- The 32 Amp system features a series type regulator/rectifier that unloads the stator when the battery is at full charge letting the engine spin easier than the OEM shunt type which creates a constant drag. This not only extends the life of the charging system, it increases fuel mileage and frees up horsepower
- The rotor has been upgraded with an improved method of gluing the magnets to prevent them from coming off like the OEM rotors are known to do
- The rotor can be used as a replacement rotor for the OEM 22 Amp and 32 Amp charging system, but also works in conjunction with the Compu-Fire 32 Amp and 40 Amp charging systems
