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

M07 differential joint overview

This 3Racing M07-01G is a 4mm differential joint produced for use on Tamiya M07 series RC touring car models. It is an RC-scale replacement/hop-up component intended to slot into the differential assembly of the M07 chassis, serving the role of transmitting drive from the diff outwards while maintaining correct alignment.

Compatibility is focused on the Tamiya M07 platform and related hop-up configurations; this listing does not cover other chassis. The part is labelled for the M07 and is used when replacing worn joints or when swapping differential internals during routine maintenance or set-up changes.

Installation is straightforward for hobbyists familiar with M07 diffs: remove the differential housing from the chassis, open the diff case, replace the existing joint with the 4mm unit, verify clearances and reassemble. Confirm spline alignment and free rotation before reinstalling the differential into the gearbox to avoid binding.

Tuning role: this joint is a small but precise element in the drivetrain that affects rotational freedom and reliability under load; used in combination with correct differential oil, gear mesh and bearing condition, it helps preserve consistent power transfer for lap-to-lap stability.
