A Harley regulator/rectifier is a charging-system part matched to a particular model year, stator output and connector layout—not a universal chrome box. Start with the factory part number, year, model family and the number and style of plugs before considering an upgrade. MOSFET replacements can offer improved heat management, but only if their fitment matches the motorcycle. The products below are deliberately separated by application; verify the connector, mounting points and stator rating against the service manual before ordering.

The picks, in detail
Harley-Davidson Chrome Voltage Regulator 74567-11
Genuine Harley chrome regulator for 2011–2017 Softail models. It is sold individually and is a cosmetic-finish OE replacement, not a universal regulator for every Twin Cam.
- OE part 74567-11
- fits 2011–2017 Softail
- triple-plated chrome finish
- Factory application and fitment checker
- One-year limited warranty
- No stated MOSFET upgrade claim
- Does not fit Dyna, Touring or Sportster by this listing
RMStator RM30515 MOSFET Regulator/Rectifier
A MOSFET regulator/rectifier listed for 2014–2022 Harley-Davidson Sportster motorcycles. It is a ride-specific, plug-and-play replacement rather than an interchangeable Sportster part across all years.
- MOSFET regulator/rectifier
- 2014–2022 Sportster fitment
- RM30515 part number
- Current retailer price observed
- MOSFET construction is specified
- Confirm exact Sportster variant in the retailer fitment tool
- Not for pre-2014 Sportsters
RMStator RM30342 MOSFET Regulator/Rectifier
RM30342 is the RMStator MOSFET unit listed for 2009–2013 Sportster models. It keeps the older 2009–2013 connector/application distinct from the later Sportster option.
- MOSFET design
- 2009–2013 Sportster fitment
- RM30342 part number
- Exact year band is published
- Direct-fit product family
- Not a 2004–2006 or 2014-up Sportster regulator
- Verify stator and plug before installation
RMStator RM30345 MOSFET Regulator/Rectifier
This MOSFET RMStator regulator is listed for 2004–2006 Harley Sportster models, separating the 22-amp-era application from the later 32-amp Sportster electrical system.
- MOSFET regulator/rectifier
- 2004–2006 Sportster fitment
- RM30345 part number
- Application-specific aftermarket replacement
- Observed retail listing supplies price
- Wrong for 2007-up 32-amp Sportsters
- Never infer fitment from the common Sportster name alone
RMStator RM30341 MOSFET Regulator/Rectifier
RM30341 is the MOSFET replacement listed for 2008–2017 Harley Dyna models. It is the Dyna-specific choice, with a different application from the Softail product even where years overlap.
- MOSFET construction
- 2008–2017 Dyna fitment
- RM30341 part number
- Specific Dyna year coverage
- Ride-specific retailer listing
- Not for 2006–2007 Dyna
- Confirm connector count and OEM reference before purchase
RMStator RM30930 MOSFET Regulator/Rectifier
A separate RMStator MOSFET regulator for 2006–2007 Dyna motorcycles. The narrow year split matters because it is not the same listed part as the 2008–2017 Dyna unit.
- MOSFET regulator/rectifier
- 2006–2007 Dyna fitment
- RM30930 part number
- Avoids an overbroad Dyna claim
- Current product listing identifies the exact band
- Not for 2004–2005 or 2008-up Dynas
- Check the motorcycle’s original regulator connector
RMStator RM30928 MOSFET Regulator/Rectifier
RM30928 is listed for 2007 Softail motorcycles. Its one-year application is a useful warning that a 2008–2017 Fat Boy/Softail regulator should not be assumed to back-fit.
- MOSFET design
- 2007 Softail fitment
- RM30928 part number
- Exact application rather than generic Softail language
- Published MOSFET upgrade type
- One-year fitment requires careful VIN/year confirmation
- Not the 2008–2017 Softail unit
RMStator MOSFET Regulator for 2008–2017 Fat Boy
A MOSFET regulator/rectifier listed for 2008–2017 Fat Boy applications, with two plugs and five pins specified by the seller. The published charging-voltage specification is 13 V plus or minus 0.5 V.
- MOSFET regulator
- 2008–2017 Fat Boy fitment
- two plugs, five pins
- Seller publishes connector count and voltage target
- Overheat-protection claim is stated
- Fitment must still be confirmed against exact FLST model
- Do not use a pin count alone as fitment proof
Rick’s Motorsport Electrics OEM-Style 10-904B
Rick’s 10-904B is an OEM-style rectifier/regulator listed for 2007 Harley Touring 1584 models including Road Glide and Electra Glide applications. It is an OE-style option rather than a claimed MOSFET conversion.

The Hot Shot 10-940H is Rick’s higher-priced regulator/rectifier listed alongside 10-904B for 2007 Touring 1584 Road Glide applications. Use the vehicle finder to confirm the exact harness before treating it as an upgrade.
- Hot Shot regulator/rectifier
- listed for 2007 Touring 1584 Road Glide
- 10-940H part number
- Application appears in Rick’s vehicle finder
- Premium alternative within the same fitment search

Buying tips
- Diagnose battery, stator AC output, grounds and connectors before replacing a regulator; a new unit cannot repair a damaged stator lead.
- Match the OEM number, model year, plug style and stated amperage system. Cycle Electric identifies 2007–2014 Sportsters as a 32-amp application, for example.
- Disconnect the battery before service and route the output lead exactly as specified; damaged regulator wiring has prompted Harley recalls on some models.
