The Kyosho IFW621-02 steel differential bevel back washer is made for RC setups that run 12T and 18T bevel gears. It is a dedicated component for the Inferno MP Series, including MP10 and MP10T, helping to preserve correct gear engagement and drivetrain balance.
This part is intended for the Inferno MP Series and secures the bevel gears inside the differential housing. Racers and hobbyists who demand predictable handling will appreciate the added stability it brings to the gear train.
Fit the Kyosho IFW621-02 so it sits square to the bevel gears and check the mesh after installation. Routine checks and gentle cleaning will prevent grit build up and extend the washer and gear life.
