The Heart of Your Electrical System
Car audio and electronic enthusiasts often fill their vehicles with TV screens, lights, audio equipment and other aftermarket accessories causing their vehicles to create huge draws of power. Owners often upgrade their hood battery or add additional batteries in the trunk of the vehicle in hopes of satisfying the demand, but don’t understand that the alternator is the heart and power plant of their electrical system.
Don't Skimp on What's Important
There are various options currently on the market to replace and fix stock alternators. Many of them are using used and remanufactured parts in an attempt to make a quick buck. The result is a sub-par product that doesn’t retain OEM functionality or reliability. US Alternators is one of the few companies on the market to use new OEM parts you can depend on.
What Our Customers Are Saying
I highly recommend US Alternators to any serious audiophile. Daniel has displayed the best customer service imaginable. My hairpins are exactly what I was hoping for. They supply my setup with more than enough power.Adam
Couldn’t be happier with my 250a US Alt. On my Nendo bc3500 I don’t drop under 13.8v full tilt. I paid a pretty penny to get all the bells and whistles, but it was worth it. I recommend US Alts to anybody. #1 customer service.Billy
I love my US Alternator. My 240a is definitely of high build quality. My voltage holds steady under load. Daniel has always been fast to reply with any questions I have and to be honest, I’d never go with any other alt brand.Trevor
During the whole order process, Daniel kept me very updated about my alt. He responds quickly to all my questions. I’m digging the durable, high-quality parts. I’ll be getting a 2nd alt soon. US Alts is my #1 recommendation!Carl
US Alternators is the best by far with the quality of production of high-output alternators. I am totally satisfied! Especially with the outstanding customers service Daniel has provided. I am proud to have 250a alt for my ’13 Fiesta.Ismael
At first, I was hesitant to go with US Alternators due to the cost. But as soon as I made the purchase, I knew I had made the right decision! Daniel bent over backwards to help me get my alternator right. He makes an amazing product.Brayden
