Front Locking Coupler Upgrade for the Tamiya 22047 Kit

The Tamiya 22047 Front Direct Coupling Set converts the front differential of XV-02 and TT-02 models into a direct coupling, locking both front wheels together. This delivers steadier straight-line acceleration and more predictable braking on low-grip layouts.

Driving Characteristics After Fitment

By removing front differential action you trade some cornering freedom for improved traction under power and on braking. This setup is particularly useful on gravel, dirt and other surfaces where front grip is a priority.

Included Components

  • Aluminum Front Direct Coupling x1
  • Steel Direct Cups x2
  • Direct Coupling Ring Gear (39T) x1
  • Bevel Pinion Gear (for 39T gear) x1
  • 2x9.8mm Stainless Steel Shafts x2
  • Axle Rings x2
  • 2.6x6mm Cap Screws x4

Fitment Compatibility

Compatible with XV-02 and TT-02 chassis types, the kit is an easy upgrade path for Tamiya 22047 owners seeking better traction on loose circuits or rally stages.

Yes, for rally-style stages with loose surfaces this coupling helps with launches and stability under braking, making it well suited to club-level events.
Since the front diff is replaced, focus diffs and oils on the centre and rear units; check overall drivetrain balance to match the new front behaviour.
Yes, the conversion is reversible as long as you keep the original parts and follow the correct reassembly procedure when reinstalling the oil-filled front differential.
Gear ratio changes are not normally required, but drivers may fine-tune pinion and spur choices to suit the altered traction and track conditions.
