Description
Overview
The Tamiya TT-02 Oil Gear Differential Unit (54875) is a premium sealed gear differential that brings professional-level tuning capabilities to Tamiya's popular TT-02 chassis family. This gasket-sealed unit allows you to fine-tune your car's handling characteristics by changing silicone oil viscosity, providing the versatility needed to optimize performance across different track conditions and driving styles.
Oil-filled gear differentials have become a standard tuning component for competitive RC racing, offering smoother power delivery and adjustable traction characteristics that friction-based differentials cannot match. This TT-02 version includes #3000 silicone oil and is compatible with all TT-02 chassis variants, making it an essential upgrade for hobbyists looking to elevate their car's performance from stock to race-ready.
