Tamiya CW-01 Aluminum Front Lower Arm Stabilizer 9pc Set LB331A by GPM  [LB331A]

Lightweight aluminium lower arm stabiliser

The LB331A aluminium stabiliser is an aftermarket front lower arm reinforcement intended for Tamiya CW-01 (Lunch Box) scale rigs. Replacing the stock plastic brace gives a firmer attachment for the front lower arms and bumper area, helping handling under corner loads and light landings.

Produced from 6061 T6 with a 3D hollow-cut cross section, the part is aimed at reducing unsprung mass while raising torsional capability for hobby RC applications. The pack includes 9 pieces so both sides are covered, and it keeps factory mounting points so no chassis alterations are necessary for standard CW-01 setups.

Included screws: stainless steel round head screw 3x10 - 3pcs, stainless steel round head screw 3x8 - 3pcs, stainless steel cap head screw 3x8 - 2pcs. These fasteners are intended for direct use; check thread fit and torque to spec where applicable.

Fitting the stabiliser will reduce front flex and typically improve initial turn-in; pair this upgrade with spring and damper adjustments to dial in balanced handling rather than expecting large changes from the brace alone.

A straightforward aluminium upgrade that fits CW-01 factory points and includes stainless hardware for quick installation and improved front-end stiffness.
