These units are perfect for upgrading the old, low amperage units in older muscle cars and classics.  You get newer technology and are able to ditch the external regulator!  They are available in 130, 200 and 250 amp ratings. 


These alternators come with a 1 wire (self exciting) regulator so there's no wiring to fuss with.  Simply attach the main charge cable and you're done.   


Please specify what type of pulley setup you are running so we can install the correct pulley for you.  


We offer these in plain cast or for show cars we have optional powder coat and mirror polished finishes. 


**Unit shown is with optional black powdercoat finish.  Units come standard in cast aluminum or raw finish**
