Model M04M-08/LB is a machined aluminium front C hub finished in light blue anodise, intended as a durable replacement for the factory plastic unit on TAMIYA M03L, M04M and FF02 chassis.
The component functions as the front steering knuckle, providing the exact pivot point for wheel steering and attaching to the steering linkage and舵機. Aluminium improves dimensional stability and wear characteristics compared with standard polymer hubs while preserving OEM steering geometry.
Fitment follows conventional front-suspension service procedure: remove the original C hub, transfer existing pins or bushings where applicable, fit the aluminium unit and confirm steering freeplay and wheel alignment. Check for interference with the steering linkage and adjust toe or camber settings during reassembly to dial in handling.
From a tuning perspective, the aluminium hub is useful for testing front-end stiffness and sharpening steering response; it interacts with shocks, suspension arms and steering components to alter handling balance. Inspect bearing seats and pin interfaces after initial running to verify fitment and wear.
