Tamiya TT-02 Gear Differential Upgrade TT02-09 by 3Racing  [TT02-09]

TT-02 Differential Notes

This gear differential is an aftermarket replacement built for Tamiya TT-02 chassis care and tuning. The internal gear layout replaces stock differentials when you need steadier driveline behaviour or to refresh worn internals. It is a purpose-built RC part for model use only.

Compatibility is centred on TT-02 based builds. When preparing the install, inspect gearbox alignment, check spur and pinion engagement, and confirm bearing health to ensure smooth operation. The unit mounts in place of the original differential carrier using the stock mounting points.

From a setup perspective, a gear differential determines how drive torque is split across driven wheels, which has a direct effect on turn-in grip and mid-corner balance. This is a practical choice for hobbyists wanting a simple, consistent replacement without switching to a ball-type differential.

Choose this gear differential to restore predictable traction on TT-02 drivetrains and follow routine gearbox maintenance with correct lubrication for long service life.
