Tamiya CW-01 (Lunch Box) Front Knuckle Arm Aluminium by GPM LB021  [LB021]

Front knuckle arm for CW-01

The GPM LB021 is an aluminium front knuckle arm designed for use on Tamiya CW-01 (Lunch Box) scale RC cars. Supplied as 1pr, this replacement hop-up replaces the stock plastic knuckles to increase steering rigidity and reduce flex under load while keeping the part clearly identified as an RC-scale accessory.

In typical use the aluminium knuckle serves two roles: it reduces compliance in the steering linkages for crisper input response, and it provides a harder wearing mounting surface for kingpin or pivot hardware. The part is intended for hobby maintenance and tuning, not for real vehicle applications.

Installation is straightforward for users experienced with basic chassis disassembly. Remove the stock knuckle, transfer any required bearings or pivot hardware, fit the aluminium arm, and verify suspension geometry and steering centring after assembly. Check for correct clearance with nearby suspension and tyre components before running the model.

This aluminium front knuckle arm is a direct aftermarket upgrade for CW-01 chassis owners who want reduced steering flex and a metal alternative to stock plastic components, making it suitable for tuning-oriented builds and routine upgrades.
