COMPU-FIRE Charging - System - 40A 55565

If you're running fuel injection or an overdrive transmission on a Softail, Dyna, or FLT platform, your stock charging system likely can't keep up with the electrical demands of modern builds. The COMPU-FIRE 40A Charging System delivers the sustained output your bike needs without frame modifications or custom fabrication. Built for reliability and precision, it maintains consistent voltage under high-current conditions where lesser alternators fall short.

This system is engineered for custom builders and performance enthusiasts who demand real results. The precision-balanced rotor and integrated voltage regulation eliminate the guesswork, while the U.S.-made construction backs up every claim.
