One set in a bag
It is custom-size order from the manufacture
The large diameter ring is put inside of the ball diff or gear diff, and the small on put outside
Through intensive testing with different size balls we have determines that as strange as it sounds the outside pod ball size makes a significant difference in how the car handles so what we have done is split the difference between. The std kit balls are small and these ball studs are sized in between the small and what we felt was too big. The center ball now has the spacer built in and more thread length.
