Alternators & Alternator Kits
One of the most important systems in nearly every automotive application is the electrical system. It is required to start the engine, power the ignition, as well as lighting, gauges, HVAC, wipers, and other components in need of voltage. To keep the battery charged while driving, a charging system is required. The main component in the charging system is the alternator. This belt-driven component replenishes any power used by the vehicle while the engine is running. When additional electrical parts are added to the vehicle, more amperage is needed to keep up with demand. Performance alternators are designed to provide additional electrical power as well as a unique look to compliment the other engine components under the hood of your race or show vehicle. JEGS offers upgraded alternators for sale from top manufacturers like Powermaster, Proform, Speedmaster, Tuff Stuff, JEGS, and others. View our wide selection of the best alternators for cars and trucks, which will keep your electrical system charged while looking good under the hood of your vehicle.
What Are The Benefits Of Buying Performance Alternators?
Upgrading the alternator in your car or truck provides more than one benefit. The first is increased charging capability that is necessary when additional electrical components are added to the vehicle. Upgrading to a custom alternator instead of a factory replacement also allows you to change the finish and improve looks under your vehicle's hood.
Increased Charging Capability
Performance car alternators are designed to provide increased charging output that will maintain your vehicle's electrical system and battery when additional electrical components are added such as stereo systems, electric cooling fans, ignition boxes, fuel pumps, and other parts. Alternators are available with power options between 80 amps and 300 amps are available with a built-in / internal regulator.
Available Finishes And Designs Compliment Your Engine's Looks
Performance alternators are offered in different finishes, including polished, chrome-plated, black, and more. This allows you to customize the look under your vehicle's hood and compliment other engine components. In addition, custom alternators are available in different styles, allowing you to upgrade from a V-belt to a serpentine belt, external to internal fan, and from a classic to modern look.
Once the engine begins running, the alternator is responsible for keeping the battery charged and electrical system at the proper voltage level. When shopping for a replacement alternator, it is important to understand how they work, how long they last, as well as how to repair them. To help you along the way, we have provided the answers to the below questions about alternators.
How Do Alternators Work?
An alternator is a belt-driven component that is mounted to the front of the engine. When the engine is running, the pulley shaft spins a group of magnets around a coil, creating AC voltage. The AC voltage is then converted to DC voltage through the alternator rectifier, which is then connected to the battery. This voltage is used to power the electrical system and keep the battery at the properly charged level.
How Long Do Alternators Last?
In most cases, factory-style alternators last between eight to ten years and up to 150,000 miles. The amount of time can vary, depending on the operating conditions.
Why Do Alternators Go Bad?
There are many factors and reasons that cause alternators to go bad. Some of these include moisture, corrosion, excessive engine bay heat, poor quality materials and assembly, improper belt tension, as well as general wear and tear.
How To Repair Alternators
In most cases, factory-style alternators last between eight to ten years and up to 150,000 miles. The amount of time can vary, depending on the operating conditions. Depending on the type, the steps to rebuild alternators will change. However, for most applications, the first step is to disassemble the alternator fan, pulley, and spacer from the main alternator shaft by removing the main nut. Next, the housing bolts are removed to separate the two halves and then access the internal parts. Most internal parts are either bolted or pressed in place. The main parts of an alternator that can be replaced include the following:
