Mechman 320 Amp Alternator for 2021-2026 Ford 2.7L, 3.3L & 3.5L Truck

This Lin Bus Compatible Elite Series Alternator delivers exceptional output and durability in a heavy-duty large-case alternator. Six-phase technology, massive twin rectifier assemblies, and 12 heavy-duty diodes provide the strength and thermal capacity needed for reliable daily use while maintaining excellent output throughout the operating range. These impressive alternators produce 180+ at engine idle RPM and 320+ amps at cruising speeds Designed for vehicles with increased electrical demand, this alternator provides the additional charging capacity needed to support high-powered audio systems, auxiliary lighting, aftermarket accessories, and other demanding electrical loads. Its high-output design helps maintain stronger system performance under load while providing faster battery recovery when additional charging capacity is required. Like most high output alternators, this unit comes with a smaller diameter pulley, and will require a 1/2 inch to one inch shorter than stock length belt for proper belt tension in most applications.
