This replacement set is an RC-scale front upright knuckle arm assembly designed for TAMIYA TA01, TA02W, DF01 and Hotshot chassis. The alloy uprights replace the original plastic pieces to provide a firmer metal mounting point for steering parts and suspension links. The light blue finish helps with quick identification during assembly and tuning.
Fitment is for the listed Tamiya platforms and assumes reuse of the existing bearings and fasteners. Installation generally requires removing front hubs, transferring bearings and steering links, and securing the uprights with the stock hex screws; always check alignment before final tightening. As a tuning item these uprights help to reduce upright flex and stabilise steering geometry under load.
The description emphasises compatibility, installation guidance and the tuning benefits on RC touring and classic Tamiya cars.
