The ARA330810 is Arrma's complete steel pivot ball set — 22 balls covering the suspension links, shock eyelets and steering, in one packet. It fits fourteen vehicles across the 223S, MEGA and 4S ranges, spanning 2WD and 4X4 in 1/10 and 1/8 scale.

Pivot balls are the small steel spheres that sit inside the plastic ball cups at the ends of turnbuckles, shocks and steering links, letting each joint articulate while the suspension moves. They wear rather than break: the ball loses its polish, the cup opens up, and the joint develops play. Multiply that across every link on the car and the result is vague steering, wandering alignment and a chassis that no longer holds a setup.

Because the whole set arrives together, it's the sensible option during a full rebuild or when a car that's done a lot of hours has gone loose everywhere at once. Replacing balls in ones and twos usually just moves the play to the next joint along.
