Designed for vehicles running large audio systems, auxiliary  electronics, winches, lighting, and other high-draw accessories, it  delivers stable voltage under load where factory charging systems  fall short.\u003c\/p\u003e\n\u003cp\u003eBuilt  in the USA using premium components, this alternator is designed for  continuous high-amperage output with reliability as the priority.  Strong idle output and a broad usable RPM range help maintain voltage  stability during real-world driving conditions, not just at peak  engine speeds. Each unit is hand-assembled and tested to ensure  consistent performance and long service life.\u003c\/p\u003e\n\u003cp\u003eLike  most high-output alternators, this unit is equipped with a smaller  overdrive pulley to help maintain maximum output at idle and will  typically require a belt that is 1\/2 inch to 1 inch shorter than the  factory belt to achieve proper belt tension.\u003c\/p\u003e\n\u003cp\u003eTo  simplify installation, the alternator includes a dedicated adapter  plug. One side connects directly to the alternator, while the  opposite side plugs into the factory vehicle harness, allowing for a  clean, plug-and-play electrical connection without modification to  the OEM wiring.\u003c\/p\u003e\n\u003cp\u003eFeatures  include:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n  400  \tamps of peak output for extreme electrical demand  \n  \u003c\/li\u003e\n\u003cli\u003eStrong  \tidle output and improved voltage stability under load\n  \u003c\/li\u003e\n\u003cli\u003eOverdrive  \tpulley included to enhance low-RPM performance  \n  \u003c\/li\u003e\n\u003cli\u003ePlug-and-play  \tadapter harness included for direct factory connection  \n  \u003c\/li\u003e\n\u003cli\u003eHeavy-duty  \tinternal components designed for sustained high-current operation  \n  \u003c\/li\u003e\n\u003cli\u003eDirect-fit  \tdesign for select Nissan applications  \n  \u003c\/li\u003e\n\u003cli\u003eIdeal  \tfor high-power audio systems, off-road accessories, lighting, and  \tauxiliary power needs  \n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor  Nissan owners pushing serious electrical loads, this Mechman 400-amp  alternator delivers dependable, high-output charging performance  built for both daily use and demanding environments.\u003c\/p\u003e\n\n\u003ch2\u003eFitment Table | B11119400M – Plug Code: 325\u003c\/h2\u003e\n\u003ctable class=\"table-bootstrap\"\u003e\n  \u003ctbody\u003e\n    \u003cthead class=\"thead-dark-bootstrap\"\u003e\n\t\t\u003ctr\u003e\n      \u003cth\u003eMake \/ Model\u003c\/th\u003e\n      \u003cth\u003eYear\u003c\/th\u003e\n      \u003cth\u003eEngine Size\u003c\/th\u003e\n    \u003c\/tr\u003e\n\t\t\u003c\/thead\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInfiniti Q50\u003c\/td\u003e\n      \u003ctd\u003e2016-2023\u003c\/td\u003e\n      \u003ctd\u003e3.0L V6\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInfiniti Q60\u003c\/td\u003e\n      \u003ctd\u003e2017-2021\u003c\/td\u003e\n      \u003ctd\u003e3.0L V6\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNissan Frontier\u003c\/td\u003e\n      \u003ctd\u003e2005-2019\u003c\/td\u003e\n      \u003ctd\u003e2.5L L4\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNissan X-Trail\u003c\/td\u003e\n      \u003ctd\u003e2008\u003c\/td\u003e\n      \u003ctd\u003e2.5L L4\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNissan Z\u003c\/td\u003e\n      \u003ctd\u003e2023-2025\u003c\/td\u003e\n      \u003ctd\u003e3.0L V6\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSuzuki Equator\u003c\/td\u003e\n      \u003ctd\u003e2009-2012\u003c\/td\u003e\n      \u003ctd\u003e2.5L L4\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eInstallation  Notes:\u003c\/p\u003e\n\u003cp\u003eThis  unit comes equipped with a smaller 1.75-inch diameter alternator  pulley and will require a slightly shorter drive belt for proper belt  tension.  Not recommended for sustained use above 5,000 RPM  engine speed. \u003cstrong\u003eIf a  larger pulley is required\u003c\/strong\u003e,  please reach out to Mechman’s support team and we can work to get  you an underdrive pulley to meet your RPM demands. \u003c\/p\u003e\n\n","brand":"Mechman","offers":[{"title":"Default Title","offer_id":52958145904751,"sku":"B1119400M","price":649.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/0519\/9727\/files\/B11256XXXM-001_829a9518-87b4-4012-b36c-265e1711422a.png?v=1776275967","url":"https:\/\/caraudiobargain.com\/products\/mechman-400-amp-machined-billet-alternator-for-nissan-infiniti-2-5l-3-0l-b1119400m","provider":"Car Audio Bargain","version":"1.0","type":"link"}
