$699.00
The Mechman Billet Elite series 400 amp alternator offers great output at idle RPM and excellent durability in a direct-bolt-in package. 6 phase technology, combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining great output at low RPM. These alternators will make 180+ amps at engine idle speeds with a full 400+ amp output at cruising speeds. HOT RATED!
This unit comes with a smaller diameter pulley and will require a 1/2″ to 1″ shorter than stock length belt for proper tension in most applications. Includes the RVC Bypass Kit – full details below.
Fits a variety of late model GM trucks and SUVs with both gas and diesel engines – see below for complete list!

Installation Notes
Drive Belt
This unit comes with a smaller 1.75″ diameter pulley and will require a slightly shorter drive belt for proper belt tension. Not recommended for sustained use above 5,000 RPM. If you DO NOT use the correct shorter belt, this will result in very low to no output and create extra work load for the alternator.
RVC Bypass
This alternator uses the more robust 4 pin style regulator than the OE 2 pin ECU controlled system. There is no extreme voltage fluctuation as this will bypass the RFC charging system in all truck & SUV applications. Simply install the 1 wire P101 harness to a verified 12V switched source and plug in the included P103 module into the connector which originally plugged into the alternator. No check battery light, no computer controlled voltage swings. The voltage you want, when you want it!
