About This Product
This Compu-Fire voltage regulator is a heavy-duty 32-amp unit designed to keep your charging system stable and reliable. Finished in black, it is a direct fit for 1989 to 1999 Evolution Big Twin models. Please note that it excludes 1995 to 1996 FLHTCUI, 1996 FLHRI, FLTCUI, and FLHTCI models, as well as 1997 and later FLT models. It replaces OEM number 74519-88A. A failing regulator can lead to battery issues and frustrating electrical gremlins, so upgrading to a quality Compu-Fire component is a smart move for any Evo rider. This regulator is built to handle the heat and vibration of the road, ensuring your Harley's electrical system stays within the correct voltage range for optimal performance and battery life.
Manufacturer part number: 55120.
