This aluminum rear hub and knuckle arm is intended for TAMIYA TT01, TT01E and TT01ED chassis, offering a metal replacement to the OEM plastic component. The red finish gives a durable contact surface for the rear wheel assembly.
The component is compatible only with the listed TT01 variants and interfaces with the stock wheel hubs, uprights, and existing fasteners without changing the suspension geometry.
Installation mirrors standard hub replacement: remove the factory unit, mount the aluminum hub/knuckle arm in the same orientation, and secure with the original hardware to the recommended torque. After installation, verify wheel alignment and free rotation to confirm correct fitment. This is a practical durability and maintenance upgrade rather than a chassis overhaul.
In use the part reduces plastic wear, stabilizes the rear wheel mounting point, and helps retain alignment over repeated runs.
