u003cstrong\u003e1GR-FE\u003c\/strong\u003e (4.0L Dual VVT-i) \/ \u003cstrong\u003eN280\u003c\/strong\u003e\n\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;\"\u003e270 hp \/ 278 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\u003cstrong\u003e104210-284, 104210-2840, 11517, 11517-250A\u003c\/strong\u003e\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\u003e2010 Toyota 4Runner 4.0L V6 (SR5, Trail, Limited)\u003c\/li\u003e\n  \u003cli\u003e2011 Toyota 4Runner 4.0L V6 (SR5, Trail, Limited)\u003c\/li\u003e\n  \u003cli\u003e2012 Toyota 4Runner 4.0L V6 (SR5, Trail, Limited)\u003c\/li\u003e\n  \u003cli\u003e2013 Toyota 4Runner 4.0L V6 (SR5, Trail, Limited)\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 N280 4Runner?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-in fit for the 2010-2013 Toyota 4Runner equipped with the \u003cstrong\u003e1GR-FE\u003c\/strong\u003e 4.0L V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my charging cables for a 250-amp alternator?\u003c\/h4\u003e\n\u003cp\u003eA \"Big 3\" wiring upgrade utilizing 0-gauge or 1\/0-gauge cable is strongly recommended to safely flow 250 amps from the alternator terminal to the battery without resistive voltage drop.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Overland Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned for severe-duty off-road and towing conditions, this unit ensures your overland electrical architecture maintains stable operating voltage under peak winching and accessories loads in extreme remote environments.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67565811171576,"sku":"DS-E7H2P3FMM","price":249.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-toyota-4runner-2010-2013-4-0l-1.jpg?v=1791075471","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-toyota-4runner-2010-2013-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
