Tune Your Touring Car with the Tamiya 42197 Gear Differential

For racers seeking reliable response from their touring rigs, the Tamiya 42197 TRF417 Gear Differential Unit II delivers a sealed gear solution tailored to high-power brushless motors. The unit accepts a range of silicone oil viscosities to dial traction and acceleration, and its enclosed design reduces routine wear compared with ball differentials. The aluminum diff cup joint helps with power transfer under load, and this setup has been used effectively by TRF competitors on carpet circuits.

Top Performance Details

Enhanced Power Transmission: Suited for high-power brushless motors to help improve traction and forward drive.
Durable Construction: Fully enclosed gear layout lowers upkeep versus traditional ball diffs.
Aluminum Diff Cup Joint: Built to resist stress and support consistent power delivery.
Compatibility: Works with TRF417, TA05 ver.II, and TA05-IFS R chassis.
Custom Tuning: A good starting point is 100000 weight silicone diff oil for balanced handling.

How hard is it to fit this unit to a TRF417?

Installation is straightforward for those familiar with touring car diffs since the unit is designed for TRF417 fitment. Basic tools and careful alignment of the drive components are all that is typically required.

What silicone oil viscosity should I start with?

Begin with the recommended 100000 weight silicone diff oil and adjust up or down to tune understeer or oversteer. Lighter oils make the diff freer, heavier oils increase traction and drive feel.

Will the aluminum diff cup joint reduce breakage?

The aluminum cup joint is stiffer than some stock plastic parts, helping resist deformation under high power and offering steadier performance over time.
