Keep your OPTIMA diff sealed for reliable handling

The Kyosho OT223B gasket set supplies replacement seals for the OPTIMA differential, helping to prevent oil escape and keeping the diff running smoothly for predictable handling on the circuit.

Use in workshop tune ups

These gaskets are a useful part when rebuilding differentials during a service. Installing Kyosho OT223B seals can prevent performance drift caused by leaking or degraded seals.

Fitment details and quick service

Intended for the OPTIMA series, the gaskets match the diff housing form and are easy to fit during normal maintenance. They are a practical spare for anyone who services their own cars.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Do these gaskets affect diff tuning?

Gaskets themselves do not change internal tuning, but a proper seal ensures diff oil remains at the intended level and viscosity, which supports consistent tune behaviour.

How often should I inspect the seals?

Check seals during every major service or if you observe oil traces on the chassis. Regular inspections catch issues before they affect performance.

Are replacement gaskets an easy upgrade for club racers?

Yes. Replacing old gaskets is a straightforward maintenance task that club racers can do between sessions to retain reliable diff operation.
