Charging - System - 40A

Provide 25A at idle and 40A continuously above 2800 rpm. Unique narrow rotor and stator fit into Softail/Dyna/FLT primary cases as used by most custom builders and the voltage regulator bolts on the stock location without any frame modifications. Precision-balanced vented rotor keeps the stator cooler in closed primary systems to maintain maximum output under all high-current draw conditions. Custom-designed flanged seal spacer provides maximum support for the rotor. Voltage regulator output is calibrated to 14.25V from idle on up. Ideal for fuel-injected engines and bikes with overdrive-type transmissions. Made in the U.S.A..
