Tamiya Silver Anodized Front Knuckle Arms Durable Upgrade for Hornet Grasshopper Fast Attack Wild One F104 F103 TA-50395-S by Jazrider  [TA-50395-S]

Durable silver knuckle arms for Tamiya

This part is an aluminum front knuckle arm manufactured as a direct swap for the listed Tamiya vehicles: Hornet, Grasshopper, Fast Attack, Wild One, F104 and F103. It is intended to replace the standard plastic uprights to provide a tougher, longer-wearing mounting point for the front hubs and steering links.

Use is limited to the models specified. The silver finish and aluminum construction help resist bending or wear under typical off-road or track stresses seen on small electric buggies and touring cars. When mounting points align with stock hardware, expect no change in basic suspension geometry.

Installation follows the stock upright procedure: remove the original upright, transfer bearings or bushings as needed, install the aluminum upright and secure with the existing fasteners. After installation check steering sweep and suspension travel, then run a short test to confirm there is no interference. The component aims to improve reliability and reduce wear without modifying core suspension geometry.
