I ordered a alternator for my older **** truck no problem they took my money immediately, several days later I get a email that my order was refunded. I contacted the company and they said they don't make a alternator for thst truck,why did they take my Money? Anyway a week later they still haven't returned my money. I would be very cautious buying from this company.

Thank you for reaching out. It looks like we have already submitted the refund for this order on October 9th and have been in correspondence with you regarding the refund. Unfortunately refunds are not automatic and do take time to process. We do apologize again for the inconvenience.

I purchased a 320 amp alternator from this company. The shipping was EXTREMELY FAST!! Regardless of other reviews left. I followed the instructions Exactly how they said "through a series of well detailed emails" Customer service is extremely fast in responding and very courteous. Their products, are as described and have exceeded my expectations.

Pretty good, I don't have much experience with different alternators but from what I can tell they are good. I have a pretty obscure model car that doesn't have much room for modification. JS is one of two companies that sells HO alternators for my car. Shipping only took one day, which I was pleasantly surprised by. When I went to install it, it was missing two pieces, which I believe they fixed because the pieces now appear in the picture on their website. It wasn't too much of an issue, it just took some effort to remove said pieces from my old alternator. It works much better for my audio purposes, and they responded quickly when I had concerns about my battery light (although I missed their response and didn't see it for a few days). It has however given way to new issues. I believe they were existing issues so while the new alternator made them worse, it also helped me notice them. My audio now works much better and doesn't dim the lights, though my power windows now do, and turning on the A/C causes belt noise. Of course, most of my issues could be due to user error as I installed it myself and had the plug incorrectly wired for a couple of days before realizing when it caused my battery to die. Overall, I'd say the alternator has been a good upgrade for me, though it was quite a hassle.
