Tamiya M07 Touring Car 4mm Diff Joint M07-01G by 3Racing  [M07-01G]

Summary of the M07 differential joint

The M07-01G is a 4mm replacement joint intended for use in Tamiya M07 touring car differentials. It acts as a hop-up or service replacement inside the diff, transmitting torque while maintaining correct alignment with the diff splines.

Compatibility is limited to the Tamiya M07 chassis and its related hop-up parts; other platforms are not covered. Use this part when refreshing drivetrain internals or swapping worn joints during regular maintenance.

Fitting is straightforward for hobbyists who know M07 diffs: remove the differential assembly, open the case, replace the existing joint with the 4mm unit, check for correct clearance and reassemble. Ensure splines are aligned and rotation is free before reinstalling into the gearbox.

On track, this small component contributes to consistent power transfer. When combined with appropriate diff oil, gear mesh and healthy bearings, it helps preserve predictable handling and traction through laps.
