When subjected to aftermarket audio installations, auxiliary lighting, or commercial gear, the stock unit suffers from acute thermal saturation. Elevated engine bay temperatures in the transverse V6 layout cause factory diode pack breakdown, causing voltage decay below 12.6V at curb idle, excessive ripple current, and parasitic battery drain that accelerates lead-acid sulfation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eManufactured in the USA, this heavy-duty 250-amp alternator features precision copper hairpin stator windings and an upgraded avalanche diode rectifier bridge capable of enduring severe thermal load. The heavy-duty internal voltage regulator delivers consistent charging voltage (14.2V–14.8V) from idle through high RPM. Designed as a direct bolt-on for the High Value V6 platform, it interfaces seamlessly with OEM belt tensioners and OE bracketry while providing immediate relief from electrical strain.\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;\"\u003e2006-2011 Chevrolet Impala\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;\"\u003e3.5L (LZ4\/LZE), 3.9L (LZ8\/LZ9\/LGD) \/ \u003cstrong\u003eW-Body\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;\"\u003e211-242 hp \/ 214-242 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;\"\u003e\n\u003cstrong\u003e0124425032\u003c\/strong\u003e, \u003cstrong\u003eAL88007X\u003c\/strong\u003e, \u003cstrong\u003e10335497\u003c\/strong\u003e, \u003cstrong\u003e15594\u003c\/strong\u003e, \u003cstrong\u003e11185N\u003c\/strong\u003e, \u003cstrong\u003e11185R\u003c\/strong\u003e, \u003cstrong\u003e11185\u003c\/strong\u003e\n\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\u003e2006-2011 Chevrolet Impala 3.5L V6\u003c\/li\u003e\n  \u003cli\u003e2006-2011 Chevrolet Impala 3.9L 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 W-Body Impala?\u003c\/h4\u003e\n\u003cp\u003eYes, this unit directly fits the 2006-2011 Chevrolet Impala configured with the \u003cstrong\u003eLZ4\u003c\/strong\u003e 3.5L or \u003cstrong\u003eLZ9\u003c\/strong\u003e 3.9L V6 engines.\u003c\/p\u003e\n\n\u003ch4\u003eIs a wire upgrade required during installation?\u003c\/h4\u003e\n\u003cp\u003eDue to the increased 250A capacity, a 0-gauge or 4-gauge \"Big 3\" charging wire upgrade is strongly advised to avoid overheating factory charging harnesses.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained electrical loads without thermal throttling, this direct-fit alternator provides steady, ripple-free voltage to safeguard sensitive GM powertrain control modules and sustain auxiliary electronics.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67565712900344,"sku":"DS-EMBJHG6I1","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-chevrolet-impala-2006-2011-3-5l-3-9l-1.jpg?v=1791072122","url":"https:\/\/performancechiptuning.com\/fr\/products\/high-output-alternator-for-chevrolet-impala-2006-2011-3-5l-3-9l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
