The Mechman E Series is a 400 amp large-case alternator built for 2005–2013 GM trucks. It uses six-phase technology, twin rectifier assemblies and 12 diodes, and holds 200+ amps at idle, far above the stock alternator. It swaps the OE two-pin ECU-controlled regulator for a more robust four-pin unit and bypasses GM's RVC charging system, so voltage no longer swings with computer control and no check battery light comes on. It suits owners running big audio systems, winches or other heavy electrical loads; the trade-off is a 1.75-inch pulley that needs a shorter belt and a custom build lead time.

This is a 400 amp billet alternator in an orange finish, built for 2005-2013 GM trucks.
It uses 6 phase technology with twin rectifier assemblies and 12 diodes. It maintains 200+ amps at engine idle speeds. It uses a 4 pin style regulator, which is more robust than the OE 2 pin ECU controlled alternator. It bypasses the RVC charging system on all 2005 and newer GM truck applications, so there is no check battery light and no computer controlled voltage swings.
The alternator has a smaller 1.75 inch diameter pulley, so it needs a slightly shorter drive belt for proper belt tension. Mechman builds each unit to order.
