This replacement set provides RC-scale front upright knuckle arms for TAMIYA TA01, TA02W, DF01 and Hotshot chassis. The alloy uprights are intended to replace the factory plastic uprights and to provide a consistent metal mounting point for steering assemblies and suspension links. The light blue finish makes the alloy components easy to identify while building and tuning.
Fitment is intended for the listed Tamiya chassis and assumes reuse of original fasteners and bearings. Installation commonly requires removal of the front hubs, transfer of the existing bearings and steering links, and reinstallation with the stock hex screws; confirm alignment before final torque. These uprights are designed as a tuning upgrade to reduce upright flex and improve steering consistency under load.
The description focuses on compatibility, installation context and tuning use on RC touring and vintage Tamiya models, and does not imply application beyond RC-scale vehicles.
