This aluminium rear suspension arm set fits the TAMIYA TT-02B chassis and is supplied as model JR-TT2B05-RD. The red-finished arms replace stock plastic parts to provide a firmer mounting point for the rear suspension while preserving scale appearance.
Installation is a direct replacement using the existing TT-02B rear mounting points, so no chassis alterations are needed. After installing, check fastener torque, wheel alignment and suspension travel before operating the vehicle.
As a tuning component, the arms reduce flex relative to standard plastic parts and help the rear suspension retain its intended geometry under load, supporting more consistent handling during setup changes. The red finish aids quick visual identification of upgraded parts during maintenance.
