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

Aluminium front knuckle arms for M03M

This aluminium front knuckle arm set is an RC-scale hop-up part designed for the Tamiya M03M chassis. The light blue finish identifies the upgrade visually while the aluminium construction provides a stiffer steering geometry compared to stock plastic pieces. The text below focuses on fitment notes, simple installation considerations, and how these arms affect tuning and handling on track or practice sessions.

Compatibility and fitment: confirm your model is the M03M variant before installation. These arms are intended to replace the stock front knuckle arms on M03M assemblies and work with the existing wheel hubs and steering linkages that the chassis uses. Do not modify or attempt to fit to non-M03M layouts without checking part interfaces.

Installation guidance: remove the front hubs and steering links, swap the stock arms for the aluminium units, and reuse OEM hardware where possible to retain correct geometry. Check for binding across the suspension travel and ensure clearance for servo horns and drive shafts. Small adjustments to turnbuckles or steering link lengths may be required to maintain toe and steering centring.

Tuning role: aluminium knuckle arms reduce flex in the steering assembly, which can sharpen initial steering response and maintain alignment under load. That change can be useful when tuning for quicker turn-in or when pairing with firmer suspension settings. Expect slightly different feedback from the front end; verify behaviour on low-speed laps before full-speed runs.
