These upper arm bulks are CNC-oriented replacement components engineered for the TAMIYA TT02 platform and supplied as a front and rear pair in 7075 aluminium. The anodized surface finish improves corrosion resistance and surface hardness while the alloy selection delivers enhanced tensile strength for aggressive tuning and repeated load cycles.
Designed as direct-fit aftermarket upgrades for the TT02 chassis, the metal bulks maintain mounting geometry while reducing flex at the suspension pivot points, aiding consistent handling and setup reproducibility. Packaging and compatible model information follow.
