Now an alternator that provides high outputat low RPM!
We use a special GM style case and beef it up to provide 160 amp max and 110 amp at idle. This is enough output to power electric cooling fans, compressors, halogen lights, and most stereo systems.
This alternator is a direct bolt-in replacement for the earlier GM 10SI (internally regulated) and 10DN (externally regulated) alternators, it will fit most straight across mounting brackets from 1963 - 1987. It is only 5" deep from the front edge of the mounting ear to the back of the output stud.
This is a true 1-wire alternator and will turn its self on without having to raise the engine RPM initially. This makes it perfect for hot rods, custom vehicles, and is very durable for off-road use. Also available as a plug-in version for use with an idiot light. Just ask us for the plug-in version in the comments section during checkout and we will include a harness.
Please let us know if you would like a single V-belt, double V-belt or serpentine pulley installed.
