UM120C
Super smooth for a precision diff, out lasting the diff rings. When doing a diff rebuild clean the balls and if there is a groove in the ring flip the ring over and you are good to go.
Replace the ring next rebuild!
Works in most 1/10 off-road buggy ball differentials.
This is a pack of fourteen replacement 3/32" differential balls for Kyosho electric buggies and trucks, and fits the Kyosho buggy. It will also work with any buggy or truck that uses 3/32" differential balls.
