This aluminium front upright knuckle arm set is a scale replacement made for TAMIYA TA01, TA02W, DF01 and Hotshot chassis. The gun metal finish identifies the surface treatment and aluminium construction reduces flex when compared with standard plastic uprights. The item improves steering rigidity and service life without altering chassis geometry when correctly fitted.
Fitment notes: remove the original front uprights and transfer any required bearings or bushings from the stock components. Attach the aluminium knuckles to the steering hubs and suspension uprights using the vehicle's existing hardware where it is compatible. After assembly, confirm steering travel and wheel alignment, and re-check fastener torque following the first run.
Performance notes: swapping to aluminium uprights increases front-end stiffness and can sharpen steering response while offering more direct suspension feedback. Expect to make small camber and toe adjustments after installation to dial in the handling balance.
