This front lower arm is an aluminium replacement for the stock plastic arm fitted to Tamiya CW-01 based models such as The Hornet and Grasshopper. The component is machined and includes a spring mount so it integrates with the factory front suspension geometry.
Fitment is specific to the listed Tamiya CW-01 platforms. The hop-up arm increases rigidity and wear resistance compared with injection-molded parts, delivering a dependable mounting location for the lower suspension link and the spring while retaining standard servo and steering linkage clearances on CW-01 chassis.
Fitment and installation: the arm installs on the same points as the OEM lower arm and accepts factory CW-01 ball studs and hinge pins. When fitting, inspect pin retention clips and steering knuckle clearance to ensure free movement. Use thread locker on metal-to-metal fasteners as required and check spring mount seating after the first run for correct preload and alignment.
Effect on handling: an aluminium lower arm reduces flex, giving a firmer front feel and more consistent feedback. This typically changes cornering response and may require matching adjustments to springs, damping or anti-roll to rebalance the chassis.
Pick this aluminium front lower arm for a durable, geometry-preserving upgrade that supports precise tuning of CW-01 front-end dynamics.
