TT-01d Front Lower Arm Alloy Upgrade - TT055D for TAMIYA by GPM  [TT055D]

Front lower arm upgrade for TT-01d

This aluminium front lower arm is an aftermarket replacement manufactured by GPM for the TAMIYA TT-01d platform and is supplied as one pair. It provides a durable, firmer substitute to the factory plastic arm for hobbyists focused on handling and setup work.

Compatibility and use: Designed to mount into the TT-01d front suspension, the arm installs using the standard retaining hardware common to the platform. It functions as the lower structural element in the suspension, affecting steering return and camber behaviour when paired with the original uprights and steering links.

Setup benefits: Upgrading to alloy increases the consistency of the suspension under load, helping to isolate other setup changes such as damper tuning and toe adjustments. This is a component-level tuning part intended to refine on-road performance rather than alter chassis layout.
