• Direct replacement: Designed to replace original units on a wide range of Touring models, saving time over custom repairs or fabrication.

Who It's For

This regulator is best for Harley owners of ELECTRA GLIDE, ROAD KING, ROAD GLIDE, STREET GLIDE and other Touring models from roughly 2008 through 2016 who want a direct, affordable replacement that matches the OEM part numbers 74505-09 or 74505-09a. It suits DIY mechanics who prefer a plug-and-play swap and riders looking to restore charging performance without buying dealer parts.
