These aluminium knuckle arms replace the TAMIYA TT01E and TT01ED front uprights, finished in black anodize and referenced as JR-TT101-BK. They are made to preserve the original mounting locations so steering geometry remains consistent with stock parts.
Setup guidance: using aluminium uprights stiffens the steering mount and reduces deflection at the hub, which can improve predictable steering feedback and make fine-tuning toe and camber responses easier during setup changes.
Fitment caution: ensure that bearing fits and screw engagement match your TT01E/TT01ED configuration before final assembly. No separate hardware or accessory list is supplied.
