RM STATOR Regulator/Rectifier - Mosfet - 1941-1986 Harley-Davidson RMS021-108810

Regulator/Rectifier - Mosfet - '41-'86 Harley-Davidson®

The RM STATOR Mosfet Regulator/Rectifier is a direct replacement for the original unit on select Harley-Davidson motorcycles. Manufacturer part number RMS021-108810, this plug-and-play component is designed for direct fitment and easy installation.

Built with higher-grade electrical components, improved heat-sink construction, and enhanced charging capabilities, the regulator/rectifier is designed to run cooler than a traditional voltage regulator/rectifier. Its Mosfet technology helps lower operating temperatures for extended longevity and supports reliable performance.

The design reduces load on the stator, which can require less work from the charging system and help reduce fuel use. It also helps extend battery life and cold-cranking capacity while removing stator load to support increased engine power.

Fitment includes the 1969 Harley-Davidson 1200 Electra Glide FLH; 1959-1962 Harley-Davidson Duo Glide FL; 1958 Harley-Davidson FLH Duo-Glide; 1971-1972 and 1983 Harley-Davidson FLH Electra Glide; and 1986 Harley-Davidson FLST Heritage Softail. Distributor part number was not provided.
