Swap in ceramic balls for steadier differential performance

The Tamiya 42194 3/32 Ceramic Differential Balls (12pcs) are a direct replacement for ordinary steel balls, intended to lower wear and keep the ball differential running smoothly under regular and competitive use.

Designed for a range of TRF chassis

This 42194 set fits a number of Tamiya models, including TRF201, TRF502X, FF-03 and FF-03PRO, making it suitable for drivers who maintain several cars or swap parts between setups.

How ceramic improves diff behaviour

Ceramic balls provide a harder contact surface and reduced friction compared with steel. That combination helps the diff maintain consistent internal action and slows down wear on mating surfaces over time.

Are these balls pre-lubricated?

No, the balls are supplied clean. Apply your preferred diff grease or oil during assembly to ensure correct operation and protection.

Do they need a break-in period?

Ceramic balls typically settle quickly. Run a few light sessions to bed them in and recheck diff feel before a full race or long session.

Will they corrode like steel?

Ceramics do not rust like steel, but surrounding metal parts can still corrode. Keep metal races and housings clean and greased to prevent corrosion.

Can I use them on nitro and electric cars alike?

Yes, the balls suit both nitro and electric Tamiya models that use 3/32 ball differentials. Ensure the rest of the drivetrain is compatible with the increased hardness.

How do I know when to replace the balls?

Replace them if you notice rough spots, increased diff play, or visible chips. Regular inspection after heavy use will reveal any issues early.
