Precision C-hub tailored for TB04 chassis

This machined aluminium C-hub is an aftermarket replacement intended for TB04-format steering assemblies. The component is produced to give a rigid bearing surface and consistent pivot geometry for 1/10 electric touring vehicles.

Installation follows standard TB04 procedures: remove the original hub, transfer compatible bearings or pins, and secure the aluminium unit with the stock fasteners. Torque conservatively and verify steering travel and centring after fitment to ensure correct operation.

From a tuning perspective, the aluminium C-hub reduces pivot compliance and provides repeatable contact faces for bearings and pins, supporting predictable steering behaviour and easier setup adjustments during testing and race prep.

What tolerances should I check before fitting?

Confirm pivot hole diameter and boss spacing match the TB04 reference. Check bearing seat runout and pin diameter to ensure interference-free fitment.

Any lubrication or bearing prep recommended?

Light, clean grease on metal-to-metal contact areas helps prevent corrosion. Bearings should be clean and either lightly lubricated or replaced if worn for best steering precision.

Does aluminium change pivot geometry or require setup changes?

The unit is dimensionally compatible with TB04 hubs, so geometry remains the same. Expect lower compliance; check toe and steering centring as part of final setup validation.
