• (1) MechMan 400 Amp High Output Alternator

Built for serious electrical demand, this Mechman 400 amp alternator delivers massive output without sacrificing reliability. Designed for custom applications, it combines modern 6-phase hairpin technology with a more budget-friendly cast case that can be painted or customized to match your engine bay.

This unit is capable of producing up to 200 amps at idle and 400+ amps at cruising speeds, making it ideal for high-performance audio systems, competition builds, and heavy electrical loads.

The included 46mm 9-rib pulley allows for fine adjustment in custom setups, helping you achieve proper belt alignment where precision matters. A universal adapter bolt, nut, and spacer are also included to assist with installation across a wide range of bracket configurations.

For optimal performance, a strong mounting bracket, proper belt wrap, and a high-quality belt are critical to handling the increased load of this high output alternator.

A P101 harness is included and requires only a 12V key-on source for operation. For users looking to increase charging voltage beyond 14.8V, optional voltage boosting plugs are available separately and can safely raise output to 16+ volts.
