Tamiya CW-01 Front Knuckle Arm Aluminium LB021 by GPM  [LB021]

GPM aluminium front knuckle for CW-01 chassis

The LB021 is a precision aluminium front knuckle arm engineered for Tamiya CW-01 (Lunch Box) scale RC cars. Supplied as 1pr, this CNC friendly upgrade replaces the factory plastic knuckles to reduce steering compliance and provide a hard wearing mounting surface for pivot hardware.

Designed with a focus on fit and durability, the aluminium arm reduces steering link flex for improved input feedback and resists wear where bearings and pins locate. It is intended for hobbyist maintenance and performance tuning rather than full size vehicle use.

Installation follows standard upgrade procedure: remove the original knuckle, transfer any bearings or spacers required, fit the aluminium arm and reassemble. After fitting confirm steering centring, suspension geometry and component clearances before operational testing.

A technical upgrade for tuners seeking a stiffer steering platform and improved pivot longevity for CW-01 scale builds.
