Tamiya Front Upright Knuckles Silver Anodized Aluminum for Hornet Grasshopper Fast Attack Wild One F104 F103 TA-50395-S by Jazrider  [TA-50395-S]

Direct-replacement uprights for classic Tamiya chassis

Manufactured as a direct swap for the listed Tamiya models — Hornet, Grasshopper, Fast Attack, Wild One, F104 and F103 — these aluminum front knuckle arms are intended to replace the original plastic uprights. They provide a more robust mounting point for the front wheel hubs and steering linkages on RC buggies and touring cars.

Compatibility is confined to the named models. The component is finished in silver and made from aluminum to better resist deformation during typical track or off-road use. When the mounting holes align with the stock hardware, expect no change to fundamental suspension geometry.

Installation mirrors the stock procedure: remove the original upright, transfer bearings or bushings as required, fit the aluminum piece and secure with the existing screws. After fitting check steering sweep, toe and camber, then run the vehicle at low speed to ensure no binding occurs in the steering or suspension travel. The part is supplied to enhance durability and tuning stability without altering primary suspension design.
