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 charging system.
