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

Upgraded front knuckle for Lunch Box chassis

The GPM LB021 aluminium front knuckle arm is made for Tamiya CW-01 (Lunch Box) scale RC models. Supplied as a single pair, this replacement swaps in for the factory plastic knuckles to cut down steering play and give a more positive feel to the steering system.

The aluminium component serves to stiffen the steering linkages for quicker input transfer and to protect pivot points with a harder wearing surface. It is intended purely for scale RC maintenance and tuning use.

Installation requires basic chassis teardown skills. Remove the OEM knuckles, transfer any bearings or bushings, fit the new aluminium arms and check suspension geometry and steering neutral position. Inspect clearances around tyres and steering arms before operating the model.

A practical metal upgrade for CW-01 owners wanting reduced steering flex and a more durable pivot surface for tuning-orientated builds.
