This RC-scale rear hub and knuckle arm is engineered for TAMIYA TT01, TT01E and TT01ED chassis. Machined aluminum with a red finish replaces the factory plastic hub to improve wear resistance and ensure repeatable mounting at the rear suspension locations.
Compatibility is limited to the specified TT01 variants. The component interfaces with existing wheel hubs, uprights, and fasteners on those chassis without changing the basic suspension geometry.
Installation follows standard rear-hub replacement practice: remove the factory hub assembly, install the aluminum hub/knuckle arm in the original orientation, and secure using the existing fasteners to factory torque patterns. After fitting, verify wheel alignment and free rotation of the hub to confirm there is no binding. The item is intended as a maintenance or durability upgrade rather than a chassis redesign.
As a tuning aid the aluminum rear hub reduces plastic wear points and provides a consistent mounting surface for the wheel assembly, helping preserve rear wheel alignment during repeated use.
