Essential Service Screw for OPTIMA Differentials

The Kyosho OTW101-03 Ball Differential Screw is a purpose-made replacement for OPTIMA ball diffs, helping to maintain even preload and dependable engagement. Though small, it plays a key role in reliable differential operation.

Where It Fits and Why It Matters

This screw is tailored to the OPTIMA differential assembly and provides a firm seating for the ball diff parts, reducing slippage and helping the drivetrain deliver consistent power transfer. It is ideal for routine servicing and rebuilds.

Quick Tips for Correct Installation

Ensure all mating surfaces are clean before installing the Kyosho OTW101-03 and start the screw by hand to prevent cross-threading. Tighten to a controlled feel and inspect regularly to avoid premature wear affecting diff performance.

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.

Will this replace the original part on older OPTIMA cars?

Yes, provided the differential housing and components are unmodified, the OTW101-03 replaces the original screw on earlier OPTIMA variants.

Do I need any special tools to fit it?

No special tools are required beyond a suitable screwdriver and a clean workspace. Hand-start the thread then nip up to the feel you use for your diff setup.
