TAMIYA CW-01 The Hornet Grasshopper Front Lower Arm Aluminum with Spring Mount by JAZRIDER JR-LB02-LB  [JR-LB02-LB]

Aluminum Front Lower Arm for Tamiya CW-01

This aluminum front lower arm with integrated spring mount is an RC-scale replacement part intended for the Tamiya CW-01 platform, including The Hornet and Grasshopper variants. Finished in light blue, the component serves as a direct drop-in for chassis that use the CW-01 front suspension layout and is designed to replace the standard plastic arm for a firmer feel in the front suspension.

Installation is straightforward for hobbyists familiar with basic teardown: remove the wheel and front hub, detach the original lower arm from the suspension hub and chassis mount, then fit the aluminum arm into the same mounting points using the original hardware. The integrated spring mount accepts the same spring locations as the stock part, so original springs and spring cups remain compatible.

In tuning, this arm is intended to offer increased rigidity at the front lower arm pivot, which can reduce flex under load and provide a more predictable steering response. Use it as part of incremental setup changes, observing handling differences before changing other elements like shock valving, spring rates, or sway bars.
