This aluminium front lower arm includes an integrated spring mount and is supplied as a direct-fit replacement for Tamiya CW-01 variants such as The Hornet and Grasshopper. It retains the stock suspension layout while replacing the original plastic arm to provide a firmer, more consistent mounting point for the front springs.
Fitment notes: install the arm in the OEM lower arm location and use the model's existing hinge pins and mounting hardware. Check hinge pin fit and suspension travel for any binding before final assembly. Reuse OEM ball ends and bushings or bearings consistent with your vehicle's setup.
Use case: JR-LB02-RD gives a fixed spring anchor to help maintain consistent shock and spring setups session to session and to reduce front-end flex that can alter handling during aggressive running.
The JR-LB02-RD is intended for drivers replacing worn plastic lower arms or locking spring position for more predictable setups; always confirm fit and reuse OEM hardware where it remains serviceable.
