This light-blue aluminium front lower arm includes an integrated spring mount and serves as a direct replacement for the Tamiya CW-01 platform, covering models such as The Hornet and Grasshopper. It replaces the OEM plastic arm to provide a firmer front suspension characteristic.
Installation is straightforward: remove the wheel and front hub, detach the original lower arm from its hub and chassis mounts, then fit the aluminium arm into the same points using the stock screws and pins. The spring mount keeps the stock spring positions so existing springs and cups remain compatible.
Use this arm to reduce flex at the pivot and to help achieve more consistent steering behaviour. Introduce the part as part of a step-by-step tuning process and observe handling before adjusting other elements like shocks or anti-roll bars.
