Customer Reviews

2012-2021 Jeep Wrangler 250 to 425amp Alternator.

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. πŸ‘
