This aluminium C-hub is an RC-scale replacement part produced by GPM for use with the TB04 platform as indicated in the product name. It replaces the standard steering hub components with a machined aluminium piece intended to offer a firmer mounting point for steering linkages and suspension pivots on 1/10 electric touring car setups.
Installation is straightforward for hobbyists familiar with the TB04 layout: remove the stock C-hub, transfer any existing pins or bearings if required, and secure the aluminium unit using the original hardware. No special tools beyond standard hex drivers are normally needed, but check fitment and steering geometry after installation to ensure alignment and free movement of the steering assembly.
In tuning terms, an aluminium C-hub is used to reduce flex at the steering pivot and to provide a consistent contact surface for pins and bearings, which can make steering response feel more direct. This part is presented as an RC accessory for chassis setup and should be used only on compatible TB04-based models.
