TRF tuning pack - Tamiya 42194 RC TRF Ceramic Differential Balls 3/32 12pcs  [42194]

Longer life for your ball differential with Tamiya ceramic balls

RC builders wanting a simple, durable upgrade can fit the Tamiya 42194 3/32 Ceramic Differential Balls (12pcs) to replace standard steel balls. These ceramic balls are made to reduce wear and give smoother rotation in your ball differential assemblies.

Works with common TRF chassis types

The Tamiya 42194 set is compatible with multiple Tamiya chassis, including TRF201, TRF502X, FF-03 and FF-03PRO. That compatibility makes them handy for racers and hobbyists who service several Tamiya models.

Why choose ceramic over steel

Ceramic balls resist wear better than steel and lower internal friction in the differential, which can improve efficiency and consistent feel during runs. They are a practical upgrade for those chasing reliability and smoother diff action rather than radical performance claims.
