Customer Reviews

Look and Runs Amazing

Brandon Manis, April 2022

Every single audio build I’ve done always has a JS alternator. Great customer service, amazing pricing, very fast shipping, got my alternator within a week and it’s a pretty rare car so I was surprised at the speed they had my alternator built and shipped out to me. Amazing company and I will continue to use them and represent them on all of my builds, highly recommended and very good quality product.😌 (also their powder coating is perfection)

Very Nice Alternator

Paul Nelson, March 2022

I will not consider going anywhere else for my high output alternators. 10.5kw of bass amps on my daily driver and I do not lose even a thenth of a volt while driving at full tilt! Two vehicles and two alternators and zero problems with the alternators, customer support, or shipping times. Customer for life here! Do not hesitate. 👍

Super Impressed

Kino Hicks, April 2021

Just got mine and super impressed. The customer service was very helpful and I would encourage anyone who needs a high output alternator to use these guys!!!

They're so great they even shipped out my made to order alternator on New Year’s Eve.

Petey Parado, May 2021

Ordered my alternator a week before Christmas 2020.They emailed to confirm my address in Hawaii. I emailed back and they responded quickly.There so great they shipped out my made to order alternator on New Year’s Eve. I received it on the 4 of January 2021. It came with everything I needed. Shorter bet I got from local auto parts store.your JS ALTERNATOR made my sound system very happy voltage stays above 14v. THANKS,Jonathan from Kauai Hawaii..
