Harley Voltage Regulators
A failing regulator cooks batteries or leaves you with a dead one. We stock replacement regulators from Cycle Electric, Drag Specialties, Compu-Fire and V-Factor.
- Solid-state replacements: Drag Specialties by model for Dyna, Softail, Sportster, Touring and '18 and up M8
- Evo: '81–'88 and '89–'99 Big Twin regulators
- Vintage: Cycle Electric 12 volt regulators for '65–'81
- No battery: Cycle Electric universal regulators for kick-only choppers
The regulator works with the stator and rotor, so test the whole charging system before you buy. See starters and engine parts.
Not Sure It Fits?
Year, model and charging system all matter. If you can't tell whether something fits your bike, hit us up with your year and model and we'll check it before you order.
