Tamiya 54875 TT-02 Oil Gear Differential Unit for RC Cars - Precision Tuning Upgrade  [54875]

Fine-tune your TT-02 with the Tamiya 54875 oil gear differential

The Tamiya 54875 - TT-02 Oil Gear Differential Unit gives hobbyists a practical way to refine handling on TT-02 chassis. This oil-filled differential lets you tailor the internal damping by choosing different silicone oil viscosities, helping you dial in balance between traction and turn-in.

Adjust grip and rotation with silicone oil choices

By changing the silicone oil inside the unit you control how freely the differential gears turn, which affects weight transfer and corner response. Lighter oils promote easier rotation for loose surfaces, while heavier oils slow the gearing for better traction on grippy tracks.

Sturdy components and TT-02 compatibility

The assembly uses glass fiber-reinforced nylon gear case parts, a gasket and four die-cast bevel gears for reliable service. It fits multiple TT-02 variants, but requires the correct universal shaft assemblies for installation (Item 53792 for TT-02 and TT-02D, Item 53791 for TT-02B).
