The JR-DT304-LB aluminum C hub is an aftermarket replacement made for the Tamiya DT-03 chassis. Constructed from machined aluminum, this hub offers a stiffer alternative to the original plastic unit, reducing flex that can undermine steering accuracy and setup consistency.
This hop-up suits builders chasing a tighter steering feel, less wheel play, or setups that shift more load into the steering under higher cornering or stiffer spring rates. Available in light blue or red to complement common upgrade themes.
Fitment advice: remove the stock C hub and refit any shims or inserts as per DT-03 layout, then check toe and hub alignment after installation and ensure full suspension travel is free of binding. Intended solely as an upgrade part for DT-03 scale RC models.
