Convert your tired old charging system with our internally regulated 120 amp 100% made in the USA unit! This is a massive improvement from the stock (35/45 amp) alternator and a crucial upgrade when running a high output ignition system, auxiliary driving lamps or an EFI conversion.

Simple “three wire” installation eliminates the OEM external regulator, while retaining function of the “charge” light on the dash.

Comes with insulated stainless steel bracket, wiring harness & hardware.

Simply disconnect the plug to your external voltage regulator and connect the blue wire to our pigtail harness. power wire connects direct to starter motor post, ground to engine block.
