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

Aluminium front arm bulk designed for CW-01 platforms

This aluminium front arm bulk is an RC-scale replacement for the stock plastic front arm bulk on Tamiya CW-01 platforms such as The Hornet and Grasshopper. It replaces the original part while maintaining factory geometry and mounting locations, providing a firmer mounting point for the front suspension.

As a structural component it reduces flex at steering and suspension pick-up points, which changes steering feel and suspension behavior. Expect a different on-track sensation compared with the factory plastic piece and confirm full travel and clearance after fitting.

Fitting is straightforward for those who have serviced CW-01 cars before: remove the original front arm bulk from the front bulkhead, transfer any pins or retainers as needed, and install the aluminium unit into the same mounting positions. After installation, check steering linkage, tie-rod alignment and suspension travel to ensure there is no binding.

Use the part as part of a handling tune to influence front-end stiffness. Because it alters chassis stiffness rather than spring characteristics, combine it with toe, camber and ride height adjustments to achieve the handling balance you are targeting.
