The JR-M701-LB aluminium front steering knuckle is a CNC-friendly aftermarket replacement tailored for the TAMIYA M-07 chassis. It replaces the factory plastic knuckle with a denser material to reduce elastic deformation in the steering assembly and extend service life under regular use.
Fitting follows standard M-07 procedures: remove wheel and hub, unfasten the OEM knuckle and install the aluminium knuckle at the factory mounting points. Reuse serviceable hardware, verify kingpin alignment and steering arm posture, and apply the recommended torque to all fasteners to prevent binding while preserving free rotation.
Functionally this part increases steering assembly stiffness without modifying suspension geometry. The result is steadier toe settings and repeatable caster feedback, useful for consistent setup changes. Confirm correct bearing seating and unobstructed hub rotation after installation to maintain precise handling.
