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

Front Lower Arm Solution for TT02

This aluminium front lower arm is supplied as 1pr and matches Tamiya TT02 suspension mounting points, identified by model TT2055. It serves as a metal replacement for the standard plastic arm to cut flex where the control linkages attach and to keep repeatable geometry during setup and service.

Installation fits TT02 standard knuckles and hubs, though you should check ball-stud alignment and any potential interference before securing. Use correct screws and torque settings for your chassis and verify full suspension travel after refit. Where applicable, check mating surfaces and apply light lubrication to pivot areas.

From a tuning perspective, swapping to an alloy arm reduces compliance at the pivot and can improve camber stability and initial turn-in feel. This part is useful when comparing setups or replacing cracked or fatigued plastic arms.

Use this arm as a direct front lower arm replacement on TT02 builds to preserve geometry and to provide a firmer mounting point for setup adjustments and maintenance.
