Tamiya TT02 Front Lower Arm Replacement Aluminium TT2055 by GPM  [TT2055]

Replacement Front Lower Arm for TT02

This aluminium front lower arm is supplied as a 1pr replacement for the Tamiya TT02 chassis and is identified by model TT2055. It offers a metal substitute for the standard plastic arm to cut flex around the control pivot and to keep consistent mounting geometry during setup and maintenance.

Installation matches TT02 steering knuckles and hubs but always confirm ball-stud alignment and clearance before final assembly. Use correct fasteners and torque figures for your chassis and run the suspension through full travel after fitting to check for binding. Inspect bearing and pivot surfaces and apply lubrication where needed.

In tuning terms, fitting an alloy lower arm reduces compliance at the mount point and can benefit camber retention and initial steering feel. Consider this component when you need repeatable geometry for testing or when replacing fatigued plastic arms during maintenance.

Use this arm as a direct front lower arm swap on TT02 builds to preserve suspension geometry and provide a firmer mounting point for setup work and routine checks.
