Description: 

This a new black finish GM style 120 amp alternator. This is a 1 or 3 wire hookup piece with internal voltage regulator. Will allow you to replace earlier alternators, allowing you to toss the external regulator and greatly simplifying your wiring. Only requires 1 wire going to the battery. Billet aluminum 1 groove v-belt pulley. 

New 120 Amp upgrade replacement alternator for GM 10SI applications.  This black alternator has an internal voltage regulator.Comes with a one groove bolt on V-belt pulley. 

High output, great for today's increased ignition, sound, and accessory power demands. No more dim or pulsating dash and headlights with that old tired stock unit!

It can be wired with a one-wire or three-wire set-up.
