The M04M-08/LB is a light blue anodised aluminium front C hub intended to replace the original plastic hub on TAMIYA M03L, M04M and FF02 chassis where a machined metal option is required for the steering assembly.
Functioning as the steering knuckle, this part provides the pivot for the front wheels and links to the steering linkage and舵機. Aluminium offers tighter dimensional control and better wear resistance than common polymer hubs while maintaining the stock steering geometry on compatible TAMIYA frames.
Installation uses standard front-suspension procedures: remove the stock C hub, transfer pins or inserts if present, fit the aluminium hub and then check that steering moves freely and wheels are aligned. Confirm clearance around your steering linkage and make any toe or camber adjustments during reassembly.
For tuning this hub is handy when testing front-end rigidity and steering feedback; it interacts with shocks, arms and steering parts to change handling. Inspect-bearing seats and pin contact areas after early runs to watch for wear.
