Designed to match the rear lower arm layout of Tamiya TL-01, GF-01 and WR-02 chassis, this aluminum arm carries a light blue anodized finish. It replaces the stock plastic arm with a machined part that reduces local flex and gives a steady mounting point for suspension setups used in touring and drift cars.
Fitting follows standard procedures: remove the original arm, inspect hinge pins and mounts for wear, fit the aluminium arm and check full suspension travel for any interference with chassis or bodywork. Perform the work one side at a time and re-check wheel alignment and toe after installation.
Setup impact: an aluminium lower arm lowers compliance at the mount which tightens rear-end feel and sharpens transient response. This is a handling tweak more than a ride-height change, so adjust shock positions and toe to regain the preferred balance.
