Performance-focused aluminium ball differential

This aluminium ball differential is supplied as a precision hop-up to suit the Tamiya M04M differential location and other chassis sharing the same geometry. The metal housing and serviceable ball mechanism are aimed at delivering repeatable torque transfer and predictable handling response for competitive tuning work.

Intended as a replacement differential rather than a complete gearbox, the unit enables fine adjustments to centre traction and torque distribution so setup changes can be targeted at balance rather than component swaps.

Installation and tuning notes:

  • Remove the OEM differential from the M04M housing using standard workshop practice, inspect mounting faces and bearing seats for wear before fitting the aluminium unit.
  • Set preload using calibrated shims and a controlled application of grease; check for uniform rotation and minimal endplay during bench tests.
  • Validate settings with measured low-speed trials, then make incremental changes to grease weight or shim stack to tune torque bias for your racing conditions.

What measurement points should I inspect?

Inspect the diff housing faces, output cup seating, and bearing bores for concentricity and wear; any deviation can affect preload and torque transfer consistency.

Recommended shimming approach?

Begin with a minimal shim stack to establish baseline rotation, then add thin shims to increase preload until the desired torque bias is reached without binding under load.

Grease selection guidance?

Use greases specified for ball differentials; higher viscosity increases traction bias while lower viscosity yields freer diff action. Match grease choice to track conditions and handling targets.
