Operating recovery winches, off-road lighting, communication gear, or auxiliary audio setups quickly overtaxes the stock charging circuit. Under sustained current draw, factory rectifier diodes suffer from severe heat soak, causing idle voltage to collapse below 12.6V, starving ignition systems, degrading AGM batteries, and eventually burning out the stock stator windings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis Made in USA 140-amp direct-replacement alternator doubles factory output to supply steady current across the entire RPM band. Built in a precision-cast direct-fit casing, it features high-temperature copper windings, low-resistance avalanche diodes, and an upgraded heavy-duty internal voltage regulator. The unit maintains clean 14.4V charging profiles under load, preventing voltage drop at curb idle without requiring custom bracketry or belt drive alterations.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 140-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: solid font-size: min-width:\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;\"\u003e2000-2004 Nissan Xterra\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\u003eKA24DE\u003c\/strong\u003e \/ \u003cstrong\u003eWD22\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;\"\u003e143 hp \/ 154 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;\"\u003eAL2377X, 210-31556, LR170-766, LR170-766B, 23100-9Z000, 13778N, 13778R, 13778\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\u003e2000-2004 Nissan Xterra XE 2.4L L4 (Gasoline)\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 WD22 Xterra?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2000-2004 Nissan Xterra equipped with the \u003cstrong\u003eKA24DE\u003c\/strong\u003e 2.4L engine. \u003cstrong\u003eThis alternator will not fit 3.3L V6 models (VG33E or supercharged VG33ER).\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my charging lead wiring?\u003c\/h4\u003e\n\u003cp\u003eUpgrading the primary alternator-to-battery B+ cable to a 4-gauge lead with an inline fuse (Big 3 upgrade) is strongly advised to safely transfer the full 140-amp current without thermal resistance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Off-Road Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for rigorous backcountry exploration, this unit delivers the robust charging overhead required to sustain severe winch pulls and prolonged trail run demands without risk of battery strandings.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67566249574648,"sku":"DS-E7OSJ4WAC","price":236.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-nissan-xterra-2000-2004-2-4l-1.jpg?v=1791085292","url":"https:\/\/performancechiptuning.com\/es\/products\/high-output-alternator-for-nissan-xterra-2000-2004-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
