M04M tunable aluminium ball diff

This aluminium ball differential is an upgrade part intended for the Tamiya M04M differential location and compatible Tamiya kits that accept the same layout. It replaces the stock unit with a metal housing and a ball-based mechanism designed for predictable torque transfer during setup changes.

Sold as a replacement hop-up rather than an entire gearbox, the unit is aimed at allowing centre traction adjustments so you can tune handling balance without altering suspension or motor components.

Installation and tuning notes:

Carefully extract the original differential from the M04M housing using your standard disassembly procedure and inspect the mating faces for any wear before fitting the aluminium unit.
Select the correct grease and shims to set preload for the feel you want, and check rotation by hand to confirm smooth operation before sealing the chassis.
Carry out bench testing and low-speed runs to validate drivetrain smoothness and to further tweak handling after installation.

Is this an OEM part?

No, this is an aftermarket hop-up designed for the Tamiya M04M differential location and compatible models that use the same ball diff layout.

How often should I service it?

Service intervals depend on running conditions; inspect balls and bearings after heavy sessions and clean and re-grease as needed to maintain consistent performance.

Will it change handling dramatically?

It lets you alter centre traction and torque bias, which can noticeably affect mid-corner stability and turn-in, but major handling changes usually require suspension or powertrain adjustments too.
