TAMIYA CW-01 Front Lower Arm Aluminum with Spring Mount JR-LB02-LB by Jazrider  [JR-LB02-LB]

Stiffer Aluminum Lower Arm for CW-01 Chassis

This aluminum front lower arm with integrated spring mount is an RC-scale replacement part designed for the Tamiya CW-01 platform, including The Hornet and Grasshopper variants. Finished in light blue, the piece installs where the stock plastic arm sits to give a firmer front end and reduced flex under load.

Installation is simple for anyone familiar with basic disassembly: remove the wheel and hub, unbolt the original lower arm from the hub and chassis mount, then fit the aluminum arm into the same mounting points using the factory screws and pins. The integrated spring mount uses the same spring positions as the stock component so your original springs and cups remain usable.

As a tuning step, this arm increases rigidity at the front pivot to tighten steering response and make handling more predictable. Fit it as part of incremental changes and assess handling before adjusting shocks, springs, or anti-roll links.
