Tamiya Front Knuckle Arms Direct Replacement Silver Aluminum Hornet Grasshopper Fast Attack Wild One F104 F103 TA-50395-S by Jazrider  [TA-50395-S]

Aluminum uprights for Tamiya front suspension

This aluminum front knuckle arm is produced as a direct replacement for the listed Tamiya models: Hornet, Grasshopper, Fast Attack, Wild One, F104 and F103. It replaces the standard plastic uprights to offer a more rigid, wear-resistant mounting point for front hubs and steering linkages.

Compatibility is limited to the specified models. The silver anodized finish and aluminum construction improve resistance to deformation under normal track and off-road conditions typical of small electric buggies and touring cars. When mounting holes and hardware align with the stock part, expect geometry to remain unchanged.

Installation is performed like the original upright swap: remove the stock component, transfer bearings or bushings as necessary, fit the aluminum upright and secure using the existing screws. After installation confirm steering sweep and suspension travel, and perform a short test run to ensure there is no binding. The part is intended to enhance front-end reliability and support tuning adjustments without changing the core suspension geometry.
