Tamiya CW-01 Aluminium Front Arm Bulk - JR-LB05-BK by Jazrider  [JR-LB05-BK]

CW-01 aluminium front arm replacement

This aluminium front arm bulk is supplied as a scale replacement for Tamiya CW-01 platforms including The Hornet and Grasshopper. It swaps in for the original plastic front arm bulk and retains the factory geometry and mounting points while offering a more rigid fixing for the front suspension.

As a structural piece it reduces flex where the steering and suspension pick up loads. That extra stiffness changes steering feedback and suspension motion, so you should expect a different on-car feel compared with the stock plastic component and confirm clearance and travel after fitting.

Fitting is simple for anyone used to CW-01 maintenance: remove the factory front arm bulk from the bulkhead, move over any pins or retainers required, and secure the aluminium unit into the same locations. Afterward, inspect steering linkages, tie-rod position and full suspension droop to ensure nothing binds.

Use this item as part of broader setup adjustments to tune front-end stiffness. Since it alters the chassis structural stiffness rather than spring rates, combine it with checks of toe, camber and ride height to fine tune handling balance.
