Brand new RMSTATOR Red Machined Aluminum Mosfet Regulator
Our new red machined aluminum Mosfet voltage regulator is a great upgrade for heat dissipation in any powersports charging system. After 10 minutes of use, our billet aluminum heatsink runs cooler by 33% than standard cast regulator housings. Our new red regulator, equipped with the renowned Mosfet regulation technology, is an added value to any three-phase permanent magnet charging system.
STOP BURNING YOUR REGULATOR RECTIFIER !
It is time to update or replace your voltage regulator with the advanced MOSFET type.
It runs cooler than all OEM diode style regulators. In addition, this rectifier has overheat protection, rather than burn up, it will simply turn off for a while and cool off.
- Direct replacement to your original unit
- Plug-and-play, direct fit, easy installation
- The quality exceeds the OEM equipment
- Improved heat sink and charging capabilities
- Higher grade of electric components
- All shipped products are tested
We have even included the opposite connector (main harness side) as we know these are often melted / corroded / defective and a major cause of repetitive electrical issues.
*All item pictures are accurate, if in doubt, do not hesitate and compare our item to your original part.
Before installing your new machined aluminum MOSFET Voltage Regulator Rectifier Bypass Kit :
- Check the AC output of the stator
- 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
Simply mount the new voltage regulator on your frame, plug in and route the harness directly to the stator connector and battery terminals, and you’re ready to ride.

DO NOT MANUFACTURE PARTS, DESIGN PERMANENT SOLUTIONS
We cultivate our actions towards finding permanent solutions. There is no way, us, as customers, would like to replace a part again and again. This mindset forces our team to design to fix, to conquer these pesky electrical failures in powersport.
GOOD DESIGN PRODUCE GOOD PRODUCTS. EFFICIENT DESIGN CREATES STELLAR PRODUCTS.
We are committing to innovate in finding clever ways to design more efficient parts that produce better results than any other part on the market.
WE ALL ARE CUSTOMERS ELSEWHERE.
In our shopping journey for buying our daily goods, we all expect to be treated with respect in a relation that makes us feel welcomed. Our team is encouraged to elevate that standard even higher and to provide all the information necessary for an easy and reliable installation.
OWN YOUR CUSTOMER PAIN LIKE IT IS YOURS
We own powersport rides ourselves. We feel the pain of dealing with unsolvable troubleshooting on our rides. We are committed in manufacturing complete solutions to known or I-would-never-have-suspected issues that are plaguing your rides... and ours.
