When powering auxiliary lighting, winches, onboard air, or high-draw audio setups, the OEM rotor and stator assembly suffers from severe thermal saturation. In the cramped engine bay of the \u003cstrong\u003ePowerTech 3.7L\u003c\/strong\u003e V6, high operating temperatures degrade diode bridge rectifiers, causing voltage drop, battery discharge at idle, and erratic sensor references across the vehicle's multiplexed bus.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for sustained heavy duty cycles, this 250-amp unit features precision hairpin or high-density stator windings coupled with heavy-duty avalanche diodes to combat thermal breakdown. The housing provides improved thermal dissipation over OE cast units, maintaining high charging voltage even at low idle RPM. It installs into the factory accessory bracket location and directly interchanges with OEM part numbers such as \u003cstrong\u003e56029914AA\u003c\/strong\u003e, \u003cstrong\u003e04801252AA\u003c\/strong\u003e, and \u003cstrong\u003e13913\u003c\/strong\u003e without bracket modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 High Output 250 Amp 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;\"\u003e2002-2006 Jeep Liberty\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;\"\u003e3.7L PowerTech V6 \/ KJ\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;\"\u003e210 hp \/ 235 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;\"\u003e334-1508, 04801252AA, 4801252AA, 5170748AA, 210-0484, 42100-0043, 421000-0311, 56029914AA, 13913, 421000-0040, 421000-0042, 13913N, 13913R, 13913-250A\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\u003e2002-2006 Jeep Liberty Sport 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2002-2006 Jeep Liberty Limited 3.7L V6\u003c\/li\u003e\n  \u003cli\u003e2002-2006 Jeep Liberty Renegade 3.7L V6\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 KJ Liberty?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2006 Jeep Liberty equipped with the \u003cstrong\u003ePowerTech 3.7L\u003c\/strong\u003e engine.
