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

Replacement aluminium knuckle for Lunch Box

The GPM LB021 front knuckle arm is a machined aluminium upgrade for Tamiya CW-01 (Lunch Box) scale RC chassis. Supplied as 1pr, these knuckles replace the OEM plastic units to reduce steering flex and improve durability at the pivot points.

When fitted the aluminium knuckle reduces unwanted movement in the steering linkages, delivering a firmer steering response, and provides a harder wearing mounting surface for kingpin and pivot hardware. This is an aftermarket part intended for hobby use only.

Installation is aimed at modders comfortable removing the front assemblies. Remove the stock knuckles, transfer bearings and pins as required, fit the aluminium replacements and then check steering centring and suspension geometry. Verify there is no interference with tyres or suspension arms before use.

A direct aftermarket alternative to the stock plastic knuckles, suitable for CW-01 builders focused on tuning and component longevity.
