This aluminum front arm bulk is an RC-scale replacement part intended for TAMIYA CW-01 based kits including The Hornet and Grasshopper. It replaces the stock plastic front arm bulk and provides a stiffer mounting point for the front suspension assembly, with a blue aluminum finish for durability and corrosion resistance.
Compatibility is limited to CW-01 platform models listed above. Installation replaces the original plastic bulk using the vehicle's existing fasteners, check screw engagement and suspension travel after fitting to prevent binding. The part is supplied as a single component intended to work with original hardware and surrounding suspension parts.
On setup and tuning this aluminum bulk changes the front suspension feel by reducing flex at the mounting point, which can affect steering feedback and alignment stability. Use it as part of a systematic tuning approach, testing alignment and roll characteristics after fitment to determine its effect on handling for your specific setup.
