Tamiya M03M Aluminium Front Knuckle Arms Light Blue M03M-06/LB by 3Racing  [M03M-06/LB]

Light blue aluminium knuckles for M03M

This aluminium front knuckle arm set is an upgrade made for the Tamiya M03M platform. The light blue finish makes it easy to spot on the car while the aluminium construction cuts steering flex versus the stock plastic knuckles, giving a firmer steering centre and crisper response during corner entry.

Fitment notes: confirm your model is the M03M variant before fitting. These knuckles are intended to replace the stock front pieces on M03M assemblies and pair with the original wheel hubs and steering links used by the chassis. Avoid forcing them onto non-M03M layouts without checking the mounting interfaces.

Installation tips: remove the front hubs and steering links, swap the plastic arms for the aluminium units, and reuse OEM screws where they match. Check suspension travel for any binding and ensure there is clearance for servo horns and drive shafts. Minor turnbuckle or link length tweaks may be needed to retain correct toe and central steering alignment.

Tuning impact: aluminium knuckles reduce steering assembly compliance, which can improve initial steering bite and help keep alignment under load. This works well if you are trimming for quicker turn-in or running slightly stiffer front springs; always test at low speed first to confirm the handling change.
