Associated Electrics have added to their range of Factory Team options parts new precision ground diff drive rings for the Team Associated B6-series of 2WD buggy, SC5M and SC6.1, RC10T4.1 to T6.1 series, and all SC10s using ball diffs. The precision ground diff drive rings are a great option part for those who want the best ball diff possible. The precision comes from a flatter, tighter tolerance diff ring that will result in smoother diff operation and longer life, therefore increasing time between rebuilds.
