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

TT-02 Differential Overview

This gear differential is an aftermarket replacement intended for Tamiya TT-02 chassis upkeep and tuning. The gear-type design replaces the factory differential when you want stable driveline characteristics or to refresh worn components. It is a dedicated RC model part.

Compatibility is concentrated on TT-02 builds. Prior to installation, inspect gearbox mounts, check spur and pinion engagement, and verify bearings are in good condition for correct alignment. The unit typically replaces the stock differential carrier and uses the original mounting points.

In handling terms a gear differential modifies how torque is shared between driven wheels, influencing cornering traction and mid-corner composure. This unit is aimed at modellers seeking a dependable drivetrain swap or a baseline hop-up without adopting a ball differential.

Use this differential to maintain predictable TT-02 traction and observe standard gearbox servicing with suitable lubrication for longer component life.
