The JR-DT306-GR is a machined aluminum front upright intended as an aftermarket replacement for the TAMIYA DT-03 steering knuckle. It installs in place of the stock upright and provides a direct mounting point for the wheel hub.
The component uses a green anodized finish and machined contact surfaces to offer consistent mounting geometry and improved stiffness compared with typical plastic uprights. It is aimed at hobby tuning and reliable fitment in model assemblies.
To install, remove the original DT-03 upright, transfer any reusable bearings or locating pins, fit the JR-DT306-GR into the steering assembly, and secure with the appropriate fasteners. This item is intended for RC model chassis applications only.
