GPM Tamiya CW-01 Front Knuckle Arm Aluminium LB021 - RC Spare Part  [LB021]

Aluminium front knuckle for CW-01 scale rigs

The GPM LB021 is an aluminium front knuckle arm engineered for Tamiya CW-01 (Lunch Box) scale RC cars. Supplied as 1pr, this hop-up replaces the original plastic knuckles to reduce steering flex and provide a more rigid mounting point for kingpin or pivot hardware.

In normal running the aluminium knuckle decreases compliance in the steering linkages so inputs feel crisper, while offering a tougher wear surface for pins and bearings. This part is intended for hobby tuning and maintenance, not for use on full size vehicles.

Fitting is straightforward for anyone familiar with basic chassis service. Remove the stock knuckles, move across any bearings or bushes needed, install the aluminium arms and then verify steering centring and suspension geometry before running. Confirm there is adequate clearance around the tyres and surrounding suspension parts.

This direct aftermarket upgrade reduces steering deflection compared with the stock plastic knuckles and suits CW-01 builders who favour metal components for tuning and longevity.
