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

Aluminum front lower arm stabilizer

This GPM LB331A aluminum stabilizer is an aftermarket front lower arm reinforcement designed for Tamiya CW-01 (Lunch Box) scale rigs. It replaces the plastic brace to provide a stiffer mounting point for the front lower arms and the bumper interface, improving chassis response during cornering and small-jump landings.

Manufactured from 6061 T6 aluminum with a 3D hollow-cut profile, the part balances reduced weight with torsional strength appropriate for hobby-grade RC running. The set contains 9pcs total, allowing installation on both sides and retaining factory mounting geometry so no chassis modification is required for standard CW-01 layouts.

Included hardware from the factory: stainless steel round head screw 3x10 - 3pcs, stainless steel round head screw 3x8 - 3pcs, stainless steel cap head screw 3x8 - 2pcs. Use these screws to secure the stabilizer to original mounting points and verify thread fit before final torque.

When tuning, use the stabilizer to reduce flex at the front lower arms; this typically tightens turn-in and stabilizes the bumper area. Expect subtle changes—pair with spring and damper adjustments for best balance rather than relying on the part alone.

For CW-01 builders seeking a lightweight, durable substitute for the stock brace, this aluminum stabilizer provides a simple upgrade that integrates with factory mounting and included stainless hardware.
