Battery condition is extremely important. No stator or regulator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.

Brand New Aftermarket Evolution Dyna & Softail 3-Phase Upgrade Kit

We love older Harleys at RMSTATOR, but we all know they are a bit antiquated. Engines from 1970-2005 used a single phase stator and extremely dated voltage regulator design. The single phase stator is VERY RPM dependent for output, producing little to no power below 2000RPM, and limited power overall. The OEM style SCR switched shunt type voltage regulator was inefficient and generated massive heat in use, along with poor grounding through the case frame mount. We decided to bring these bikes into the future by updating the charging system to a 3 phase stator and modern series voltage regulator for more power and increased reliability. The 3 phase stator design uses 3 coils that overlap output and are no longer severely RPM dependent, generating charging power from 1000RPM at idle on up to redline! The series type voltage regulator provides efficient and accurate voltage regulation while lowering stator winding temperatures for increased life. It comes in our billet aluminum CNC machined housing with custom powder-coated steel mounting bracket unique for each chassis, and a new wiring harness for direct connection to your battery.  Keep your older HD on the road forever with an RMSTATOR 3 phase upgrade!

This system has been designed and developed in house, and battle-tested on Shovelheads, Evolution Big Twin and Sportsters, and Twin Cams over tens of thousands of miles of road testing. You will not be disappointed!

Benefits:

  • Significantly improved low RPM charging output
  • Increased overall charging power output
  • Modern series voltage regulator lowers stator winding temperatures
  • Direct to battery wiring harness for maximum power output
  • Increased power and reliability in one kit

Stator:

  • Highest grade of lamination materials
  • Highest grade of copper winding, resistant to 200 degrees Celsius
  • Connectors included
  • Rubber grommet included

Flywheel:

New RMSTATOR heavy-duty flywheel rotors for Harley Davidson motorcycles are a well-priced solution to problems with the OEM flywheel, and an excellent alternative to all the mechanical troubles you can encounter with a repair.

Features

  • Built to OEM size
    Fits precisely in your ride: install it and forget it.

  • Improved epoxy
    Uses high temperature epoxy that is stronger than OEM, eliminating the possibility of magnet detachment.

  • High grade steel capping
    Prevents harsh additives in motor oil from degrading the epoxy attaching the magnets. Though extremely unlikely, if a magnet did ever come loose, it would remain in the sleeve preventing contact with the stator.

  • Precise balancing
    Eliminates crankshaft vibrations for longer engine longevity.

  • Shop with confidence
    One year warranty. All products are tested.

Don't waste time with temporary solutions, and start fixing your ride like a pro!

Series Regulator:

SERIES regulators run much cooler than the Shunt and MOSFET voltage regulator rectifier and way much cooler than OEM parts.

Moreover, the regulator has our new machined billet aluminum casing which dissipate heat 33% better than standard molded casing.

Power only flows through the electrical components when the battery is charging.

Allows the stator to have lower current flowing when not used, extending its lifetime.

The regulator is easier to mount because it is smaller than the OEM one.

ABOUT THE SERIES VOLTAGE REGULATION TECHNOLOGY

RMSTATOR’s new SERIES voltage regulator brings better reliability and charging system performance. A SERIES regulator is a significant upgrade over typical shunt type voltage regulators.

A shunt regulator controls battery voltage by grounding the stator coils to dissipate current as heat, rather than sending it on to the battery. SERIES regulators control battery voltage by intermittently disconnecting stator coils from the regulator electronics, limiting current flow through the unit and on to the battery completely.

This results in lower regulator and stator temperatures, more accurate voltage regulation, and increased reliability of your charging system components.

This kit includes:

  • 3-Phase Upgrade Stator
  • Conversion Harness
  • 50A Machined Aluminum Series Regulator
  • Regulator Mounting Bracket
  • Improved Capped Flywheel

Installation

Before installing your Evolution Dyna & Softail 3-Phase Upgrade Kit

  • Replace any burned or corroded connectors on stator and regulator rectifier
  • Check and repair any melted wiring
  • Use hi-temp dielectric grease on all connectors

Our stator might have a different wire color code than your original part.
All the wires are installed in the correct order; please do not change any of the wiring configurations.
This stator is designed as a direct plug-in replacement and should be used as such.
When bolting stator in, always use locking compound.
If our stator includes a pickup coil, always make sure the air gap is correct upon installation; we suggest as close as possible but no less than 0.010".

Warning:

Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
