Universal / Custom

While we list these alternators as universal or custom, they are the same alternators we offer for OEM fitment applications. These specific alternators are your most common fitments for customers that have already purchased an accessory bracket system.  

These alternators are also the easiest to make custom mounts for and are operated with a single 12v switched source. Please use our technical drawings listed in the picture galleries of the alternator style you are looking to use. 

For optimal and reliable performance, please ensure you will be able to attain correct belt alignment, tension and wrap.  The higher the output power of an alternator the more grip to turn it will need.   If you have any questions or concerns, please contact us at [email protected]
