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

Alloy Front Lower Arm for Tamiya TT02

This alloy front lower arm is an RC-scale replacement part produced for Tamiya TT02 chassis, supplied as 1pr and identified by GPM model TT2055. It is intended as a direct-replacement arm for the front suspension, offering a metal alternative to stock plastic arms to reduce flex at the control point and to provide consistent mounting geometry during setup and maintenance.

Installation is straightforward on TT02-spec steering knuckles and hubs, but verify ball-stud alignment and clearance before completing reassembly. Use appropriate fasteners and torque to the values recommended for your chassis, and check suspension travel through the full range after fitting to avoid binding. As with any alloy upgrade, inspect mating surfaces and pivot points for proper seating and lubrication where applicable.

The arm's role in tuning is mechanical: changing to an alloy arm can alter flex characteristics and provide a firmer front-end connection, which affects camber retention and initial steering response. Consider this part when you want consistent geometry for setup comparisons or when replacing worn plastic arms during routine maintenance.

Use this arm as a like-for-like front lower arm replacement on TT02 builds to maintain suspension geometry and to provide a more rigid mounting point for tuning and regular servicing.
