These aluminum rear suspension arms are an aftermarket hop-up made for owners of Tamiya TA-01 RC chassis who want a metal alternative to the stock plastic arms. The light blue anodized coating makes the parts easy to identify while the aluminum body keeps suspension geometry stable under typical club-track and hobby loads.
Installation note: the arms are designed to replace rear suspension arms on TA-01 layouts with the same mounting pattern, and they fit using the chassis' existing hinge pins and hardware. Inspect hinge pins and pivot bushings during fitting to ensure correct articulation.
Tuning role: fitting aluminum rear arms alters rear-end flex and yields a firmer pivot compared with plastic parts. Introduce them gradually during setup changes to refine roll balance and rear traction, and confirm clearances with nearby drivetrain and suspension components after installation.
