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

Light blue aluminium knuckles made for M03M

This aluminium front knuckle arm kit is an aftermarket upgrade tailored to the Tamiya M03M. The light blue finish provides a clear visual cue while the aluminium body limits steering flex compared with stock plastic parts, resulting in a more direct steering response on road and tight circuits.

Fitment checklist: verify the chassis is the M03M type before purchase or fitting. These arms replace the factory front knuckles and are meant to work with the M03M wheel hubs and steering link hardware. Do not force them onto other chassis types without confirming mounting compatibility.

How to fit: remove the front hubs and steering links, swap in the aluminium knuckles, and reuse OEM fasteners when they fit correctly. Inspect for binding across suspension travel and ensure servo arm and driveshaft clearances are maintained. You may need to tweak turnbuckle lengths to preserve correct toe and steering centre.

Performance impact: aluminium knuckles reduce steering system compliance, which can enhance turn-in precision and keep alignment more consistent under load. This suits drivers moving to firmer front setups, but always test changes gently before full-speed running.
