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

Precision aluminum lower arm for CW-01 chassis

This is an aluminium front lower arm made as a replacement for the original plastic component on Tamiya CW-01 kits including The Hornet and Grasshopper. The part is CNC-machined and features a spring mount that aligns with the factory front suspension geometry.

Compatibility is confined to the listed CW-01 platforms. As an aftermarket hop-up it offers improved rigidity and wear resistance over injection-molded arms, creating a reliable mounting point for the lower suspension link and the spring while keeping standard servo and steering linkage clearances on the CW-01 layout.

Installation guidance: mount the arm using the factory mounting points and reuse standard CW-01 ball studs and hinge pins. Check retention clips and steering knuckle clearance during fitment to avoid interference. Use a medium-strength thread locker on metal fasteners where needed and verify spring mount seating after the first run to ensure correct preload.

Setup effects: upgrading to an aluminum arm reduces flex at the front end and tightens feedback to the driver. You may notice a firmer contact response and a different cornering feel, which can be balanced by adjusting spring rates, damper valving, or anti-roll settings on CW-01 vehicles.

Choose this aluminium lower arm when you need a robust, factory-geometry-preserving replacement for CW-01 front suspension that withstands repeated use.
