The JR-DT304-LB aluminum C hub is an aftermarket replacement designed to fit the Tamiya DT-03 chassis. Machined from aluminum, the hub replaces the stock plastic unit to boost steering stiffness and cut flex that can undermine alignment and response during setup and tuning.
Ideal for setups targeting firmer steering and less slop, or when switching to stiffer suspension parts that transfer greater loads through the steering. The hub comes in light blue and red finishes for hop-up continuity.
Installation tips: remove the original C hub, move any spacers or inserts required by the DT-03 layout, re-check hub alignment and toe after fitting, and ensure suspension travel is free of binding. This is a tuning component for DT-03 RC models only.
