Replace TRF417 Cup Joints with Hardened Steel

For hobbyists wanting stronger drive components, the Tamiya Steel Cup Joints (Part No. 54425) upgrade the TRF417 Gear Differential Unit II. These steel joints offer a tougher alternative to the original aluminium cup joints and hold up better under sustained high-power running.

Why Choose the Tamiya 54425 Cups

Material: Durable high-strength steel aimed at longer service life
Compatibility: Made specifically for the TRF417 Gear Differential Unit II
Installation: Removes the need for a Pin Protector (Y1) when fitting more powerful motors

Can I fit these to other model diffs?

They are tailored for the TRF417 Gear Differential Unit II, so compatibility with other models is not guaranteed without checking dimensions.

Are the steel cups heavier than stock?

Steel versions are typically heavier than aluminium, which can affect rotating mass; many users accept the tradeoff for the added durability with powerful motors.

Any installation tips?

Clean mating surfaces before assembly, follow the differential rebuild steps, and verify there is no binding after fitting the new cups.

Should I change my diff oil?

It is good practice to inspect and refresh differential oil when performing this upgrade to ensure optimal performance with the new components.
