Tamiya M07 Racing Differential Joint 4mm M07-01G by 3Racing  [M07-01G]

Diff joint technical summary

The M07-01G 4mm joint is intended as a performance-oriented replacement for the Tamiya M07 series differential assembly. It installs within the diff case to transmit torque with accurate spline engagement and minimal freeplay.

Designed for compatibility with standard M07 internals and common hop-up options, this part is for servicing worn joints or for drivers who swap internals to tune diff behaviour. It is not a universal fit for non-M07 platforms.

Fitting notes for technicians: remove the differential carrier, open the casing, replace the existing joint with the 4mm unit and check axial clearance and spline alignment. Verify that the assembly rotates freely and that gear mesh is unchanged before reinstalling into the gearbox to prevent preload or binding.

Performance context: the joint contributes to rotational smoothness and torque transfer under load. In a race setup, pairing the correct diff oil, precise gear mesh and well-maintained bearings will maximise the joint's contribution to consistent corner exit and lap-to-lap stability.
