Supplied as 1pr (2 pcs), this alloy front and rear upper arm bulk is intended for the TAMIYA TT02 chassis. It replaces the OEM plastic bulkheads to deliver a firmer anchor for the upper suspension link at both ends.
Engineered to match TT02 mounting points, the pieces act as a direct-fit hop-up with no chassis modification required in most cases. In practical setup they help maintain consistent link geometry under cornering and braking, which supports more reliable lap-to-lap tuning.
Installation uses standard TT02 practices: retain usable original screws and ball studs, avoid excessive torque when tightening, and confirm wheel alignment plus link free-play after fitting. Regular checks should focus on thread integrity and re-torqueing after the first few runs.
