Tamiya Hornet/Grasshopper/Fast Attack/Wild One/F104/F103 Silver Aluminum Knuckle Arms Front Upright by JAZRIDER TA-50395-S  [TA-50395-S]

Front upright for Tamiya chassis

This is an aluminum front knuckle arm designed as a direct replacement for the listed Tamiya models: Hornet, Grasshopper, Fast Attack, Wild One, F104 and F103. It is an RC-scale accessory intended to replace factory plastic uprights to provide a stiffer, more wear-resistant mounting point for the front wheel hubs and steering linkages.

Compatibility is limited to the model names given above. The part is finished in silver and constructed from aluminum to resist deformation under track or off-road use typical to small-scale electric buggies and touring cars. Expect unchanged geometry when swapping with the original upright when mounting points align with stock hardware.

Installation is straightforward on vehicles using the matching Tamiya upright layout: remove the original upright, transfer any bearings or bushings as needed, fit the aluminum upright in place and secure with the existing screws. After installation confirm steering range, toe and camber settings, and perform a short test run to ensure the uprights do not bind the steering or suspension travel. This part is intended to assist in tuning front-end feel and long-term reliability rather than changing primary suspension geometry.
