Reliable Sealed Gear Differential for Touring Cars

The Tamiya 42197 TRF417 Gear Differential Unit II is built for drivers using high-power brushless motors who want a low-maintenance sealed gear option. Varying silicone oil weights allows fine control of traction and throttle response, and the closed design reduces wear compared with open ball diffs. The aluminium diff cup joint contributes to consistent power transfer and has been used in TRF competition setups, particularly on carpet.

Notable Product Points

Improved Torque Delivery: Matches well with high-power brushless systems to maintain drive out of corners.
Reduced Upkeep: Enclosed gearing limits contaminants and lowers service intervals compared with ball diffs.
Aluminum Diff Cup Joint: Adds stiffness to the drivetrain for dependable performance under load.
Compatibility: Suitable for TRF417, TA05 ver.II, and TA05-IFS R chassis.
Setup Advice: Begin with 100000 weight silicone diff oil to achieve a neutral handling baseline.

Is the unit suitable for competitive use?

Yes, the sealed gear layout and stiff cup joint make it a practical choice for competitive drivers who prefer gear diffs and want reduced maintenance between events.

How do I tune the diff for different tracks?

Adjust the silicone diff oil viscosity to change lockup and power transfer; lighter oil for a freer diff and heavier oil for more traction. Test in small increments to find the right balance for the surface.

Can I maintain this unit at home?

Routine maintenance such as checking oil level and inspecting the cup joint can be done at home with basic RC tools, while more in-depth service should be carried out in a clean workspace.

Will the aluminium cup joint affect driveline vibration?

A stiffer aluminium cup joint can reduce flex that sometimes causes inconsistent power transfer, which often leads to a cleaner feel through acceleration. Proper installation and alignment remain important.
