Refine OPTIMA Performance with Kyosho OTW101-01

The Kyosho OTW101-01 Ball Differential Gear is a focused upgrade for OPTIMA chassis, offering improved feedback and steadier traction under load. It helps reduce abrupt grip changes and lets drivers fine tune slip characteristics.

Key Tuning Traits

This ball differential provides precise adjustments to differential action so you can balance turn-in, mid corner grip and exit behaviour. The engineered parts aim to maintain settings through extended running and provide consistent feel.

Why Racers Choose This Unit

Racers select the OTW101-01 for its combination of adjustability and robust construction, which stands up to frequent use. Its compatibility with OPTIMA assemblies makes it a direct path to better predictability on the circuit.
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.

Does the OTW101-01 need break in?

A short running-in period with moderate use helps seating of the internal parts; check and adjust preload after the first few sessions for best results.

Is it compatible with aftermarket slipper setups?

Compatibility depends on the specific components, but the OTW101-01 integrates with common OPTIMA driveline parts; verify clearances and spline sizes when mixing brands.

Which grease should I use inside the diff?

Use a light diff grease or oil recommended for ball differentials to preserve smooth action; avoid heavy pastes that limit fine adjustment and responsiveness.

How often should I inspect the unit?

Inspect after every few races or long practice days, looking for wear on balls, races and seals, and re-lubricate to keep performance consistent.

Can this diff affect tyre wear?

Yes, changes to differential behaviour alter power distribution and can change tyre scrub; proper setup will balance handling benefits against potential tyre wear.
