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

Details on the M07 differential joint

The M07-01G is a 4mm differential joint designed for use in Tamiya M07 series touring car differentials. It is supplied as a replacement or hop-up component that transmits drive while maintaining proper spline alignment inside the diff.

Compatibility is specific to the Tamiya M07 platform and common hop-up arrangements; this listing is not applicable to other chassis types. Use this joint when replacing worn components or when refreshing internal diff parts during setup changes.

Fitting follows standard M07 diff procedures: remove the differential assembly, open the case, replace the existing joint with the 4mm unit, check clearances and reassemble. Confirm that splines are aligned and rotation is smooth to avoid drivetrain binding.

In tuning terms, the joint is a small but precise part of the drivetrain that can affect rotational freedom and reliability. Used with appropriate diff oil, correct gear mesh and healthy bearings, it supports steady power transfer for predictable handling.
