This aluminium front upright knuckle arm set is an aftermarket replacement for the TAMIYA TT01E and TT01ED 1/10 scale chassis. The alloy uprights take the place of the standard plastic units and give a firmer mounting for steering linkages, which helps produce a steadier steering feel during track sessions.
Fit these uprights to tune steering geometry and reduce flex where plastic parts might deform. The blue anodised surface identifies the metal construction and offers basic wear resistance; colour does not alter fit. Confirm wheel hexes, steering links, and ball studs for compatibility before installation.
Fitting steps: remove the stock uprights and transfer any bearings or internal hardware to the aluminium replacements, set turnbuckles to avoid binding, and verify that pickup points for tie rods and dogbones match factory tolerances. These parts are intended for model car chassis use only.
