Description
If you’re running a fuel-injected Softail, Dyna, or FLT with a custom primary setup, charging system reliability becomes critical—especially under high electrical demand. The COMPU-FIRE Vented Rotor 55406 delivers consistent alternator output by keeping your stator cooler in closed primary configurations, eliminating voltage drop when you need it most. Its narrow profile drops directly into stock primary cases without frame modifications, making this a genuine bolt-on solution for serious builders.
Built for engines pushing maximum current draw and overdrive transmissions that demand stable charging, this U.S.-made rotor is precision-balanced to minimize vibration and maintain peak performance across the entire RPM range.
