The stock low-amperage stator generates excessive heat under load, inducing diode pack degradation, rotor resistance, and voltage sag below 13.0V at idle speeds. Over time, persistent thermal strain degrades charging efficiency, causing recurring battery failure and erratic accessory operation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis upgraded unit solves capacity deficits by utilizing heavy-gauge, high-temperature copper stator windings and a precision-balanced rotor to yield sustained 250-amp delivery. High-grade internal voltage regulation maintains a stable 13.8V to 14.5V output to prevent component starvation across all RPM bands. Assembled with premium sealed bearings and direct-fit OE casing architecture, it bolts into place using the factory serpentine belt alignment and plugs into the OEM engine harness without modifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x High-Output 250A Alternator (Part # 11433-250A)\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 Ford Explorer\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;\"\u003e4.6L 3-Valve Modular V8 \/ U251\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;\"\u003e292 hp \/ 315 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;\"\u003e104210-5850, GL-962, 9L2Z-10346-A, 11433, 11433N\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 Ford Explorer Eddie Bauer 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2009-2010 Ford Explorer Limited 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2009-2010 Ford Explorer XLT 4.6L 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 U251 Explorer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2010 Ford Explorer equipped with the \u003cstrong\u003e4.6L 3-Valve Modular V8\u003c\/strong\u003e engine.
