Stay Sparky

The Hoover Dam uses alternators.  These churn out just a few more volts than your vehicle requires, but the concept is the same.  When your beast is tuned for high performance, it seems like you need all the spark the Hoover Dam can generate.  That's where a performance alternator comes in.  High performance alternators are designed to be lightweight and efficient, all the while providing the high output you need.

Learn More about Alternators

An alternator is a small generator attached to your engine that charges your battery and powers your system.  You know this.  But what you might not have realized is how much of a difference a high output alternator makes.  Performance, high output alternators are not only designed specifically for the intensity of your application, but are also lightweight and efficient. 

Street Side Auto provides our customers significant savings and a superior online buying experience on all Alternators. We are proven to be a cut above the competition by offering a low price guarantee, free shipping*, and all-American tech support for Alternator information you may need about Alternators and other Alternator products.

  • Why don't we show the price?

    When a manufacturer implements a Minimum Advertised Price (MAP) policy, they create limits on the list price that retailers are allowed to advertise their products for. In line with our efforts to continually provide the lowest possible price, we've made it easier for you to inquire about our Exclusive Pricing on these MAP items.

  • Shipping Policy

    Free Ground Shipping
    Free FedEx ground shipping on all orders over $50. Free shipping to 48 Continental United States only. Orders under $50 will incur a FedEx ground shipping charge of $9.95.

    $9.95 Per Wheel/$25 Per Tire
