XV-02/TT-02 Oil Gear Diff Unit, chassis accessory

The XV-02/TT-02 Oil Gear Diff Unit brings adjustable differential tuning to compatible RC chassis through an oil-filled gear design. Built for the XV-02 and TT-02 platforms, it uses the viscosity of the oil inside the differential case to alter how the internal gears transfer drive, giving a more deliberate way to refine handling than a fixed setup. The set shown includes the main differential housing, ring gear, internal bevel gears, cross shafts, outdrive cups, bearings, O-rings, gasket, shims, pins, screws and gear oil. Those parts support servicing, rebuilding or converting the drivetrain section with matching components in one package. On the XV-02 chassis, combining this unit with Item 22050, the 06 Module Spur Gear 70T for XV-02 Gear Differential, allows use as a center differential. That adds a specific configuration path for builders working on that chassis layout. This accessory suits tuning sessions, maintenance work and planned drivetrain changes on compatible RC cars. It fits naturally into bench work where differential action, sealing parts and rotating hardware are being refreshed together, and it gives repeatable setup scope through oil choice rather than through a full hardware swap each time.
