This alloy front lower arm is an aftermarket RC-scale replacement part produced by GPM for the TAMIYA TT-01d platform, supplied as 1 pr. It is intended to serve as the front suspension lower arm, offering a firmer alternative to stock plastic components while keeping scope limited to model-scale tuning and maintenance.
Use and fit: Designed to mount in the front suspension of TT-01d series chassis, the arm replaces the standard lower arm without requiring additional tools beyond common RC workshop items. It functions as a structural component in the suspension assembly, affecting camber and steering response when used with existing hubs, uprights, and linkage on the TT-01d.
Tuning role: Swapping to an alloy lower arm can increase assembly stiffness and consistency under load, which helps drivers assess other setup changes such as shock valving, toe settings, and anti-roll bar adjustments. It is a component-level change useful for on-road setup work rather than a complete chassis conversion.
