Control and Traction with the Tamiya 22049 Diff Unit

The Tamiya 22049 Oil Gear Differential Unit is a practical upgrade for RC drivers wanting to tune traction and responsiveness. Suitable for XV-02 and TT-02 platforms, it uses silicone oil changes to alter differential action to match different surfaces and driving approaches.

Functional Uses Across Chassis Types

Fit the unit to the TT-02 to tailor the front or rear differential. For XV-02 users the unit can be installed front, rear or as a centre oil-filled diff for more nuanced handling. Use Item 22050 (06 Module Spur Gear 70T) when setting it up as a centre differential to keep the drivetrain in sync.

Higher viscosity oil increases differential lock, which can help on loose or slippery surfaces, while lower viscosity gives freer slip for technical or high-grip tracks.
Yes. Bearings and shims are common upgrade points; choose precision bearings or different shim stacks to fine tune backlash and gear mesh.
Basic hobby tools like small hex drivers, a shim pick and a set of precision screwdrivers are sufficient. A leak-free filling method for silicone oil will improve setup consistency.
Check O-rings and bearings for wear, replace oil if contaminated, and inspect gear teeth for chips after heavy use to maintain smooth performance.
Yes. Silicone Oil #3000 is provided as a balanced starting point. Experiment with thicker or thinner oils to find the handling you prefer.
