MECHMAN 250 Amp high output alternator for GM 2 pin w/RVC

The Elite series offers the highest possible amperage and durability available in a large case alternator. 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. This unit will achieve 180 amps at engine idle speeds and a full 250 amps at vehicle cruising speeds. This unit comes with a standard diameter pulley, making it perfect for high RPM and racing use.

This alternator is intended to be a drop-in replacement high output alternator that will reuse your OEM sized serpentine belt and have your OEM 2pin wiring connector plug in. Please be aware this alternator will still utilize the vehicles computer programming for voltage fluctuations between the parameters in the vehicle's computer. We highly advise adding (not replacing!) a power wire from our alternator directly to your battery positive post for best/optimal performance. We do NOT recommend adding a ground wire from the alternator to the battery in this application. Adding additional grounds in this application can cause irregular voltage readings and performance as it can dilute the signal being received by the vehicles OEM loop or current sensor on the OEM negative battery cable.

If you are wanting to have more control over your voltage, this alternator will pair nicely with our MM-VC1 GM 2pin voltage controller located on this website under the Voltage Control section.
