Tamiya 54875 TT-02 Oil Gear Differential Unit for RC Cars - Track Tuning Kit  [54875]

Track tuning for TT-02: the Tamiya 54875 oil gear differential

The Tamiya 54875 - TT-02 Oil Gear Differential Unit is built for drivers who want more setup options from their TT-02 chassis. Its oil-filled design provides adjustable internal resistance by swapping silicone oils, letting you change how the car behaves in corners.

Use silicone oil to tailor on-track behaviour

Changing the silicone oil alters how quickly the diff gears rotate, which impacts cornering balance and throttle response. Lighter oils suit loose or dusty surfaces, while denser oils help maintain grip on tackier surfaces.

Robust build and required parts

Components include a glass fiber-reinforced nylon case, a gasket and four die-cast bevel gears for dependable performance. It works across TT-02 variants but needs the correct universal shaft kits to fit: Item 53792 for TT-02 and TT-02D, Item 53791 for TT-02B.
