Under modern trail demands—including recovery winches, auxiliary LED light bars, high-displacement audio setups, or dual electric cooling fans—the OEM stator and internal diodes suffer severe thermal overload. Extended current draw at low engine RPM causes immediate system voltage sag, leading to battery depletion, erratic ECM sensor readings, and premature rectifier failure due to heat saturation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver a sustained 200-amp capacity, this heavy-duty unit resolves idle and peak-draw deficits across the entire rev band. Built around precision, high-density copper hair-pin stator windings and high-temperature avalanche diode packs, it withstands extreme underhood engine-bay heat without degrading output voltage. A balanced rotor assembly minimizes vibration wear, while the precision-machined housing mounts directly to factory brackets without bracket modification or belt alignment shimming, maintaining full compatibility with the factory serpentine belt geometry and powertrain control module (PCM) field regulation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Alternator (200 Amp)\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;\"\u003e2001-2004 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;\"\u003e4.7L PowerTech V8 \/ WJ\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;\"\u003e235 hp \/ 295 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;\"\u003eAL6541X, 210-0515, 56041693AA, 13873, 121000-4440, 13873N, 13873-200\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\u003e2001-2004 Jeep Grand Cherokee 4.7L V8 (WJ Chassis)\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 WJ Grand Cherokee?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2001-2004 Jeep Grand Cherokee equipped with the \u003cstrong\u003e4.7L PowerTech V8\u003c\/strong\u003e engine.
