“You guys have the best alternators I have ever used! I'm pumped, I just got my second alternator in the mail today. JS Alternators are the real deal people! Fast service, too!”
“My cars lights no longer dim and over 3000 watts in the system, it’s fantastic! I’m just honestly grateful for such spectacular service and products. Thanks JS Alternators."

"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!"
