Team Associated ASC31621 Inner Hinge Pin Balls

The Team Associated ASC31621 Inner Hinge Pin Balls locate the inner ends of the suspension arms at the chassis. Instead of a conventional straight hinge pin, this style uses a ball at the inner pivot, which lets the arm swing through its travel while allowing the pivot geometry to be set precisely. The result is a suspension mount that stays tight without binding as the arm cycles.

These pin balls fit the Team Associated TC6.2, TC7, TC7.1 and TC7.2 touring cars and install into the inner arm mounts at the front and rear of those chassis. They are a direct replacement for the parts supplied with the kit, matching original dimensions so your suspension geometry and setup sheet numbers carry over unchanged after the swap.

Inner pivots take constant load and are among the first places slop shows up as a car accumulates run time. Replacing worn pin balls removes that play, restores consistent arm movement and brings back the sharp, predictable handling the chassis had when it was new.
