The Tamiya 22050 - 06 Module Spur Gear (70T) is a straightforward upgrade for XV-02 chassis owners aiming to improve turning balance. Swapping this spur into the existing differential lets you convert the standard unit to a centre differential, helping equalise front and rear wheel speeds for neater, more predictable corner exits.
Replacing the ring gear inside the stock differential with this spur gives a subtler power split and smoother torque transfer across the drivetrain. The centre differential arrangement benefits drivers who want improved stability and reduced understeer on mixed surfaces.
Designed specifically for the XV-02, this spur gear integrates with the factory gear differential components. For a complete centre differential setup, pair the 22050 - 06 Module Spur Gear (70T) with Item 22049 as advised in the original guidance.
