FAQ

Fit a Ball Differential to Your Tamiya XV-02 or TT-02

The Tamiya Ball Differential Set (39T) is aimed at modelers who want a more controlled rear end on loose tracks. By offering a limited slip characteristic it improves traction and can stabilise the rear during throttle application.

Package Contents and Role

Differential Joint A & B: The connection parts that form the diff coupling.
Ball Differential Ring Gear (39T): The 39-tooth ring component that sets the gear ratio.
Bevel Pinion Gear: Works with the 39T ring for proper gear engagement.
Large Ball Diff Alloy Plates: Alloy plates that secure the ball stack and resist deformation.
Thrust Plates and Spring: Components that apply the correct preload for consistent differential action.
Ball Bearings: Includes sizes 850 and 1280 to reduce resistance and support durability.
Steel Balls: Both 3mm and 1/16-inch balls are included for accurate ball differential operation.
Ball Differential Grease: A tube of grease is provided to keep contact surfaces lubricated and predictable.

Does this improve traction on loose dirt?

Yes. The ball differential introduces limited slip action that increases rear traction on loose or low-grip surfaces, helping to reduce spin under power.

Can I adjust the feel after fitting?

Adjustment is possible by changing thrust plate preload and the amount/type of grease. Small changes will noticeably alter how the diff transfers torque.

Is special tooling required to assemble this kit?

No specialised tools are required beyond standard RC sockets, hex drivers and a clean workspace. Patience when seating the balls and bearings is key for a smooth result.

What should I check during routine maintenance?

Inspect ball surfaces, bearings and alloy plates for pitting or wear, clean old grease, and reapply the supplied ball differential grease for consistent performance.
