Refined Carbon Differential for Better Handling

The Tamiya 84380 - F104 Carbon Integrated Diff Housing and Shaft is an engineered replacement for the stock rear shaft and housing on F104 cars. Combining a bonded carbon shaft with an integrated diff housing reduces rotating mass and improves rotational steadiness, delivering cleaner throttle transitions. Bringing the spur gear closer to the joint helps the car react more immediately to throttle inputs.

Cleaner Assembly for Consistent Results

The layout follows concepts used in 1/12 pan and TRF101 F1 designs, swapping set screw attachments for a tidier, more secure union. The result is a precise fit that stands up to frequent high speed use and aggressive cornering.

Is this a direct swap for F104 cars?

Yes, the part is made to replace the original rear shaft and diff housing on F104 and TRF101 chassis. Confirm gear mesh and clearances when fitting to ensure smooth operation.

Will I notice less drivetrain lash?

The integrated construction and stiffer carbon shaft reduce flex and can translate into a tighter, more predictable drive feel, reducing perceived lash under throttle changes.

How often should I inspect the unit?

Check disk springs, diff plates and the lock nut before each race meeting or after heavy sessions. Clean old grease and reapply the correct diff lubricant to keep consistent performance.
