Tamiya Sealed Oil Gear Differential Assembly. This is an optional differential intended for the Tamiya TT-02 Chassis.
The Tamiya Sealed Oil Gear Differential Unit is an essential upgrade for improving tuning options on any TT-02 chassis. It allows you to fine-tune your car's handling by adjusting the viscosity of the silicone oil inside the differential housing. Lighter oils are ideal for low-traction conditions, while heavier oils enhance traction on high-grip surfaces. This sealed, oil-filled gear differential provides smoother operation, helping your vehicle achieve better stability and responsiveness on various track surfaces. Compatible with all TT-02 variants.
