Upgrade your ball differential with Tamiya ceramic bearings

If you want a tidy upgrade that reduces internal wear, the Tamiya 42194 3/32 Ceramic Differential Balls (12pcs) swap in for conventional steel balls to help deliver smoother running and longer service life in ball diffs.

Compatible with several TRF platforms

The 42194 set suits many Tamiya platforms, including TRF201, TRF502X, FF-03 and FF-03PRO. That makes them useful for tuners who rotate parts between multiple Tamiya cars.

Practical benefits of ceramic construction

Ceramic material offers improved hardness and lower friction compared with standard steel, which can translate to steadier diff feel and reduced internal wear over time. These traits are useful for club racing and regular track sessions.

Will these affect diff tuning settings?

The balls themselves do not change recommended shims or grease, but you may notice a slightly different feel. Test and adjust shimming and grease choice to suit your driving style.

What grease should I use with ceramic balls?

Use a diff grease formulated for ball differentials. A medium-viscosity silicone or synthetic grease keeps the balls lubricated while preserving smooth operation.

How often should I inspect them?

Inspect the diff after heavy runs or every few track sessions. Ceramics wear slowly, but regular checks help catch dirt contamination or bearing seat wear early.

Do ceramic balls change drivetrain noise?

You may hear a smoother, slightly quieter operation if the diff was previously rough from worn steel balls. Noise levels depend on overall diff condition and lubrication.
