Tamiya 42142 - 3mm Ceramic Differential Balls for TRF and Touring Cars (12-Pack)  [42142]

Refine Differential Performance with Tamiya Ceramic Balls

For tuners aiming to improve TRF series drivetrains, the Tamiya 42142 3mm ceramic differential balls deliver a measurable reduction in friction compared with standard steel or tungsten balls. These ceramic replacements help the differential turn cleaner and can lengthen service intervals.

Performance Benefits Compared to Steel or Tungsten

Ceramic balls roll with tighter tolerances and resist surface wear, which promotes smoother engagement inside the diff. That smoother action helps maintain consistent behaviour during high speed passes and prolonged club sessions, while also cutting down on frequent rebuilds.

Who Should Fit These Balls

The 12-piece set is ideal for committed hobbyists and racers who want consistent handling from their TRF machines. When fitted correctly, the ceramic balls contribute to steadier throttle transitions and longer-lasting internals.
