This JR-TT2B05-GU set supplies machined gun-metal aluminum rear suspension arms designed for the Tamiya TT-02B chassis as a direct aftermarket replacement. The metal arms replace stock plastic rear links to provide a firmer mounting point and a more predictable response during suspension setup and tuning.
As rear link components, these arms influence roll centre, rear track stability, and how the back end reacts to shock damping and spring rate changes. Fit them to refine rear geometry for handling balance, to upgrade for frequent running, or to replace worn plastic parts.
Installation notes: confirm orientation and mounting hole alignment before final torque, reuse original pins and retainers if compatible, and check for full free movement through the suspension travel to avoid binding. Regular inspection of mating surfaces and fasteners keeps alignment consistent over repeated sessions.
