Tamiya CW-01 Front Arm Bulk, Aluminium Upgrade - JR-LB05-GU by Jazrider  [JR-LB05-GU]

Front arm bulk in aluminium for CW-01 fitment

This is an aftermarket aluminium front arm bulk intended for the Tamiya CW-01 chassis family, including The Hornet and Grasshopper, sold as JR-LB05-GU. It replaces the factory front arm bulk to provide a more rigid mounting point for front suspension components on 1/10-scale vehicles.

Made from machined aluminium with a gun metal finish, the component prioritises stiffness and consistent geometry over lowering mass. By reducing flex at the front mounting points, steering becomes more predictable and front wheel alignment holds better during dynamic maneuvers.

Fitting is a direct swap with the CW-01 front arm bulk locations on the chassis. Because it is a structural element of the front suspension, drivers should expect changes in steering feel and handling; this helps when tuning for sharper entry or reduced compliance at the front.

Maintenance is limited to keeping the part clean and checking fastener holes for wear after heavy use. The gun metal finish helps mask superficial marks, but treat the item primarily as a chassis stiffness and setup improvement.
