These black aluminium knuckle arms replace the standard plastic units on Tamiya Hornet, Grasshopper, Fast Attack, Wild One, F104, and F103. JAZRIDER parts are chosen to improve robustness and deliver steadier steering response for club runs and casual racing.
Made from quality aluminium, the knuckles resist breakage better than plastic, reducing the chance of on-track failures. The firmer component preserves steering geometry under higher loads.
Aluminium knuckles reduce flex and sharpen steering inputs, giving a clearer feedback loop between driver and car. That clarity helps with consistent lap times and predictable handling.
Designed to fit multiple Tamiya platforms, these knuckle arms are suitable for Hornet, Grasshopper, Fast Attack, Wild One, F104, and F103, making them a practical upgrade across different kits.
