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

M07 joint description

The M07-01G 4mm joint is supplied as a replacement/hop-up part for Tamiya M07 series touring car differentials. It fits into the diff assembly to transmit drive while keeping correct spline orientation and rotation.

This item targets compatibility with the Tamiya M07 platform and its hop-up options only. It is intended for replacing worn joints or when changing differential internals during service or set-up tweaks.

Installation is typical for M07 diffs: remove the differential from the chassis, open the carrier, swap in the 4mm joint, confirm clearances and reassemble. Make sure spline engagement is correct and that the joint rotates freely before refitting the differential.

As part of a tuned drivetrain, the joint influences rotational freedom and reliability under load. In combination with correct diff fluid, gear mesh and bearings it contributes to consistent power delivery and predictable handling.
