Tamiya CW-01 (Lunch Box) Front Lower Arm Stabiliser 9pc 6061 T6 LB331A by GPM  [LB331A]

Aluminium front lower arm support

The LB331A stabiliser is an aftermarket aluminium front lower arm support made for Tamiya CW-01 (Lunch Box) scale rigs. It replaces the original plastic brace to provide a stiffer mounting area for the front lower arms and bumper interface, aiding stability through turns and on small jumps.

Forged in appearance from 6061 T6 with a 3D hollow-cut geometry, the component aims to lower weight while increasing torsional stiffness suitable for hobby-grade running. The kit supplies 9 pieces allowing full installation on both sides and preserves factory mounting geometry so no standard CW-01 chassis changes are required.

Supplied hardware: stainless steel round head screw 3x10 - 3pcs, stainless steel round head screw 3x8 - 3pcs, stainless steel cap head screw 3x8 - 2pcs. Fit these screws to the original mounting points and confirm thread fit before applying final torque.

As a setup tweak, the stabiliser reduces front flex which commonly tightens turn-in; combine its fitment with spring and damper adjustments to achieve the best handling balance.

For builders wanting a durable, lightweight alternative to the stock brace, this aluminium stabiliser fits the CW-01 mounting pattern and includes stainless fasteners for a clean upgrade.
