This RC aluminium front upright (knuckle arm) is a direct aftermarket replacement intended for TAMIYA TT01E and TT01ED chassis. The part preserves the original steering geometry while using a machined metal component rather than the stock plastic.
Intended use: replace worn or damaged plastic uprights to gain improved durability and a stable mounting surface for steering links, allowing finer tuning of toe and steering feel. Installation normally uses the original steering pins and wheel hub hardware and only requires standard wheel removal and refit procedures on the TT01E/TT01ED.
Note the fitment is explicitly TT01E and TT01ED; compatibility with other TT-01 variants is not guaranteed without checking. The uprights are suited to hobbyists seeking a reliable upgrade for predictable steering feedback and longer service life.
