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

Front lower arm reinforcement in aluminum

The LB331A aluminum stabilizer is an aftermarket front lower arm reinforcement made for Tamiya CW-01 (Lunch Box) scale rigs. It replaces the stock plastic brace to give a firmer mounting point for the front lower arms and bumper interface, helping chassis reaction through tighter corners and light jump landings.

Machined from 6061 T6 with a 3D hollow-cut profile, the component balances lower mass and increased torsional rigidity suitable for hobby RC use. The kit includes 9 pcs so both sides are covered and it retains the factory mounting geometry, requiring no chassis modification on standard CW-01 layouts.

Included hardware: stainless steel round head screw 3x10 - 3pcs, stainless steel round head screw 3x8 - 3pcs, stainless steel cap head screw 3x8 - 2pcs. Use the supplied screws to attach the stabilizer to the original mounts and check thread engagement before final torque.

As a tuning aid, fitting the stabilizer reduces front-end flex and generally sharpens turn-in; pair the upgrade with spring and damper changes for balanced handling rather than relying on the part alone.

For CW-01 builders after a lightweight, durable alternative to the stock brace, this aluminium stabilizer fits factory points and includes stainless hardware for a straightforward upgrade.
