Tamiya TB04 Lightweight Aluminium C-Hub TB4019 by GPM  [TB4019]

Lightweight C-hub for TB04 applications

This aluminium C-hub serves as a direct replacement for the plastic steering hub on TB04-style chassis. Machined for accurate fit, it gives a more rigid mounting point for steering arms and suspension pivots in 1/10 electric touring car setups.

Installation is simple for those familiar with TB04 assembly: remove the factory hub, transfer compatible pins or bearings, and secure the aluminium component with the original fasteners. Typical hand tools such as hex drivers are sufficient, but always verify alignment and steering movement after fitting.

In practical tuning terms, fitting an aluminium C-hub limits pivot flex and gives uniform contact for pins and bearings, helping the steering feel more precise and repeatable during setup changes. Confirm compatibility with TB04-derived models before purchase.
