Have ordered many alternators from Autotech, never had an issue. Triple 370amp on my Tahoe, Quad 400 amp going in my suburban. Wouldn’t go with anyone else. Shoutout to Nick Regnier for helping me get them ordered and install.

Extremely great service top of the line equipment. huge shout out Nicholas Regnier for helping once again on getting me the alt and making sure I installed it correctly and that the alt would fit just right. I just replaced my gold series witch still preformed perfect well after 3years to a competition series.
