Description

The Mechman 8302400 is a 400-amp high-output alternator designed for 2005-2013 GM Trucks and SUVs.

This Elite series alternator features 6-phase technology, twin rectifier assemblies, and 12 diodes for durability. It produces 180+ amps at idle and 400+ amps at cruising speeds. The unit includes a smaller diameter pulley, requiring a shorter drive belt for proper tension. It also bypasses the OE RVC charging system with a 4-pin regulator, providing stable voltage output.
