{"product_id":"400-amp-alternator","title":"400-Amp Alternator","description":"The Mechman 400-amp high-output alternator is engineered to deliver critical, consistent, high-current power for demanding Nissan applications. It is ideal for vehicles equipped with large audio systems, extensive auxiliary electronics, winches, lighting, or other accessories that place a significant draw on the electrical system, providing stable voltage under load where factory systems often fall short.\n\nBuilt in the USA using premium components, this alternator prioritizes reliability for continuous high-amperage output. It features strong idle output and a broad usable RPM range to maintain voltage stability during real-world driving conditions. Each unit is meticulously hand-assembled and tested to ensure consistent performance and a long service life.\n\nInstallation is simplified with a dedicated adapter plug that connects directly to the alternator and the factory vehicle harness, offering a clean, plug-and-play electrical connection without requiring modifications to the OEM wiring. The alternator includes a smaller overdrive pulley (1.75-inch diameter) to maximize output at idle, which typically necessitates a drive belt 1\/2 to 1 inch shorter than the factory belt for proper tension. It is not recommended for sustained use above 5,000 RPM engine speed. For those requiring a larger pulley, Mechman support can provide an underdrive pulley option.\n\nThis alternator is a direct-fit design for select Nissan applications, specifically the Infiniti FX35 (2003-2008), Infiniti G35 (2003-2006), Infiniti QX4 (2003), Nissan 350Z (2003-2006), and Nissan Pathfinder (2003-2004), all with the 3.5L V6 engine.","brand":"Mechman","offers":[{"title":"Default Title","offer_id":52662985720120,"sku":"B11051400M","price":649.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687505404.jpg?v=1784322471","url":"https:\/\/store.motormia.co\/products\/400-amp-alternator","provider":"MOTORMIA","version":"1.0","type":"link"}
