Reinforced Differential Cups by Tamiya 54238

The Tamiya 54238 RC M05Ra Ball Differential Cup Set offers a tougher alternative to stock aluminium joints for M-05 cars. It is intended for those who run rally style or rough-surface sessions and need parts that resist chipping and deformation.

Durability Tailored for Rough Tracks

The reinforced cups are made to tolerate the kind of shocks and side loads common off tarmac. This helps reduce premature failures during demanding runs while keeping the diff behaviour consistent for predictable cornering.

Compatibility Notes

The Tamiya 54238 kit is compatible with M-05 variants that use the Tamiya 54194 Ball Differential Set, fitting as a direct swap for the aluminium components. It is a practical upgrade for hobbyists upgrading drivetrain resilience.

Are special tools required to change the cups?

No special tools are needed beyond the basic small hex drivers and pliers used for standard M-05 diff work.

Can I use these on a stock powertrain?

Yes, they improve durability on stock cars too, especially if you run on gravel or mixed surfaces.

Do they affect diff feel or tuning?

The aim is durability with minimal change to the diff action, so tuning approaches that worked before should remain valid.
