Free-spinning front hub upgrade for TB Evo III

The Tamiya 50991 TB Evo3 One-way Unit is a compact mechanical upgrade that refines steering feel on the TB Evo III chassis. During acceleration the front hubs can disengage, which helps the car initiate turns more readily and reduces the resistance that can cause the front to wash out.

Improved rotation and mid-corner control

When installed on a TB Evo III, the one-way unit alters how power transfer affects the front end, promoting smoother rotation through tighter corners. This change can be especially useful at club meets where consistent turn-in and predictable behaviour matter lap after lap.

Reliable construction and straightforward installation

Constructed to withstand regular use, the Tamiya 50991 fits into the TB Evo III assembly with minimal fuss. It is a sensible option for drivers replacing old parts or trialling handling tweaks without major chassis surgery.

What setup changes should I try after fitting the unit?

After fitting, revisit front toe and camber as the car may respond differently; a slightly sharper toe-in or small camber tweak can regain stability while keeping improved turn-in.

Is the unit a direct replacement for the stock part?

Yes, it is intended to fit the TB Evo III front assembly. If you run non-standard hubs or aftermarket front gear, confirm fitment before installation.
