HARDDRIVE H3108 Regulator for Harley-Davidson Dyna Models

The HARDDRIVE H3108 regulator is designed for select Harley-Davidson Dyna applications and meets or exceeds original equipment specifications. It fits 2008–2010 Harley-Davidson FXD Dyna Super Glide models, 2008 FXDSE CVO Dyna, 2009–2010 FXDFSE CVO Dyna Fat Bob models, 2008–2009 FXDB Dyna Street Bob models, and 2012–2013 FLD Dyna Switchback models.

This regulator uses a high-power, quality SCR (Silicon Controlled Rectifier) to support cooler operation. Its high-temperature, environmentally protected sealed encapsulation helps protect the component in demanding conditions. A late-technology circuit board is used for higher watt-density surface-mount applications where heat management is a major concern, helping minimize thermal impedance and conduct heat more effectively than standard designs.

The HARDDRIVE H3108 also features high-temperature and voltage OEM-grade wiring harness construction. It is identified as a black regulator and is referenced with OEM number 74631-08A. Choose this replacement regulator for a design focused on thermal performance, protected construction, and original equipment specification compliance.
