Tamiya CW-01 Front Lower Arm Aluminum w/Spring Mount by JAZRIDER JR-LB02-BK  [JR-LB02-BK]

Front lower arm for CW-01 chassis

This is an RC-scale front lower arm designed to replace the stock plastic part on Tamiya CW-01 based kits including The Hornet and Grasshopper. The piece is machined from aluminum and includes a spring mount interface so it mates with the factory-style front suspension layout without changing the original geometry.

Fit and compatibility are limited to the listed Tamiya CW-01 platforms. The part is intended as a hop-up for hobby use, offering increased stiffness and wear resistance compared with injection-molded arms. It provides a stable mounting point for the lower suspension link and the spring assembly while preserving servo and steering linkage clearances common to the CW-01 layout.

Installation notes: the arm installs using the same mounting points as the original front lower arm and accepts the factory ball studs and hinge pins. When installing, check pin retention clips and the clearance around the steering knuckle to avoid binding. Use thread locker on metal-to-metal fasteners where appropriate and inspect the spring mount seating after the first run to verify preload and alignment.

Tuning role: swapping to an aluminum lower arm affects front-end stiffness and feedback. Expect a firmer feel at the contact patch and slightly different response under cornering as the arm resists flex. This makes it useful as part of a broader setup change when adjusting spring rates, damper valving, or anti-roll geometry on CW-01 chassis models.

Choose this aluminum front lower arm when you need a direct, durable replacement for CW-01 front suspension that keeps factory geometry and supports progressive tuning of the front end.
