Oil-tunable differential

Tamiya TT-02B

This replaces an axle's standard differential with a sealed unit that uses oil to control its action. It gives you another way to tune how the two wheels share drive, using the oil choice and the matching joints and shafts required by this version.

Installation notes

  • For one TT-02B axle, use 22049 with one 22062 gearbox-joint set and one 53791 universal-shaft set.
  • The listed quantities cover one differential and both shafts on that axle. A front-and-rear conversion needs a second complete combination.
  • Tune the sealed differential with the appropriate oil and follow the 22062/22049 cup arrangement. Keep these joints distinct from cups used with the original kit differential.
