When retrofitting recovery winches, electric auxiliary fans, high-intensity LED light bars, or onboard air systems, factory charging capacity collapses immediately. At trail crawl speeds and idle, the stock stator cannot provide sufficient amperage, draining the primary battery, causing deep voltage sag, and subjecting the OEM diode bridge to severe thermal fatigue and eventual electrical burnout.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty 250-amp unit is engineered specifically for extreme trail and utility duty. Featuring precision hair-pin stator windings, precision-balanced rotor assemblies, and a heavy-duty avalanche diode rectifier, this charging unit produces substantial amperage at low engine RPMs while shedding heat under prolonged heavy load. Manufactured in the USA inside an exact OEM-dimensioned casing, it mounts directly to factory bracket locations without requiring mechanical modification, while delivering stable voltage regulation directly to the vehicle wiring harness.\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;\"\u003e1999-2000 Jeep 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;\"\u003e2.5L AMC I4, 4.0L PowerTech I6 \/ XJ\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;\"\u003e125 hp \/ 150 lb-ft (2.5L) | 190 hp \/ 225 lb-ft (4.0L)\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;\"\u003e56005685AC, 210-0471, 13822, 13822N, 121000-3620, 138221, 13822-250A\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\u003e1999-2000 Jeep Cherokee 2.5L Inline-4\u003c\/li\u003e\n  \u003cli\u003e1999-2000 Jeep Cherokee 4.0L Inline-6\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 XJ Cherokee?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-in fit for the 1999-2000 Jeep Cherokee equipped with the \u003cstrong\u003e2.5L Inline-4\u003c\/strong\u003e or \u003cstrong\u003e4.0L Inline-6\u003c\/strong\u003e engine utilizing OEM factory mounting brackets.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my charging cables when installing this 250-amp alternator?\u003c\/h4\u003e\n\u003cp\u003eYes, a heavy-gauge \"Big 3\" wiring upgrade (minimum 4 AWG or 0\/1 AWG charging cable and matching ground straps) is required to safely carry the increased current load and prevent resistance-induced wire harness melting.\u003c\/p\u003e\n\n\u003ch3\u003eThe Jeep Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle harsh off-camber rock crawling, continuous winching loads, and punishing back-country overland expeditions, this high-amperage alternator provides the robust reserve capacity needed to ensure your vehicle starts, charges, and runs reliably in any off-grid environment.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67565756317944,"sku":"DS-E2N0261M3","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-jeep-cherokee-1999-2000-2-5l-4-0l-1.jpg?v=1791073904","url":"https:\/\/performancechiptuning.com\/de\/products\/high-output-alternator-for-jeep-cherokee-1999-2000-2-5l-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
