“I normally don’t bother myself with going on to leave feedback comments on goods purchased but I have to make an exception in this case. I ordered a 240 amp alternator sometime last year. My voltage has been steady above 14 volts since upgrading. It is one of the best improvements I have done for my car.”

“I recently installed two of your 320 amp alternators on my Tahoe and a 240 amp on my Toyota. It’s amazing the clear cut power difference I’ve observed! Thank you for your hard work and quality products! I’m sold and highly recommend your product!”
