Premium Aluminum Hollow Ball Set - 12-Piece Decorative Metal Spheres for Home Decor, Wedding Centerpieces & DIY Crafts

This is an Aluminum Hollow Ball Set from Traxxas.

With the understanding that a gram of weight can be the difference between winning and losing a race, Traxxas hollows these steering linkage ball bearings. While reducing the weight, the hollow ball bearings maintain the original tightness in the rod ends.
