This 3Racing V3R-0822 is a hardened aluminum 22T second gear produced for Kyosho V One RRR and V One RRR Evo 1/10 scale touring car gearboxes. It is an RC-scale replacement part intended to restore or adjust the gearbox toothset with a material chosen to resist wear compared with standard alloy options.
Installation follows standard gearbox service practice: remove the gearbox cover, extract the old second gear and bearings as required, and press the replacement gear onto the shaft or into the carrier using suitable tools. Check mesh and endplay after fitting, verify bearing condition, and run-in at low power before full use.
In tuning terms this 22T hardened aluminum second gear is a maintenance and durability item rather than a performance modifier; it is used when replacing worn teeth or when a stronger tooth surface is needed to withstand high mileage or heavier drivetrain loads during track sessions.
