This aftermarket aluminum rear knuckle arm is a direct-fit replacement for hobby-grade TAMIYA TA01, TA02, DF01 and FF01 models. It provides a metal alternative to the original plastic knuckle, helping to maintain consistent rear suspension geometry and serving as a robust mounting point for hubs and axle assemblies.
The component is supplied in gun metal and is cut to match stock mounting points so no chassis alterations are typically required. In use it reduces unwanted toe and camber movement under load, supporting stable handling during routine driving and setup.
Fitting the part is a standard swap: remove the OEM knuckle, move bearings or pins across, and secure the new knuckle with the existing hardware. After installation check bearing alignment, suspension clearances and that driveshafts and hub carriers rotate without binding.
